Lecture 10 - Cerebellum - Quiz 1/2 Flashcards
T/F - The cerebellum participates in adaptive control in the motor system
True
T/F - The cerebellum participates in the evaluation of differences between intention and action within the motor system
True
T/F - The cerebellum participates in motor learning
True
T/F - Lateral cerebellar lesions affect sequential rather than coordinated movement
True
T/F - Neurons in the dentate nucleus may fire approximately 100ms before movement
True
T/F - The lateral cerebellar cortex receives input from the premotor cortex and projects through the dentate nucleus and thalamus back to the premotor cortex
True
