Thalamus geniculate nucleus/lateral principal GLU cellDistal equivalent dendritemGluRCorticogeniculate input (T)Unlike the retinogeniculate input, the corticogeniculate input is received by both ionotropic and metabotropic glutamate receptors (McCormick DA and von Krosigk M, 1992 [guinea pig]1 ). SOBIV p316).A study indicates that synaptic activation of these receptors increases inhibitory activity in relay neurons by increasing output of presynaptic dendrites (Govindaiah and Cox CL, 20042 ).
