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 basis for…

The untouchables: 7 foods to avoid at all costsNaveed Saleh, MD, MS, for MDLinx | August 23, 2019
Many people consider themselves food experts. After all, we’ve all been eating food for our whole lives, haven’t we? But there are certain foods that are unhealthy, and it’s not always obvious which ones they are.
