Distribution of the GABA_A receptor subunit immunoreactivities (α1–α5, β1–β3, γ1, γ2 and δ) in the amygdala (coronal sections of the mouse brain approximately Bregma −1.58 mm, according to Franklin and Paxinos, 2007). Scale bar = 500 μm. In the bottom right a schematic drawing adapted from Franklin and Paxinos, 2007 is included. CEA = central amygdala, BLA = basolateral amygdala, I = intercalated nucleus, MA = medial amygdaloid nucleus. The distribution of the subunits protein very well agrees with that of the mRNA with, e.g. no or only faint immunoreactivity for the subunits α1, β2 and γ2, but a relatively strong labeling for subunit γ1 in the central amygdala.
