Simple stimuli included oriented bars and sinusoidal gratings; complex stimuli included angles, arcs, circles, and intersecting lines, plus hyperbolic and polar gratings. We found that most V2 cells responded well to at least some of the complex stimuli, and in many V2 cells the most effective complex stimulus elicited a significantly larger response than the most effective The neural mechanisms by which the visual cortex analyzes low-level spatial dimensions, such as orientation and spatial frequency, have been studied intensively (DeValois and DeValois, 1988; Reid and Alonso, 1996). In addition, selectivity for a variety of more complex shape characteristics has been reported in early},
