The CA1, CA2, and CA3 regions are the principal pyramidal cell fields in the hippocampus (Figure 3) and are often the focus of research concerned with memory encoding and retrieval (McNaughton and Morris, 1987; Chevaleyre and Siegelbaum, 2010). Zhao et al. Neuroscience research articles are provided. In effect, the CA2 functions to prevent “overheating” of the entire hippocampal network (Boehringer et al., 2017). doi: 10.1111/ejn.12689, Swanson, L. W., and Cowan, W. M. (1977). Proc. Administration of an estrogen α receptor agonist impaired social recognition, while administration of an estrogen β receptor agonist prolonged it. Ann. J. Neurosci. Figure 6. J. Neurosci. The dentate gyrus has been reported to project axons to the stratum radiatum of the CA2 region in guinea pigs, cats, rats, and mice (McLardy, 1963; Hirama et al., 1997; Lavenex et al., 2009; Kohara et al., 2014; San Antonio et al., 2014; Dudek et al., 2016). They suggested that RGS14 my act as a natural brake to limit LTP and synaptic plasticity within the CA2 following stimulation. Social psychological contributions to the decade of the brain. doi: 10.1016/0301-0082(94)90019-1, Stevenson, E. L., and Caldwell, H. K. (2014). Mem. Studies on the structure of the cerebral cortex. May 14, 2014 - In humans, the importance of the hippocampus for social memory was famously illustrated by the case of Henry Molaison, who had much of his hippocampus removed by surgeons in 1953 in an attempt to cure (C) Golgi images illustrating the dorsal and ventral aspects of the hippocampus. Like memory, emotions arise from activity in distinct regions of the brain, primarily a tiny almond-shaped structure called the amygdala, which integrates emotions and motivation. Long-term potentiation (LTP) has been widely accepted to be the cellular underpinning of synaptic plasticity, and memory acquisition, storage, and retrieval in the central nervous system (Caruana et al., 2012).

Also shown in this image is the stratum lucidum (SL; green: synaptophysin staining) where the mossy fibers terminate (highlighted by the high density of synaptophysin staining in green). social neuroscience 2 psychology or related fields. (2015) reported that the CA2 showed weak discrimination between spatial contexts; that is, the place fields in this region showed less change in response to alterations in the shape of a context compared to other regions. Selective lesions of the dentate gyrus produce disruptions in place learning for adjacent spatial locations. 13, 3916–3925. The Two-Trial Social Memory test assesses cognition, namely the ability to recognize novel versus familiar animals, in rodent models of CNS disorders. John F. Kihlstrom . Eur. Given the efficacy of TeNT lesions, they then investigated the behavioral consequences of CA2 inactivation. There are also distinct projections from layer 3 of the EC to the SLM of the CA1 and CA2 regions (referred to as the temporoammonic pathway; blue).

They reported that silencing of RGS14 resulted in marked improvements in both the Morris water maze and novel-object recognition task. Path integration and the neural basis of the ‘cognitive map’. Upon closer examination, Lorente de No (1934) reported that a small area within the regio inferior differed enough in its cytoarchitecture and connectivity to warrant a distinction from the rest of the area. The Social Psychology specialization at the University of South Florida is a research-based training program leading to the Ph.D. degree. Mou, X. Massachusetts Institute of Technology77 Massachusetts Avenue, Cambridge, MA, USA. (2015) suggested that the combination of a larger number of place fields per cell and an increase in field size accounted for the reduction of spatial information. A never-before-met juvenile mice is placed into the home cage of a test … (2007). The investigators reported that cell ensembles in CA2 were particularly sensitive to subtle changes in familiar environments; that is, they observed a robust change in ensembles in the CA2 that were disproportionate to the magnitude of contextual change (Wintzer et al., 2014; Dudek et al., 2016). 2-chloroadenosine decreases long-term potentiation in the hippocampal CA1 area of the rat. The hippocampal CA2 ensemble is sensitive to contextual change. They are synthesized in the paraventricular and supraoptic nuclei of the hypothalamus, with vasopressin also synthesized in the suprachiasmatic nucleus and released from the pituitary, where they bind to receptors found throughout the central nervous system and periphery (Gimpl and Fahrenholz, 2001; Insel, 2010). Find in Worldcat; The Cognitive Neuroscience of Memory: An Introduction Howard Eichenbaum Abstract . 