Abstract
Spontaneous oscillatory electrical activity in the human brain at a frequency near 40-Hz and its reset within thalamo-cortical systems by sensory stimulation has been proposed earlier [1–3] and has been suggested to be related to cognitive processing and to the temporal binding of sensory stimuli [3,4]. In particular, we demonstrated spontaneous 40-Hz coherent magnetic activity in the awake and in REM sleep states that is reduced during delta sleep [3]. This 40-Hz magnetic oscillation has been shown to be reset by sensory stimuli only in the awake state but not during REM or delta sleep. Because spontaneous 40-Hz oscillation was seen in wakefulness and in dreaming, we proposed it as a correlate of cognition, probably resultant from coherent 40-Hz resonance between thalamocortical specific and nonspecific loops [3].
