[Context-Dependent Oscillation in Frontal Cortical Areas].

The frontal lobe consists of motor and prefrontal cortices with correlated but hierarchically organized functions. Specifically, cellular activity and oscillations are highly context dependent. On the other hand, cortical oscillations are due to the dynamic balance between excitation and inhibition. Several types of inhibitory neurons play distinct functional roles. This chapter reviews oscillatory phenomena and neural activity in the frontal lobes, as well as the local circuits underlying different oscillatory modes.
