title: Identification of a tecto-olivocerebellar path to posterior vermis in the cat.
abstract: Climbing fibre projections to posterior cerebellar vermis (lobule VII) activated from midbrain tegmentum and tectum were studied in chloralose anaesthetized cats. Only a medial, possibly bilateral, region of lobule VII was activated by fibres proceeding in a dorsal tegmental region, located within and dorsally to the red nucleus. The same area of lobule VII was also activated from tectum, in the deeper layers of superior colliculi at slightly longer latency. It was suggested that this represents a tecto-olivocerebellar pathway.
