Dissociable roles of the central and basolateral amygdala in appetitive emotional learning
Abstract
The amygdala is considered to be a core component of the brain's fear system. Data from neuroimaging studies of normal volunteers and brain‐damaged patients perceiving emotional facial expressions, and studies of conditioned freezing in rats, all suggest a specific role for the amygdala in aversive motivation. However, the amygdala may also be critical for emotional processing in positive or appetitive settings. Using an appetitive Pavlovian approach procedure we show a theoretically important dissociation in the effects of excitotoxic lesions of the central nucleus and basolateral area of the amygdala, in the rat. Whilst central nucleus lesions impair appetitive Pavlovian conditioning, basolateral lesions do not. Together with other data, these results not only support the hypothesis that the amygdala is critical for appetitive as well as aversive learning, but are also consistent with amygdala subsystems subserving distinct aspects of emotional learning. Lesions of the dorsal or ventral subiculum were without effect on autoshaping, indicating the lack of involvement of hippocampal processing in this form of emotional behaviour and emphasizing further the neural specificity of the effects seen following central amygdala lesions.

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.
