Key Concepts

Posterior Parietal Cortex

This region integrates multisensory information to create a spatial map, which is essential for guiding movements. It transforms visual, somatosensory, and proprioceptive inputs into signals that can be used to determine the position and movement of the body in space, allowing for accurate targeting and coordination during actions.

Prefrontal Cortex

The prefrontal cortex is involved in high-level executive functions such as decision-making, planning, and maintaining attention, which are critical for initiating and adapting movements. It helps in selecting appropriate motor responses by considering goals, context, and future consequences, thus linking cognitive processes with motor actions.

Premotor Cortex

This area contributes to the planning and preparation of movements by selecting and organizing motor actions based on external cues. It is responsible for formulating strategies for movement execution by integrating sensory information with motor plans, which leads to the production of appropriate responses to environmental stimuli.

Supplementary Motor Cortex

The supplementary motor cortex is key for internally generated movement sequences and the coordination of complex actions. It plays a role in organizing and timing sequences of movements, especially in tasks that require internally guided decisions and bimanual coordination, ensuring seamless execution of planned motor activities.
