Identification of nocifensor reflex-related neurons in the rostroventromedial medulla of decerebrated rats.
Extracellular single unit recordings were made from neurons in the rostroventromedial medulla of decerebrated rats. The previously described 'on-cell' and 'off-cell' classes were found in this preparation, and this classification, which is based on tail flick-related changes in activity, was not altered by the introduction or removal of halothane anesthesia. It is therefore evident that the identifying physiological properties of on- and off-cells are not dependent on the presence of anesthesia in decerebrate rats, or on brain structures rostral to the inferior colliculi.
