ideomotor
Pronunciation: eye-dee-oh-MOH-tor
Relating to the translation of ideas into motor actions, often used in apraxia contexts.
Full Definition
A neuropsychological concept describing the cognitive process of converting conceptual knowledge about actions into actual motor execution. In cognitive neurology, ideomotor function is frequently assessed when evaluating apraxia, where patients understand what action to perform but cannot execute it properly despite intact motor abilities. Ideomotor processing involves the left parietal cortex and connects gesture knowledge with motor programming. Disruption of ideomotor pathways results in characteristic errors where patients may use body parts as tools or produce spatially distorted movements when miming actions to command.
Usage
Usage note: Often used in conjunction with 'apraxia' - distinguish from ideational (conceptual) and limb-kinetic (motor) types.
In Context
