Topographic Patterns of Hippocampal Theta Rhythm in Freely Moving Rat and Rabbit

Part of the Advances in Behavioral Biology book series (ABBI, volume 20)


In 1954 Green and Arduini (13) reported the presence of approximately sinusoidal, high-amplitude, slow waves of 3–7 cps in the hippocampus of both curarized and freely moving rabbits. In the curarized rabbit, the slow waves appeared in response to natural sensory stimulation of electrical stimulation of certain subcortical structures. The waves appeared in the freely moving animal when it was alert and interested in its surroundings. The hippocampal slow waves were termed theta rhythm in keeping with the designation that had previously been established for human EEG components in the 4–7 cps frequency range, and the theta rhythm was characterized as an arousal reaction of the hippocampus.
