k cell การใช้

• This suggests that K cells act like other thalamocortical cells.
• K cells are not restricted to the koniocellular layers.
• Unlike M and P cells, K cells are structurally similar to other thalamocortical neurons.
• Moreover, K cells innervate extrastriate areas.
• K cells differ in their size from M and P cells, they are much smaller.
• These K cells are rather large, sending their axons to V2 and inferotemporal cortex ( IT ).
• The fact that K cells directly project to hMT supports this hypothesis ( see below  theory of blindsight ).
• In between the six layers are smaller cells that receive information from the K cells ( color ) in the retina.
• Corticogeniculate axons appear to be quantitatively dominant within the LGN . The same holds for K cells but unlike M and P cells they also receive input from the extrastriate cortex.
• Gastric inhibitory polypeptide ( GIP ), also called glucose-dependent insulinotropic polypeptide, is a 42-amino acid polypeptide synthesized by K cells of the duodenum and small intestine.
• Immunostaining revealed only a few, sparse and broadly distributed large K cells, apart from the K cells innervating the foveal representation of V2 which are more densely packed and found along the caudal and medial margin of the LGN . Throughout each K layer there are neurons that innervate the extrastriate cortex and that are likely to sustain some visual behaviors in the absence of V1.
