[State of the mitochondria and nuclear chromatin in cerebral cortex nerve cells during laser irradiation].

Effect of laser irradiation (PPM-mv/cm2, gamma = 632.8 nm) on respiratory and phosphorylating activities of mitochondria as well as on structure-functional state of nuclear chromatin from rat brain cortex neurones were studied. The irradiation stimulated the activities studied suggesting possible increase in functional potentialities of brain tissue under these experimental conditions.
