The fact that the planum temporale region activates to non-auditory stimulation (eg, during silent lip reading (calvert et al, 1997)) is consistent with this characterization on this view, posterior parietal regions, extending down into the dorsal most aspect of the posterior temporal lobe, contain systems critical for interfacing sensory . Activation of auditory cortex without auditory input was reported during silent lipreading (calvert et al, 1997) and the observation of articulatory gestures (pekkola et al, 2005) similar mechanisms may underlie the activation of the primary auditory cortex in the present study.
