LIGHT-MICROSCOPIC COMPARISON OF THE PATTERNS OF GLUTAMATE-LIKE AND HOMOCYSTEATE-LIKE IMMUNOREACTIVITIES IN RAT DORSAL LATERAL GENICULATE AFTER COMBINED VISUAL CORTICAL ACID RETINAL ABLATIONS

To study the contribution of retinal and cortical afferents to the pat terns of glutamate- and homocysteate-like immunoreactivities in dorsal lateral geniculate, combined retinal and cortical ablations were perf ormed in rats. In controls, glutamate immunoreactivity was in terminal -like dots and neurons. Homocysteate immunoreactivity was in small pun cta. In lesioned animals, most glutamate-immunoreactive dots disappear ed. In contrast, abundant puncta resembling parts of glial cells were immunoreactive for homocysteate.
