Vibrissa-responsive neurons of the superior colliculus that project to the intralaminar thalamus of the rat.
Responses to deflection of vibrissae were studied in neurons of the superior colliculus projecting to the intralaminar thalamus. Forty-two percent were activated by deflection of several vibrissae. Some units showed habituation and directional sensitivity but no other feature extraction was noted. All responsive units were located in the intermediate and deep layers in a roughly somatotopic distribution and intermingled with other projecting and non-projecting units.
