[Spectral analysis of the effects of nomifensine on bioelectric activity of the rat brain].
The influence of nomifensine on bioelectrical activity of sensorimotor cortex, dorsal hippocamp and lateral hypothalamus in conscious rats in free behavior was studied. The pharmacological and EEG analysis of nomifensine action on EEG power spectra by Fourier technique was measured. It was established that nomifensine evoked an increase and stabilization of the dominant peak in EEG spectra in the left and right cortex and in the left hippocamp, while in the other ranges of frequency a decrease was observed. The effects on hypothalamus was opposite--EEG power spectra decreased in all the ranges. The authors conclude that nomifensine evokes higher level of wakefulness, vigilance of the animals. This is likely to underlie neurophysiological mechanisms of optimal behavior due to stimulants of CNS, including nomifensine.
