The occurrence of serotonergic nerves in the bovine cornea.

abstract：:Repeated stimulation can lead to a decrement in the amplitude of a response, or its disappearance. This is known as habituation. Responses recorded in the reticular formation of the brain to peripherally applied stimuli tend to habituate. Decerebration considerably reduces the occurrence of this habituation and naloxo...
