Mitochondria and mitochondrial enzymes. A comparative study of localization in the cat's brain stem.

The cytological distribution and the frequency of mitochondria in certain nuclei of the cat's brain stem was compared with the histochemical reactions for succinic dehydrogenase and cytochrome oxidase, which are known to be mitochondrial enzymes. The distribution of mitochondria was found to be identical with that of the above oxidative enzymes. The significance of these findings for the understanding of the regional chemistry and metabolism of the brain is indicated.

Noradrenaline and adrenaline in the rat brain during acute and chronic morphine administration and during withdrawal.

FOLLOWING the demonstration of a release of catecholamines by morphine from the brain stem of cats and dogs1, my interest became focused on the mechanism of this release and the possible role of brain catecholamines in the morphine abstinence syndrome. In many this syndrome is characterized by signs of autonomic activity, for example, tremor, piloerection, lachrymation, salivation, fever, excitement mydriasis2. The same symptoms can be induced experimentally by electrical stimulation of hypothalamic and limbic brain areas of various laboratory animals3 and chemically by interference with the brain-stem content of some biogenic amines4,5.

Influence of visual cortex on light impulses in the brain stem of the unanesthetized cat.

Summary.1. Stereotaxic explorations have been carried out in the brain stem of unanesthetized cats of the topography and latencies of responses to optic stimulation. In one series intact preparations have been used and in a second group animals with chronic bilateral ablation of the visual cortex.2. In both the intact and the ablated preparations, visual inipulses were found to have a wide‐spread distribution in the brain stem, a fact which, in principle, confirms the observations of others by the fact that afferent responses in “unspecific” regions are not unconditionally dependent upon the cortical projection area of the modality tested.3. In the ablated preparations it was possible to trace a central diencephalic pathway for light responses which coincides topographically with the thalamic reticular system as well as with recently demonstrated fiber systems in intralaminar parts of the thalamus. The latencies of responses along this pathway which was followed to the gyrus cinguli indicated a slow contluction velocity. This pathway could not be distinguished in the intact preparations.4. The latencies of the visuil brain stem responses in the intact preparatious were generally shorter than those in the ablated series. This observation has been interpreted as an effect of corticofugal influences from the visual cortex upon the brain stem.5. The results suggest that the visual cortex (in the cat) is capable of controlling events elicited by visual stimulation in other (phylogenetically older) parts of specific visual structures as well as in unspecific visual pathways of the brain stem.

Effects of chronic lesions in central cephalic brain stem of monkeys.

THERE has been shown to exist in the median cephalic portion of the brain stem of cats 1 and monkeys 2 an area comprising the midbrain tegmentum, the subthalamus and hypothalamus and the medial portion of the thalamus which subserves a specialized function in the response of the animal to sensory stimuli. This area can be readily excited by peripheral stimulation, such excitation, or that produced by direct stimulation with a probing electrode, arousing the sleeping animal to wakefulness and altering its electroencephalogram in a manner consistent with such a change. The evidence suggests that this activating system is of particular importance in initiating and maintaining an alert or attentive state in the animal, rendering it capable of reacting adaptively to stimuli in a way impossible in sleep. Lindsley and associates 3 have observed that lesions placed so as to destroy a significant portion of this area in cats were
