Abstract

Orientation Columns In the brain's visual cortex, certain neurons respond to vertical lines and others to horizontal lines, with a range in between. Such orientation of neurons tends to be organized in columns reflecting similar responses, and the columns are organized in pinwheels representing the range of responses. Kaschube et al. (p. 1113 , published online 4 November; see the Perspective by Miller ) looked at the organization of orientation columns in diverse placental mammals and discovered a similarity of organizational principles.
