Voluntary Motion Flashcards
What information does the V6A and PEc receive? What lobe are these areas located on?
Receives visual information
Parietal lobe (cortex)
What does the ventral intraparietal(VIP) area do? What action is it involved in?
Creates a rough map of space around you
Reaching
What region of the brain is the F4 located in? What action is it associated with?
Premotor cortex
Reaching
How does the F4 region create a detailed map of the space around you?
Neurons in F4 are excited by proximity (more activity the closer an object is)
What information does the superior parietal cortex receive?
Visual information about where your arm is in space
What region in the brain would generate a map of the location of your arm in relationship to your body and the things around you?
F2
What actions are the anterior intraparietal area and PFG responsive to?
Seeing an object and grasping it
The F5 region receives information from what region of the brain?
PFG/Anterior intraparietal area
When do neurons in the F5 region fire?
With the goal of the action (Intended goal: to drink the tea, how it is held is not important)
What is the visual pathway required for reaching and grasping?
Dorsal visual pathway
What motor cortex receives sensory information required to move and determines the appropriate motion and intent of the motion?
Premotor cortex
What is the supplementary motor area of the supplementary motor cortex involved in?
Postural control
What is the pre-supplementary area of the supplementary motor cortex involved in?
Plans motor program required to make the action occur
What is the function of the supplementary motor cortex?
Organize motor sequences
Acquire motor skills (with cerebellum)
Executive control (decision to switch actions/strategies)
Axons from what cortical layer become the upper motor neurons?
Layer V
