Abstract

Headholders are described for the cat, rat, squirrel, monkey, opossum and tree shrew which are relatively painless and minimize damage to the head. This type of headholder permits easy access to the head and various orientations of the head. It is stable enough for extracellular recordings of the electrical activity of CNS neurons. The general plan is to hold the head in a clamp bearing up on the upper hard palate or upper teeth, and down on the frontal bones or infra-orbital ridge. These headholders should be particularly useful in sensory experiments since the ear is not damaged by ear pins. They are easy to construct, and should be applicable to all mammals.

    A tracheal cannula was inserted to facilitate free breathing and body temperature was maintained at 37° with a circulating water heating pad. The rat head was immobilized using a nontraumatic head holder (Erickson, 1966). The left chorda tympani nerve (CT) was exposed laterally as it exited the tympanic bulla.

    Briefly, 14–30-day-old Sprague–Dawley rats (Charles River) were anesthetized with an intraperitoneal injection of a mixture of ketamine and xylazine (10 mg/kg each). The rat's head was fixed by an atraumatic holder (Erickson, 1966) and body temperature maintained by a heating pad. To label the CT nerve, a longitude incision was made in the midline of the neck and the tympanic bulla exposed.

    The animal was then tracheotomized to prevent stimuli from entering the lungs. A non-traumatic headholder was then used to position the animal (Erickson, 1966). The left zygomatic arch was removed and the left mandible was retracted.