109, 579–593. Memory for individual conspecifics is not only necessary to engage in meaningful relationships but is also required to express appropriate behavioral responses based on previous encounters (van der Kooij and Sandi, 2012; Jacobs et al., 2016). However, investigations have provided evidence suggesting that the CA2 is, in fact, highly plastic, though highly selective for the type of stimulus that can induce LTP (Caruana et al., 2012). Spatial firing patterns in the CA2 were as consistent as in the CA3 or CA1 when the rats visited the same box shape repeatedly. Social and Affective Neuroscience Program Overview This program supports basic investigations of circuit-level neurobiological mechanisms underlying affect, social behavior, and social cognition in healthy humans and animals. Effects of long-term estrogen replacement on social investigation and social memory in ovariectomized C57BL/6 mice. This provides further support that LTP and synaptic plasticity at CA2 synapses play a role in social recognition, and provides further insight into the function of the aforementioned connectivity between the CA2 and extrahippocampal regions (Wersinger et al., 2002; Prediger and Takahashi, 2005; DeVito et al., 2009; Caruana et al., 2012). Res. NEUROSCIENCE High-capacity auditory memory for vocal communication in a social songbird K. Yu1*, W. E. Wood1*, F. E. Theunissen1,2,3† Effective vocal communication often requires the listener to recognize the identity of a vocalizer, and this recog-nition is dependent on the listener’s ability to form auditory memories. In their investigation, there was a 40% reduction in the number and density of non-pyramidal neurons in the stratum pyramidale of CA2 in schizophrenic and manic-depressive patients compared to controls (Benes et al., 1998). Lee et al. 14 No. Soon after, the test mouse was placed in a cage with the familiar mouse and a new mouse. 57, 40–48. This module provides an overview of the new field of social neuroscience, which combines the use of neuroscience methods and theories to understand how other people influence our thoughts, feelings, and behavior. The effects of adenosine on the development of long-term potentiation. Slices in which ChR2 was co-expressed with TeNT in CA2 pyramidal neurons produced little to no synaptic response in CA1 neurons when CA2 neurons were illuminated (Hitti and Siegelbaum, 2014). When considering the findings in social neuroscience, we discover that a neurobiological process takes place under these conditions that results in poor academic and behavioral performance in school, which is escalated by zero tolerance policies and punishments in the schools. It requires integration of multimodal sensory information with output from limbic circuits and those that encode memory of prior social experiences Nakazawa, K., Quirk, M. C., Chitwood, R. A., Watanabe, M., Yeckel, M. F., Sun, L. D., et al. Find out more. 2005 May 13;6:36. (2014) used compartment analysis of temporal activity fluorescence in situ hybridization (catFISH) imaging to compare cell ensembles in CA1, CA2, and CA3 subregions in mutant mouse lines lacking either NMDA receptors at the CA3 synapse (CA3-NR1 KO) or at the perforant path inputs from the entorhinal cortex to the dentate gyrus (DG-NR1 KO). Prog. A three-chamber test of sociability was used to compare performance between CA2-YFP mice and CA2-TeNT mice. Kind thanks to Dr. Kyle Honegger for detonating a memory retrieval process and kindly donating the image of the PEP-19 staining. Granule cells of the DG send their axons (mossy fibers; red) through the hilus to the CA3 stratum lucidum (SL) and the border of the CA2 stratum radiatum (SR) and SLM. The Cognition, Neuroscience, & Social (CNS) program has ... Our current research focuses on comparative cognition and the neurobiology of emotion, stress, learning, and memory; Social: This is the branch of psychology that studies individuals in the social context. On the 11th trial, the experimental mouse was then exposed to a novel mouse. 29, 2676–2683. © Università degli Studi di Roma "La Sapienza" - Piazzale Aldo Moro 5, 00185 Roma Expanding on this, Smith et al. The neuroendocrine basis of social recognition. The NeuN stain also highlights the difference in the width of the cell layers between CA2 and CA1 (visible at dashed line). Focal photostimulation over a wide range of intensities delivered to CA1 stratum oriens and stratum radiatum regions evoked robust monosynaptic potentials in the CA1 pyramidal neurons in slices in which ChR2 was co-expressed with YFP in CA2 pyramidal neurons. I. In addition, CA2 neurons make reciprocal, bilateral extrahippocampal connections (purple) with the medial entorhinal cortex (MEC), supramamillary nucleus (SMN) and medial/lateral septum/diagonal brand of Broca (MS). (2014). A reduction of nonpyramidal cells in sector CA2 of schizophrenics and manic-depressives. One possible explanation is the abundance of A1 adenosine receptors, of which the population is denser in the CA2 region than other hippocampal regions (Zhao et al., 2007; Jones and McHugh, 2011). The CA2 region of the hippocampus is a somewhat obscure area lacking in an understanding of its form and function. Social recognition memory in animals is essential for social hierarchy, mate and offspring recognition, territorial defense, interspecies recognition, and for the general establishment and maintenance of groups (Ferguson et al., 2002; Jacobs et al., 2016). Researchers show that deep reinforcement learning can be used to design more efficient nuclear reactors. Social interaction can be seen as a dynamic feedback loop that couples action, reaction, and internal cognitive processes across individual agents. The Memory Care Center is a collaborative care relationship between Neuroscience Group and St. Paul Elder Services. Social encounters facilitate new learning and help modify preexisting memories throughout the lifespan of an organism. Mem. Psychiatry 44, 88–97. doi: 10.1126/science.1140263, McHugh, T. J., and Tonegawa, S. (2009). 