ON THE ROLE OF THALAMIC AND RETICULAR FORMATION UPON THE FREQUENCY RESPONSE ACTIVITIES OF THE GENERATOR OF EENCEPHALOGRAM AND MYOTONOGRAM
Abstract
Theoretical and experimental studies on the activities of nonspecific and specific projection systems hidden in the electroencephalogram were conducted from the standpoint of the random proc ess in a stochastic servosystem. It was verified that EEG activity (frequency response) is not only equivalent to the excitability cycle of an excitable system, but to an extension of the spectral sensitivity curve of the visual system and response area of the auditory system. Cerebral EEG activities were elicited by centro median and midbrain reticular stimulation of low frequency. A high frequency reticular stimula tion, by which electrocortical arousal was in duced in EEG, followed an inhibitory and aug mentative processes to reduce and enhance re spectively the flicker activity of low frequency. It was inferred from the above theoretical and experimental results that servomechanic roles of nonspecific and specific projection systems are capable of observing in the EEG activities. On the same roles in the descending reticular system, some theoretical and experimental evi dences were demonstrated in the myotonographic (MT) activity.
