Journal ArticleDOI
Amygdala-frontal interactions and reward expectancy.
TL;DR: Converging evidence from rodents, humans, and non-human primates indicates that interconnections between the basolateral complex of the amygdala and the orbitofrontal cortex are crucial to the formation and use of expectancies of reinforcers in the guidance of goal-directed behavior.
Journal ArticleDOI
The use of animal models to study the effects of aging on cognition
Michela Gallagher,Peter R. Rapp +1 more
TL;DR: The importance of animal models for understanding the effects of normal aging on the brain and cognitive functions and the neurobiological effects of aging that may account for alterations in psychological functions are addressed.
Journal ArticleDOI
Different roles for orbitofrontal cortex and basolateral amygdala in a reinforcer devaluation task.
Charles L. Pickens,Michael P. Saddoris,Barry Setlow,Michela Gallagher,Peter C. Holland,Geoffrey Schoenbaum +5 more
TL;DR: It is indicated that the OFC and BLA play different roles in mediating normal goal-directed performance in this, and likely other, settings, as the reinforcer devaluation paradigm indicates.
Journal ArticleDOI
Circuit-specific alterations in hippocampal synaptophysin immunoreactivity predict spatial learning impairment in aged rats.
TL;DR: These findings are the first to demonstrate that a circuit-specific pattern of variability in the connectional organization of the hippocampus is coupled to individual differences in the cognitive outcome of normal aging.
Journal ArticleDOI
The amygdala and emotion
TL;DR: The use of animal models has progressively defined the circuitry for these functions within the amygdala and its interconnections with other brain systems, including pathways through which the amygdala modulates memory and regulates attention.
