Comparison of the Effects of Bilateral Orbital Prefrontal Cortex Lesions and Amygdala Lesions on Emotional Responses in Rhesus Monkeys
Open accessAbstract
The present study examines the effects of bilateral orbital prefrontal cortex (PFo) lesions on monkeys' emotional responses in two different contexts: in the presence of a rubber snake and in the presence of a human intruder. For comparison, we also assessed the responses of rhesus monkeys with selective amygdala lesions on these same tasks. Monkeys with PFo lesions, like those with amygdala lesions, displayed blunted emotional responses to the fake snake. Unlike monkeys with amygdala lesions, however, monkeys with PFo lesions displayed more mild aggression than controls in the presence of a human intruder. The findings support the idea that the PFo helps integrate sensory signals in the service of choosing among competing responses. In addition, they point to a divergence of the roles of the PFo and amygdala in responding to a social stimulus, the human intruder.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
