Detection latencies of X and Y type cells of the cat's dorsal lateral geniculate nucleus.

abstract：:Descending vestibular pathways have been shown to influence recruitment thresholds of alpha motoneurones in both human and cat. However, whereas parallel connections to the fusimotor system have been shown in the cat, such connections have not yet been demonstrated in humans. In the present study we investigated wheth...
