Lecture 15: Advanced Models of Motor Control

These flashcards cover key concepts related to advanced models of motor control and the workings of the central nervous system (CNS) as discussed in the lecture.

CNS

Central Nervous System; responsible for planning, initiating, monitoring, and regulating motor skills.

Feedforward Control

A process in which the CNS uses sensory feedback to transform motor plans into motor commands.

Feedback Control

A regulatory process using sensory feedback from the body and environment to adjust ongoing movements.

Frontal Lobe

Region of the brain responsible for motor, speech, and cognitive functions.

Parietal Lobe

Brain region involved in somatosensory and visuospatial functions.

Temporal Lobe

Area of the brain linked to language, auditory, and visual functions.

Occipital Lobe

Part of the brain that is primarily associated with visual functions.

Hybrid Models

Advanced models incorporating features of both feedforward and feedback control using distributed networks of brain regions.

Multiple Network Models

Models that use different networks to plan, initiate, monitor, and regulate motor skills.

Affordance Competition Hypothesis

A theory that suggests two distinct brain networks for motor planning: a selection network and a specification network.

Inverse Internal Models

Models that use efference copies of motor plans to regulate movements through predictive feedback mechanisms.

Forward Internal Models

Models that utilize efference copies of motor commands to predict sensory feedback and regulate movements.

Optimal Feedback Control

Proposes that motor skills result from interactions between brain and body, and are influenced by task goals and environmental factors.
