[The molecular cellular mechanisms of the protective effect of short-term anoxia]

Recovery of unit activity was studied after a 5-min anoxia following a short-term anoxia in the cat brain cortex. The short-term anoxia's protective effect was only revealed in case when it had induced the phenomenon of asphyxic hyperactivity. The protective effect seems to be due to the short-term anoxia-induced changes in the calcium, polyphosphoinositide and cAMP regulatory systems' activity.
