Subcircuit-specific neuromodulation in the prefrontal cortex
... PT and IT neurons in PFC also express different active properties. IT neurons have a lower threshold for action potential initiation, and greater action potential half-width than PT neurons (Dembrow et al., 2010). These differences are also observed in anaesthetized animals in vivo (Cowan and Wilson ...
