Koniocellular Cell

A koniocellular cell (K-cell) is a neuron whose cell body is located in the koniocellular layer of the lateral geniculate nucleus in primates, including humans. The koniocellular cells receive their input from bistratified retinal ganglion cells exiting the optic tract, and send their information via relay neurons in the optic radiation to the primary visual cortex. The koniocellular layers are located between the magnocellular and parvocellular layers, in thin interlaminar regions of the LGN. As part of a general pattern, K neurons form robust layers through the full representation of the visual hemifield.
