Social memory

The dorsal and ventral hippocampus is involved in the formation of social memory (van Wimersma Greidanus and Maigret, 1996). Neonatal ablations of hippocampal regions can lead to decreased and abnormal social behavior in rhesus monkeys that is reminiscent of severe neuropsychiatric disorders in humans such as autism and schizophrenia (Bachevalier et ah, 1999). These monkeys are often withdrawn socially and will develop locomotoric stereotypies a pattern similar to that found in autistic children. 

Oxytocin typically has a facilitative effect on affiliative behaviors (Witt et ah, 1992), including parental and reproductive behaviors and infant-mother attachment. Oxytocin facilitates social memory, with knockout mice displaying social memory deficits it facilitates conditioning to maternal-related olfactory cues (Nelson and Panksepp, 1996). 

Arginine-vasopressin, a nine amino acid peptide, facilitates the formation of social recognition and social memory in rats, and AVP antagonists block such facilitation (Winslow et ah, 1993). It has been suggested...

Fig. 12. Effects of scopolamine on social recognition memory in the rat. Note the clear decrease in social investigation in the vehicle control group between the first and the second exposure 30 minutes later (social memory) and the absence of effect of scopolamine on social investigation during the first exposure (absence of intrinsic effects of scopolamine on social investigation). In the scopolamine-treated animals there is no decrease in social investigation at the second exposure, demonstrating impairment of social memory.

Oxytocin is a neuropeptide synthesized in the paraventricular and supraoptic nucleus of the hypothalamus. Oxytocin is released from axon terminals of the posterior pituitary into the bloodstream. It is also distributed to the central nervous system and oxytocin binding sites are found throughout, especially in the limbic system (Insel and Young, 2000). Oxytocin has been linked to afifiliative behavior, social memory, and behavior, all of which are impaired in autism (Insel et al., 1999). It has been hypothesized that dysfunction of oxytocin and vasopresin contributes to social impairment in autism (Waterhouse et al., 1996). 

Animal models have shown that oxytocin plays a role in social recognition (Popik et al., 1992) and that oxytocin antagonists disrupt social memory (Engelmann et al.,...
