Theta oscillations in dorsomedial frontal cortex (DMFC) are prominent signatures of cognitive control and error monitoring (Cavanagh and Frank, Trends Cogn. Sci., 2014; Cohen, Trends Neurosci., 2014). Yet, the neuronal mechanisms generating these signals remain uncertain. Here, we study whether neocortical pyramidal neurons alone can induce frontal theta during error monitoring by combining electrophysiological data and biophysical modeling. We recorded neuronal spiking and local field potentials (LFPs) across all layers of DMFC from two macaque monkeys performing a saccade countermanding stop
