1. In the rat striatum, glutaminase-like immunoreactivity was found in non-cholinergic neurons. Axon terminals containing glutaminase were observed with mosaic patterns; glutaminase immunoreactivity in neuropil was more marked in the "patches" than in the "matrix".2. In the neo- and mesocortex of the rat, glutaminase-like immunoreactivity was found in pyramidal cells, but not in most GABAergic, cholinergic and peptidergic nonpyramidal cells.3. Distributions of the mRNAs for metabotropic glutamate receptors, mGluRu and mG1uR2, were examined in the rat brain by in situ hybridization.4. The projections from the ventral tegumental area to the cerebellum in the rat were found to be segregated into the dopaminergic projections to the cerebellar cortex and the non-dopaminergic projections to the deep cerebeallr nuclei.5. The central amygdaloid nucleus of the cat was found to send projection fibers to the globus pallidus and substantia nigra pars compacta, possibly exerting limbic influences upon forebrain motor mechanisms.

1。在大鼠纹状体中，在非胆碱能神经元中发现了谷氨酰胺酶样免疫反应性。用镶嵌图观察到含有谷氨酰胺酶的轴突末端。在“斑块”中，谷氨酰胺酶的免疫反应比“基质”更明显。在大鼠的新和中皮层中，在金字塔细胞中发现了谷氨酰胺酶样免疫反应性，但在大多数GABA能，胆碱能和肽基型非锥虫细胞中却没有发现。3。通过原位杂交在大鼠脑中检查了代谢型谷氨酸受体，mgluru和mg1ur2的mRNA的分布。4。发现从大鼠腹侧甲状腺腹侧到小脑的投影被隔离到小脑皮层的多巴胺能投影中，而非多巴胺能投射到深贝尔利核。5。发现猫的中央杏仁核核可将投影纤维发送到pallidus和黑质Nigra pars compacta，可能对前脑运动机制产生边缘影响。
