middle gray layer of the superior colliculus
Acronym: SCmg

The term middle gray layer of the superior colliculus refers to the fourth outermost layer of the seven-layered superior colliculus of primates and rodents. Identified by internal structure, it is located between the superficial white layer of the superior colliculus and the middle white layer of the superior colliculus. The remaining layers are the deep gray layer of the superior colliculus and the deep white layer of the superior colliculus ( Carpenter-1983 ). Functionally it is part of the motor superior colliculus in the subcortical motor system ( Swanson-2004 ). In the rat the middle gray layer is further divided into sublayers a, b, and c.
