Calbindin immunoreactivity alternates with cytochrome c-oxidase-rich zones in some layers of the primate visual cortex.

Calcium ions have a pivotal role in many neuronal activities, but little is known about their involvement in the cortical processing of visual information. Using immunohistochemical methods, we have now detected a calcium-binding protein, calbindin-D-28K, which may confer on certain compartments of cortical area 17 the ability to modulate Ca2+ metabolism. Thus, calbindin occurs in the primate striate cortex in a pattern almost complementary to that displaying strong cytochrome c-oxidase activity. From this and other observations, we deduce that the distribution of calbindin-immunoreactive sites corresponds mainly to extra-geniculocortical connections of the primary visual cortex. This implies that the geniculocortical and extra-geniculocortical compartments of area 17 differ in an intracellular system for Ca2+ homeostasis.[1]
