Description
Summary:While object recognition typically feels effortless, it is one of the most computationally impressive feats performed by the human visual system. Due to its importance as an end stage of visual processing, a great deal of research has focused on characterizing those regions of the brain responsible for representing object categories. Congruent with research in monkeys, regions of the ventral visual pathway in humans are category-selective. Compared with the large number of possible object categories, the number of anatomically distinct regions with specific category selectivity is limited. Recent advances in neuro imaging methods such as multivoxel pattern analysis (MVPA) have revealed a more complex and distributed neural architecture of category selectivity in the ventral stream (Haxby et al., 2001; Carlson et al., 2003; Kriegeskorte et al., 2008).
