Summary:
Investigation of the input?output structures of cortical circuits is necessary to clarify their dynamical properties. However, conventional physiological studies have focused primarily on spiking activity, which reflects the output of neurons or neuronal circuits. Recently developed multicontact electrodes enable the evaluation of synaptic inputs through current source density (CSD) analysis of local field potentials (LFPs) in addition to recording spikes. Here, we present preliminary findings of CSD patterns in the prefrontal cortex (PFC) of a behaving monkey and provide examples of how PFC neurons change their firing properties dynamically depending on input to PFC local circuits.
