  • Abstract
  • Look Inside

Destruction of the ventromedial tegmentum (VMT) of the midbrain in monkeys is known to produce tre-mors similar to those seen in Parkinson's disease. To elucidate such tremorgenic mechanisms, 50% horseradish peroxidase (HRP ) was injected into the VMT target region in three monkeys (macaca fuscata fuscata ) and eleven adult cats. The volume injected varied between 0.05 and 0.1 microliter.

The results suggest that afferent fibers to the thala-mus, which passed through the VMT region, contains tractus cerebellothalamicus and nigrothalamic fibers.
