PMID-5941514[0] Feeding induced in cats by electrical stimulation of the brain stem.

  • tested in cats.
  • stimulation points in the lateral hypothalamus (makes sense, controlls hunger)
  • half in ventral tegmental area (VTA)
  • aphygia is induced by lesions of the lateral hypothalamus.
  • in one experiment, the meat in the bowl was replaced with a banana. "Upon stimulation the cat quickly approached the bowl, sniffed the banana, turned away (in some disgust and frustration!?), searched the chamber, returned to the banana etc, but would not eat the banana."
