 Hippocampal theta rhythm is probably the best example of oscillations and synchrony phenomena occurring in neuronal networks of the central nervous system. It is well known that intraneuronal communication via chemical and electrical synapses underlies these oscillatory processes. Despite well-documented knowledge concerning the participation of chemical transmission in production of theta activity, the role of much faster gap junction communication is still not fully understood. This paper provides an overview of current research data concerning the involvement of electrical transmission in generation of the best synchronized EEG pattern recorded from the mammalian brain – theta rhythm.
