Abstract:
The effect of asymmetrical levels of cutaneous afferent activity (CAA) on the performance of a bilaterally conditioned nictitating membrane response in New Zealand albino rabbits was investigated. Afferent activity levels were controlled by varying US locus, corneal applications of a local anesthetic (0.5% tetracaine hydrochloride) and by exerting mechanical tension on the eyelids. Performance of the response in each eye was controlled independently of the response levels concurrently attained by the contralateral eye. Appropriate tests suggested that the two eyes do not function independently in learning, regardless of the disparity in CAA level between them, due to central transfer.
Keywords:Bilateral conditioning  Cutaneous afferent activity  Nictitating membrane
