نقش دیفرانسیل آمیگدال باسالئال و هسته بریسال ماکوسولولاریس در طی بازسازی ترس متعارف در موش صحرایی

Basolateral amygdala inactivation disrupts the contextual fear response and its generalization but not acoustic CS trace retention, when measured 72 and 96 h after tetrodotoxin administration. Nucleus basalis magnocellularis functional inactivation does not affect memory post-reactivation phase of any of the three conditioned fear responses. The present findings show a differential role of the two structures in fear memory reconsolidation and can be a starting point for future investigation of the neural circuits subserving generalization.
