Cover picture: A computer-rendered right hemisphere looking at a slant rivalry stimulus. The image is rendered such that when viewed with analglyphic filters (i.e., a red filter in front of the left eye and a green filter in front of the right eye), stereoscopic depth is perceived. See article by Brouwer et all. for details (pages 10403–10413). This cover image may also be viewed in 3-D at www.jneurosci.org/content/vol25/issue45 with analglyphic glasses. For a set of analglyphic glasses, print subscribers may send a self-addressed, stamped envelope to the Journal Central Office. Anaglyphic glasses available while supplies last.
