The human visual system consists of a hierarchy of multiple cortical areas and it has been reported that a cortical region in the fusiform gyrus called the Fusiform Face Area, FFA, responds much more strongly to faces than to any other class of stimulus. Recent studies have also revealed that objects of visual expertise activate the FFA more strongly than non-expertise stimuli, and it was argued that the
right FFA is involved in expertise-specific rather than face-specific visual processing. According to these evidences, we propose a new biologically plausible computational model to illustrate face and car expertise effect on the gateway to the right FFA. In addition, there has been reported a difference in the onset latency of macaque infero temporal neural responses. This latter case is also considered in the proposed model, where faces are recognized in the first layer and in the second layer, a discrimination task between cars and other objects is
carried out.
