[In cats, we performed brief circumscribed surface cooling of the somatosensory area and examined changes in the evoked potentials. 1. After intensive cooling, the waves of the primary complex disappeared and only the irradiance potential with unchanged latency was detected. 2. 3. Our experiments with cooling suggest that other mechanisms besides the function of the more superficial cells of the cortex are involved in the generation of the negative wave of the primary complex. 4. The surface-positive afterglow of cooling can be interpreted as an irradiance wave of extralemniscal polysynaptic afferentatio. 5. A spreading depression state may occur during local cooling of the cortex. 6. By 30 sec of ice cooling, the evoked potentials disappear completely, but the impairment of cell function is always reversible. Restitution of the primary complex waves occurs in 3- 4 min. In addition to the extent of cooling, the rate of cooling also plays a significant role in the change in induced potentials. ]
[1. Authors describe two cases of psychotherapeutic treatment with psychotropic drugs in psychoneurotic patients. 2. They present their cases as a model of the change in psychic dynamics during drug exposure. 3. They explain the relationship between drug-induced imagery and pathological experiences. 4. They suggest that psychodysleptics can be used to shorten psychotherapeutic treatment and make it more effective. 5. They see the therapeutic effect in facilitating the identification of the associative relationship between current and past psychotraumas, and in the cathartic re-enactment and discussion of the associated affect.]
[Morphological features of brain capillaries from one-, six- and nine-day-old mice were studied by electron microscopy. The endothelial layer is complete and continuous, the endothelial-cell junctional interfaces are well developed, and the zonula occludens is characteristic. The endothelial layer is thus identical in all essential features to that found in adulthood. The basement membrane, on the other hand, is poorly developed, but its density increases with age. There are significant extracellular gaps between the perivascular and neuropil elements in the neonatal animal; these gaps gradually decrease in extent. In the neonate there is no perivascular asrtocyte sheath, but the formation of this structure begins early and progresses steadily, although it is incomplete at nine days of age. These morphological features of the immature central nervous system provide an opportunity to interpret certain phenomena of the blood-brain barrier.]
