....clear, partly owing to the difficulty of knowing which stimuli to use to probe the neural selectivity. Reports of preferred features of neurons in V4, the visual area preceding IT in the ventral pathway, vary depending on the set of stimuli used to probe responses, including cartesian gratings [9], polar and hyperbolic sinusoidal gratings [17] and contour features [43] In V2, a recent study [23] has reported preferences to complex stimuli such as arcs, intersecting lines and non cartesian gratings. Instead of probing neuronal tuning with a fixed set of stimuli, a set of studies [32, 57, ....
