title: Radioautographic identification of [3H]glutamic acid labeled nerve endings in the cat oculomotor nucleus.
abstract: Slices of the cat third oculomotor nucleus were incubated in vitro with [3H]glutamic acid. Electron microscopic radioautographs revealed that glutamate had been taken by small nerve endings distributed on the oculomotor motoneuron distal dendrites. In contrast, there was no uptake in the other types of terminals. The labeled terminals seem to correspond to the excitatory vestibulo-oculomotor nerve endings and different correlations suggest their glutamergic nature.