3, 225–229. Contrary to the findings reported by Wintzer et al. It is a byproduct of both intracellular and extracellular ATP metabolism and is released with other neurotransmitters and metabolized by ectoprotein kinases (Wieraszko et al., 1989; Mitchell et al., 1993).

In the last two decades, important new understanding of how the brain affects mental illness, addiction, and other psychosocial conditions has occurred. They reported slower habituation in CA2-silenced mice, indicating that the CA2 is integral in contextual habituation (Boehringer et al., 2017). The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. First, the researchers allowed one mouse, known as the “test mouse,” to spend time with another mouse for two hours, letting the mice become familiar with each other. Recognition in rats was reported to only last about 30–60 min following acquisition as opposed to mice where it was reported to last for days. 589(Pt 8), 1885–1891. The CA2-TeNT group demonstrated impaired social memory, given that there was no decrease in time that the CA2-TeNT mouse spent exploring a previously encountered mouse (Hitti and Siegelbaum, 2014). Brain Res. Turn the design process into a game. doi: 10.1002/(sici)1098-1063(1998)8:6<608::aid-hipo3>3.0.co;2-7, Moser, M. B., Moser, E. I., Forrest, E., Andersen, P., and Morris, R. G. (1995). In this test, the amount of time that the experimental mouse spent interacting with a novel, unrelated mouse was compared to the time spent interacting with a familiar co-housed littermate in order to measure social recognition (Hitti and Siegelbaum, 2014). Social Neuroscience By Tiffany A. Ito and Jennifer T. Kubota. doi: 10.1016/j.physbeh.2007.06.020, Matochik, J. The research was funded by the RIKEN Brain Science Institute, the Howard Hughes Medical Institute, the JPB Foundation, and the Japan Society for the Promotion of Science. Neurosci. Based on these results, it is possible that estrogen activity may be a contributing factor that influences this behavior. 17, 89–102. U.S.A. 100, 6192–6197. Science 322, 900–904. Furthermore, CA2 silencing did not impair other hippocampus-dependent memory process, including novel-object-recognition and spatial memory, nor did it alter locomotor activity, anxiety-like behavior, or olfaction (Hitti and Siegelbaum, 2014). The CA2 has been shown to receive both intrahippocampal and extrahippocampal inputs (Figure 6). Nevertheless, burgeoning research into this area has established the role of CA2 in social memory processes, with a particular focus on social recognition, and as such, dysfunction in this area has been implicated in the social impairments common to a number of psychiatric diseases. Science 297, 211–218. doi: 10.1523/jneurosci.14-12-07347.1994, Kajiwara, R., Wouterlood, F. G., Sah, A., Boekel, A. J., Baks-te Bulte, L. T., and Witter, M. P. (2008). MH commented and edited the manuscript. In this test, the experimental mouse was exposed to a stimulus mouse for four consecutive trials then introduced to a novel stimulus mouse on the fifth trial. Coupled with the fact that, prior to the discovery of these direct, reciprocal CA2-entorhinal cortex inputs, the only known pathway between the entorhinal cortex and CA fields was a polysynaptic one, which could potentially lead to the loss of critical information necessary for recognition (McNaughton et al., 2006; Rowland et al., 2013). They concluded that critical components of the LTP were missing in the CA2 and offered some molecular causes to explain the lack of LTP (Zhao et al., 2007). A review. The dorsal hippocampus (Figure 1) receives input from the caudolateral band of the entorhinal cortex and sends excitatory projections to dorsal parts of the subiculum, presubiculum, and post-subiculum. This field of study is c… Social cognitive processes can be clustered in three domains associated with (a) perceptual processing of soc… “The inhibition of ventral CA1 leads to impairment of the social memory,” Okuyama says. Then to go in and control those specific cells is really on the cutting edge.”. The researchers also showed that they can suppress or stimulate these memories by using a technique known as optogenetics to manipulate the cells that carry these memory traces, or engrams. Furthermore, oxytocin and vasopressin have both been considered to play a role in learning and memory (Gimpl and Fahrenholz, 2001). Neurobiol. (2007) compared the patterns of expression of NMDA receptor mRNA in the CA2 and CA3 and found that they were expressed evenly across both regions. doi: 10.1002/hipo.10037, Wersinger, S. R., Ginns, E.

