Responses of single units in the pontine nuclei of the cat to acoustic stimulation.
Auditory responses of single units in the pontine nuclei of the anaesthetized cat were studied electrophysiologically. Many units in the pontine nuclei, and in particular the dorsolateral pontine nucleus were strongly driven by the onset of auditory tonal stimuli in a broadly tuned manner. Most units were excited by stimulation of each ear and demonstrated binaural facilitation. Also, many pontine units responded to visual stimuli and some were bimodally active. These response properties are similar to those of units recorded in the cerebellar vermis which probably receives auditory and visual input from the pontine nuclei.
