The Vestibular System - The Premotor Cortex

5 important questions on The Vestibular System - The Premotor Cortex

Upper motor neurons in the premotor cortex have a direct and an indirect pathway. Explain both.

The direct pathway contacts the lower motor neurons directly and the indirect pathway travels via the primary motor cortex.

What is the role of the premotor cortex?

It uses multisensory information from other cortices to select movements appropriate for the context

What special set of neurons located in the premotor cortex that discharge during observation of behavior?

Mirror motor neurons
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

What difficulties are associated with damage to the premotor cortex?

Difficulties selecting the appropriate motor action after receiving a external of internal cue/stimulus

What is the difference between the lateral and medial part of the premotor cortex with respect to movement selection?

The lateral part is responsible for the selection of movements as reaction on external (visual) cues. The medial part is considered with initiating movements by internal cues

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
