Austen, Burton G. Current distribution in subcortical regions of the cat’s brain during electrosleep. In Reynolds, David V. and Anita Sjorberg (Eds), Neuroelectric Research. Springfield, Charles Thomas. 28:262-266, 1971.

Following up on earlier researchers who said that when the hypothalamus was electrically stimulated “natural sleep” resulted, the author stimulated the caudate nucleus and the preoptic region of the hypothalamus in 5 adult female cats. The stimulus was a 15 second train of rectangular pulses, each with a width of 0.3 mS, frequency of 5 Hz, and an amplitude of between 0.1 and 2 V. The resulting current density and distribution in the cats’ brain was discussed.
