Document Summary
Action systems used to understand the actions of others, control thought and. A basic cognitive framework for movement and action. Movements that occur in the absence of cognition are not considered actions. Degrees of freedom: how to act on an object: motor programs simplify problems. Actions directed towards perceived objects based on their position in space medium and our relation to them: sensory-motor transformation. Homunculus problem: least understood is the way goals, plans, and intentions are represented in the brain. The role of the frontal lobes in movement and action. Pmc responsible for all voluntary movements of the body: somatotopically organized. Hemiplegia: damage to one side of the motor cortex results in a failure to voluntarily move the other side of the body. Frontal eye fields determine voluntary movement of the eyes: other areas in cortex to action planning, eye movement guided primarily by external senses, skeletal-based movements rely more on info from position of the limbs.
