Stratigenesis in the optic tectum of developing chick embryos was investigated between the 4th and the 11th day of incubation. Stratification is achieved by successive emigration of cell contigents from the proliferative layer. In the opinion of the authors the main factor which determines this very regular cell migration would be a gradient of oxygen and of metabolites. The gradient has to appear in the wall of tectum due to its typical vascular network. Experiences with induced hypoxia or with selective damage of the proliferative layer strengthen the hypotesis of an oxygen gradient playing the role of a generally active epigenetic factor in the stratigenesis of the central nervous system. 相似文献

Parameters of variational chronoreflexometry variation curve of distribution were shown to correlate with the level of mental development in mentally retarded children. The borderline values of the CNS function condition's criteria were determined for both normal children and those mentally retarded. A feasibility of assessing the interhemisphere functional asymmetry by means o this particular method, was shown. 相似文献

For the first time, the [14C]deoxyglucose radioautographic technique has been successfully used to map physiological activity in cephalopod brains. In unilaterally blinded octopus and cuttlefish, the optic lobe of the deprived side showed a decreased uptake of the labelled tracer. This suggests that the uptake is related to functional activity. The potential of the [14C]deoxyglucose technique as a powerful tool in studying the functional organization of cephalopod brains is discussed. 相似文献

The effects of angiotensin II (ANG II) and bilateral nephrectomy on monoamine oxidase (MAO) activity were studied in rat hypothalamus and medulla oblongata. ANG II increased MAO activity in both central nervous system (CNS) regions. The fall of circulating ANG II caused by 48 h bilateral nephrectomy decreased the activity of the enzyme in the mentioned areas. The results showed that ANG II stimulates catecholamine metabolism in the CNS. 相似文献
