[The effect of microwaves on the neuronal activity of the hyperstriatum in chick embryos at the critical developmental period].
Studies have been made on multineuronal activity in the dorsal hyperstriatum of chick embryos exposed to microwave radiation (2.375 MHz) at critical stage of development of the structure (19th day of incubation). One day after microwave exposition, activation of neurones was observed in a form of the increase in the discharge frequency and the increase of outburst form of the activity. Cyclic form of outburst activity was absent in experimental animals being present in control embryos of the same age and associated presumably with self-organization of microsystems of neurones in the developing brain. Changes in multineuronal activity were found only in the left hyperstriatum, which is probably due to different levels of the development and functional activity of the right and left hyperstriatum at this stage resulting from asymmetric intensity of visual afferentation which depends on the position of embryo inside the egg.
