title: Topographical arrangements of feline motor cortical projections onto the pretectum.
abstract: The projections from motor cortex to pretectum were traced autoradiographically in 15 cats aimed at revealing a topographical arrangement. The anterior sigmoid and rostral coronal gyrus projected amply onto the ventrolateral part of the nucleus pretectalis anterior and to a large part of the ventrocaudal part of the nucleus pretectalis posterior. The posterior sigmoid gyrus rostral to the postcruciate dimple and the caudal part of the coronal gyrus also projected to the nucleus pretectalis anterior. In the posterior pretectal nucleus their target areas were smaller and located more ventromedially. The strongest projections originated from the coronal gyrus.
