The development of social familiarity in rodents depends predominantly on olfactory cues and can critically influence reproductive success. Researchers have operationally defined this memory by a reliable decrease in olfactory investigation in repeated or prolonged encounters with a conspecific. Brain oxytocin (OT) and vasopressin (AVP) seem to modulate a(More)
Whole-cell and extracellular recording techniques were used to examine local circuit inhibition in the CA1 region of the rat hippocampus in vitro. Activation, primarily of the recurrent inhibitory circuit by alvear stimulation, elicited an IPSP in pyramidal neurons that was dependent, in part, on NMDA receptor activation. Application of a tetanizing(More)
This study investigated the effects of different rearing conditions on neural and cognitive development of male rhesus monkeys (Macaca mulatta). Infants raised individually in a nursery from 2 to 12 months of age (NURSERY, n=9) were compared to age-matched infants raised in a semi-naturalistic, social environment (CONTROL, n=11). Various brain regions were(More)
Previous studies have shown that oxytocin (OT)-deficient female mice produced by homologous recombination fail to lactate but exhibit normal parturition and reproductive behaviors. We examined the ultrasonic vocalizations of infant mice and the subsequent aggressive and fear behavior of adult male OT knockout (OT-KO) mice. Infant OT-KO mice were less vocal(More)