This program supports basic investigations of circuit-level neurobiological mechanisms underlying affect, social behavior, and social cognition in healthy humans and animals. Neuron 66, 560–572. Altered patterns of dynorphin immunoreactivity suggest mossy fiber reorganization in human hippocampal epilepsy. Dissociating hippocampal subregions: a double dissociation between dentate gyrus and CA1. Your assigned work should be theory­driven, clear, and concise. The putative existence of 'basic emotions' and their defining attributes represents a long lasting and yet unsettled issue in psychology. High-frequency stimulation of CA3 region, activating the Schaffer collateral inputs to the CA1, creates a robust potentiation within the CA1 region, inducing and sustaining LTP (Caruana et al., 2012). The researchers set out to test this hypothesis using optogenetics: By engineering neurons of the ventral CA1 to express light-sensitive proteins, they could artificially activate or inhibit these cells by shining light on them as the mice interacted with each other. (2014) introduced a novel change to a familiar environment, the experimental protocol employed by Mankin et al. After raising the extracellular calcium levels of the preparation and using a higher frequency of tetanic stimulation, they managed to induce LTP at CA2 stratum radiatum synapses (Simons et al., 2009; Caruana et al., 2012; Dudek et al., 2016). MIT researchers develop novel EV emissions model to quantify importance of vehicle charging patterns and impact of ambient temperature on EV emissions levels. Function of the hippocampus in memory formation: desperately seeking resolution. Recent findings from the neuroscience literature is beginning to paint a picture of the self as a product of complex, interrelated systems of memory. A theory of hippocampal function in memory. doi: 10.1016/j.neuron.2010.04.013, Choleris, E., Gustafsson, J. We are part of a larger experimental psychology area, CNS (Cognition, Neuroscience, and Social). The axons forming the perforant path (blue) arise from layer 2 of the EC and show synaptic contacts in the granule cell molecular layer of the dentate gyrus (DG) and the stratum lacunosum moleculare (SLM) of the CA3 region. The hippocampus proper is defined by the dentate gyrus and Cornu Ammonis (CA). There is also a slight widening of the cell layer at the border of CA2 and CA3 (upward pointing arrow). doi: 10.1016/0361-9230(83)90037-0, Smith, A. S., Williams Avram, S.

