Hierarchical processing refer to processing signals through a sequence of areas. This occurs in the visual system as signals are transmitted from the LGN to the primary visual receiving area and then to higher areas. It occurs in the auditory system as signals are transmitted from the core to the belt to the parabelt regions of the cortex.
