Layers
Similar in physiology and connectivity to W cells in cat lateral geniculate nucleus, K cells form three pairs of layers in macaques.
- The middle pair relays input from short-wavelength cones to the cytochrome-oxidase blobs of primary visual cortex (V1), .
- The dorsal-most pair relays low-acuity visual information to layer I of V1.
- The ventral-most pair appears closely tied to the function of the superior colliculus.
Throughout each K layer are neurons that innervate extrastriate cortex and that are likely to sustain some visual behaviors in the absence of V1.

Famous quotes containing the word layers:
“The force of a death should be enormous but how can you know what kind of man you’ve killed or who was the braver and stronger if you have to peer through layers of glass that deliver the image but obscure the meaning of the act? War has a conscience or it’s ordinary murder.”
—Don Delillo (b. 1926)
“I think it’s the real world. The people we’re writing about in professional sports, they’re suffering and living and dying and loving and trying to make their way through life just as the brick layers and politicians are.”
—Walter Wellesley (Red)
