内容简介
数学书籍
Self-organization and Pattern-formation in Neuronal Systems Under Condi-tions of Variable Gravity Life Sciences Under Space Conditions describes the interaction of gravity with neuronal systems. To deliver the basic scientific and technological background, the structures of neuronal systems are described and platforms for gravity research are presented. The book is rounded off by information about the interaction of chemical model systems with gravity and some simulations, and results about the interaction of gravity with neuronal systems from single molecules to the entire human brain are demonstrated. This is the first book to give a complete overview about neurophysiological research under conditions of variable gravity.
The book is intended for scientists in the field of space research, neurophysiology,and those who are interested in the control of non-linear systems by small external forces.

书摘
The next set of experiments which has to be taken into account then is those with spontaneously spiking neurons. A prediction from the above statements (speculations) would be that in this case the spike frequency should be higher at microgravity. Just that has been shown. Also, a direct measurement of membrane potential should result in less negative values. In the experiments utilizing voltage sensitive dyes accurately this has been shown. According to textbook knowledge (Hille, 1992), at depolarization of membrane potential, voltage sensitive calcium channels open in the cell membrane, calcium enters the cell, and the intracellular calcium concentration increases. This could not be verified, in some experiments instead it was shown that the intracellular calcium level at microgravity drops (see above). As the intracellular calcium concentration is a highly regulated value, this could be due to secondary effects, but will have again to be investigated more deeply.
