Oscillations of cortical areas in gamma frequencies has been extensively studied, however, distant cortical areas are able to synchronize in other ranges besides the gamma band. Local field potentials recorded from the frontal (F) and visual (V) cortical areas of a rat performing exploratory motor behavior (active state) and motor quiescent (passive state) present distinct features concerning to the zero-lag synchronization of the two cortical regions.
During the active state visual and frontal areas activate more coherently when compared to the passive state, as can be seen from a higher peak in the cross-correlogram shown in figure 1. The theta band synchronization of neuronal activity in the frontal and visual cortical regions can be explained by the dynamical relaying phenomenon in which the hippocampus is assumed to play the role of the mediating element.
