Effects Of Pre-Pubertal Social Experiences On The Responsiveness Of Juvenile Rats To Predator Odors, Stephen M. Siviy
Effects Of Pre-Pubertal Social Experiences On The Responsiveness Of Juvenile Rats To Predator Odors, Stephen M. Siviy

The extent to which social variables may modulate the fear associated with a predator cue was assessed in juvenile rats. Cat odor reduced play to a comparable extent in both socially housed and isolate-housed rats, although socially housed rats exhibited more risk assessment during extinction. Rats that had played previously in the context used for assessing fear hid slightly less when exposed to cat odor than those rats that had not played previously in the testing context. However, no other differences were found between these two groups suggesting that prior social experience with the testing context has minimal effects on …

Several lines of evidence implicate the amygdala in face-emotion processing, particularly for fearful facial expressions. Related findings suggest that face-emotion processing engages the amygdala within an interconnected circuitry that can be studied using a functional-connectivity approach. Past work also underscores important functional changes in the amygdala during development. Taken together, prior research on amygdala function and development reveals a need for more work examining developmental changes in the amygdala’s response to fearful faces and in amygdala functional connectivity during face processing. The present study used event-related functional magnetic resonance imaging to compare 31 adolescents (9–17 years old) and 30 adults …
