The Eternal Professors by David H. Keller:
Science Fiction Inventions, Technology and Ideas
"WITH apparatus that was definitely crude, Doctors Tchechulin and Brukhenenke, performed phenomenal experiments that proved almost miraculously successful, when they found that a head, severed from the body of a dog. was kept alive by means of a mechanical heart or by artificial circulation. Further tests showed that this severed head responded to certain stimuli in much the same manner that the head of a live dog would have re-acted to similar stimuli. This opens vistas of possibilities, for what might not be possible when this apparatus is perfected and progressive experiments have been made? In this story by Dr. Keller, who is not only a physician, but has a record of thirteen years of psychiatric practice behind him, also, we are allowed an absorbing glimpse into a vision of possible future achievements. We have often wondered how the individual's accumulated knowledge might be used."
