The amygdala performs a primary role in emotional behavior and learning. The lateral nucleus of the amygdala (LA) is a key site of plasticity of fear learning, and inhibitory GABAergic circuits in the LA play an important role in the regulation of fear memory and its extinction by controlling projection neuron activities. GABAergic neurons in the LA, like the cerebral cortex, are morphologically, connectionally, electrically and chemically heterogeneous. However, little is know how each subclass of GABAergic neurons serves its functions for amygdaloid circuits. Here we provide the immunohistochemical characterization of calcium-binding protein (parvalbumin, calretinin and calbindin-D28k)-containing GABAergic neurons in the LA , using vesicular GABA transporter (VGAT)-Venus transgenic mice, in which GABAergic neurons are labeled with Venus fluorescent protein. Our results suggest that each subclass of calcium-binding protein-containing GABAergic neurons in the LA might have unique properties for regulating amygdaloid functions.
