Abstract
EEG activity in the 35--85 c/sec range has been reported from the rhinencephalon of
numerous species of homeotherms, and from numerous parts of the forebrain in carnivores
and primates, including man. Unimodal distributions of frequencies within this range
for each of 3 species (cat, rat and rabbit) are reported here with proportionality
between means and variances. Theoretical analysis has shown that the basis for this
oscillatory activity lies in the feedback synaptic interactions of assemblies of excitatory
and inhibitory neurons, and that there is a neural basis for frequency convergence
and high amplitude near 40 c/sec. Given the synaptic mechanisms, the unimodal spectral
distributions, and the widespread occurrence of EEG activity in this range, it clearly
represents a unique and identifiable form of brain activity.
