We found that the cortex, via cortico-lateral-amygdala somatostatin neurons (CLA-SOM), has a direct inhibitory influence on the output of the LA principal neurons. Our results define a CLA long-range inhibitory circuit (CLA-SOM inhibitory projections → LA principal neurons) underlying the control of spike timing/generation in LA and LA–AC projecting neurons, and attributes a specific function to a genetically defined type of cortical long-range GABAergic neurons in CLA communication. SIGNIFICANCE STATEMENT It is very well established that cortical auditory inputs to the lateral amygdala are exclusively excitatory and that cortico-amygdala neuronal activity has been shown to be involved in sound-driven aversive/fear behavior. Here, for the first time, we show that the lateral amygdala receives long-range GABAergic projection from the auditory cortex and these form direct monosynaptic inhibitory connections onto lateral amygdala principal neurons. Our results define a cellular
We hack the human brain, study metaphysics and apply quantum physics two areas that were not meant to be.
