Is prefrontal cortex hierarchically organized?

The lateral prefrontal cortex (LPFC) plays essential roles in cognition. In macaque, LPFC occupies large cortical areas anterior to the arcuate sulcus, and dorsal and ventral to the principal sulcus (PS). Despite many decades of research, functional differentiation within LPFC remains largely unknown. In monkeys, few attempts have been made to characterize neural activities in the anterior part of LPFC including frontopolar PFC (FP-PFC). In this seminar, I will present findings from our recent neurophysiology experiment that investigated spiking and LFP activities across entire anterior-posterior extent of LPFC in 8 different cognitive tasks.
