aThis table summarizes the modular features of human area V2 revealed through anatomical methods. An alternating dense and pale stripelike pattern is revealed when V2 is processed for the visualization of cytochrome oxidase (CO). This anatomical feature allows for a comparison of the organization of human V2 with that of nonhuman primates. The length of these cytochrome oxidase stripes provides an anatomical marker for the width of area V2. The pattern ofimmunoreactivity for CAT-301-provides ameans for distinguishing the CAT-301-dense CO thick stripes from the CAT-301-pale CO thin stripes. V2 is also characterized by an array of myelin-dense stripes that may correspond to either the CO thin or thick stripes.

both areas V1 and V2. In V1, weaker binding is observed in layers IVC and V, whereas in V2 a high density of binding is observed in layer IV. Muscarinic, M2 receptors, visualized through the binding of [3H] pirenzepine, show a high density in layers II and III of both areas V1 and V2. A high density of receptors is seen in layer IVC of V1 and in layer IV of V2. Weaker binding is observed in layer V of area V1 and in layer VI of V2.

Adrenergic receptors also show a differential regional pattern between areas V1 and V2. Overall, a1 receptors have a higher mean density in area V2 than in V1. This uneven distribution is largely due to the high density of a1B receptors in area V2. The peak a1 density
