Question

Which of the following is NOT a common feature of the cortical layers?

A. There is a primary source of input and primary output target
B. Cells with similar functions tend to be arrayed in columns that span all cortical areas, and receive inputs that are segregated into radial bands
C. Interneurons give rise to extensive local axons that extend horizontally
D. Connections in the vertical axis are columnar connections
E. Connections in the horizontal axis are radial

Answer 1

The cortical layers do not have radial connections in the horizontal axis.

Step-by-step explanation:

Connections in the horizontal axis are radial is NOT a common feature of the cortical layers. In the cerebral cortex, cells with similar functions tend to be arrayed in columns that span all cortical areas, and receive inputs that are segregated into radial bands. Interneurons give rise to extensive local axons that extend horizontally, and connections in the vertical axis are columnar connections.
