Mental representations of movement patterns that enable the planning, execution, and learning of physical actions.

Motor Models

Motor models are internal representations in the brain that encode and predict the relationship between motor commands and their sensory consequences. These models serve as crucial building blocks for motor learning and skill acquisition.

Core Components

Forward Models

Forward models predict the sensory consequences of motor commands before they occur, allowing the brain to:

Anticipate movement outcomes
Detect errors between predicted and actual outcomes
Enable rapid motor control adjustments

Inverse Models

Inverse models compute the motor commands needed to achieve desired sensory states, functioning as:

Movement planners
Action selectors
Decision Making facilitators
