The amygdala integrates emotion, sensory information, logical thought, and mnemonic outputs of the cortex and basal forbrain. It is activated while animals feel fear or affection, and fight or flight against upcoming threatening. It projects to the mediodorsal nucleus of the thalamus and alternates activities of the prefrontal cortex. It also projects to the hypothalamus, and regulates the visceromotor function and hormonal regulations. However, the relationship between the amygdala and the sensory systems is not yet clearly understood. We here focus on emotional regulations of sensory processing through projections from the amygdala to the mesencephalic trigeminal nucleus.