When recalling a stored memory, strengthened connections in the entorhinal cortex-CA3 pathway, along with strengthened CA3 recurrents, allow for a reactivation of the CA3 pattern corresponding to the original item. Jones, M. W., and McHugh, T. J. According to Mankin et al. The stratum oriens is a deep, relatively cell-free layer containing the basal dendrites of the pyramidal cells and various interneurons, along with some of the myelinated Schaeffer collateral connections from CA3 to CA1 (Figure 4). Abstract Social cognitive neuroscience examines social phenomena and processes using cognitive neuroscience research tools such as neuroimaging and neuropsychology.This review examines four broad areas of research within social cognitive neuroscience: (a) understanding others, (b) understanding oneself, (c) controlling oneself, and (d) the processes that occur at the interface of self and others. Hippocampal synaptic enhancement and information storage within a distributed memory system. A selective decrease in the relative density of parvalbumin-immunoreactive neurons in the hippocampus in schizophrenia. Behav. 10, 675–697. Cell type-specific genetic and optogenetic tools reveal hippocampal CA2 circuits. Hypothalamic and other connections with dorsal CA2 area of the mouse hippocampus. Neurol. When the researchers monitored activity of neurons in the ventral CA1, they found that after a mouse was familiarized with another mouse, a certain population of these neurons began to respond specifically to the familiar mouse. Norman and O’Reilly (2003) developed a computational model of recognition memory that provides insight into the interplay between the hippocampal subregions, which function to mediate the storage and retrieval of recognition memory and may be transferable to other forms of hippocampal-dependent memories. J. Physiol. (2008). Neuron 85, 190–201. These cells, found in a region of the hippocampus known as the ventral CA1, store “social memories” that help shape the mice’s behavior toward each other. Miniaturized device activates drugs in a small region deep within the brain. to discriminate between other individuals, which would potentially require simple circuitry to process the information. What is neuroscience? The vasopressin 1b receptor is prominent in the hippocampal area CA2 where it is unaffected by restraint stress or adrenalectomy. Neurol. Recent investigations into this area have not only delineated the CA2, but also defined it as a region distinct from both CA1 and CA3, with a unique set of cortical inputs and outputs and contributions to cognitive processes. Neuroscience research articles are provided. functioning. Neurosci. Social memory, the ability to recognize familiar conspecifics, is a complex biological process that enables stability of social interactions over time. The granule cells (stained with DAPI) make up the major cell type in the dentate gyrus. Young et al. One such process that has been shown to depend on the CA2 is the ability to recognize a novel or familiar conspecific, known as social recognition memory. J. Neurosci. They injected a Cre-dependent AAV into the dorsal hippocampus to express tetanus neurotoxin (TeNT) light chain in CA2 pyramidal neurons, which blocked neurotransmission. 34, 3056–3066. Rev. You may not alter the images provided, other than to crop them to size. Proc. Clinical and radiological findings in six additional patients. Pyramidal cell layers in the CA1 are more tightly packed than those in the CA2 and CA3 regions (Figure 3). CA2 neurons receive direct innervation from the lateral entorhinal cortex (LEC) via the temporoammonic pathway (blue). These chunks of memory are encoded separately from the neural code that stores detailed memories of a specific experience. They concluded that RGS14 regulates signaling pathways linking synaptic plasticity in CA2 to hippocampal-dependent memory processes, distinct from the trisynaptic pathway (Lee et al., 2010). In the CA2 and CA3 regions, the stratum lacunosum-moleculare receives inputs from layers II and VI of the entorhinal cortex, while the stratum lacunosum-moleculare in the CA1 receives input from layers III and V of the entorhinal cortex (Witter and Amaral, 1991; van Groen et al., 2003; Figure 4).

SP: stratum pyramidale. Neural activity in the ventral hippocampus corresponds to regions involved in emotion and stress (e.g., amygdala and hypothalamus). The researchers were also able to artificially link the memory of the familiar mouse with a positive or negative emotion. Under normal circumstances, mice prefer to interact with mice they haven’t seen before. doi: 10.1016/j.pneurobio.2004.09.003, Pitkanen, A., Pikkarainen, M., Nurminen, N., and Ylinen, A. The inputs from CA3 via Schaeffer collaterals amass a very large feedforward inhibition onto the CA2 neurons (Chevaleyre and Siegelbaum, 2010; Jones and McHugh, 2011). In addition to receiving input from cortical regions, layer V of the entorhinal cortex receives output from the CA1 via the subiculum, which then projects to other brain regions, such as the mamillary nuclei, the thalamus, and the nucleus accumbens (Amaral, 1993; Wible, 2013). doi: 10.1006/frne.2002.0229, Gilbert, P. E., Kesner, R. P., and Lee, I. The interdisciplinary field of social neuroscience studies how developmental, social, genetic, neural, and hormonal factors interact in shaping the everyday life of people. Induction of LTP was still absent when GABAA inhibitory currents were blocked using picrotoxin, yet all of these protocols consistently induced LTP in the CA1 (Zhao et al., 2007; Caruana et al., 2012).
