Chez le spermophile, la teneur en glutamine et en acide glutamique cérébral au cours du réveil du sommeil hivernal était inchangée. Pendant le réchauffement des animaux refroidis, la glutamine et GABA étaient remarquablement élevés.

IN an attempt to investigate the possible differential reactivity of various cerebral structures when exposed to the action of different brain region anti-sera, it has been shown that the injection of heterologous anti-caudate nucleus antibody into the lateral cerebral ventricle of the cat was followed by pronounced electrographic abnormalities, confined mainly to the caudate nucleus. Since the electrical activity of other, simultaneously investigated brain regions was not essentially modified, the alterations observed were interpreted as being strongly suggestive of the possibility that the anti-caudate antibody has an affinity for the homologous nervous tissue1.
