Figure 3:
The BLA receives and integrates sensory inputs from the thalamus and cortical regions, subsequently projecting to the lateral division of the central amygdala (CeL) to modulate fear expression levels. During fear learning, auditory stimuli enhance the activity of parvalbumin-positive (PV) neurons while suppressing somatostatin-expressing (SST) neurons. Both PV and SST neurons regulate fear output by inhibiting dendritic excitatory neurotransmission in the BLA during conditioned stimulus (CS) presentation, thereby controlling BLA-to-CeL projections and fine-tuning fear expression.
