Preoptic Area
POA = multipolar and rapidly adapting NPY interneurons as well as a smaller proportion of PV and SST interneurons. While NPY interneurons are largely found in superficial layers of the cortex, POA derived PV and SST neuron primarily go to deep layers of cortex (these then contain MGE and POA neurons) POA are among earlyiest to be created.
