The premotor cortex lies on the lateral frontal lobe just in front of the primary motor cortex, mainly in Brodmann area 6. It plans movements and links them to sensory cues, especially vision. It contains mirror neurons that fire both when performing and observing an action.

Selects and plans movements based on sensory cues, especially for reaching and grasping, and prepares the motor cortex to act.
Damage tends to cause clumsiness and difficulty sequencing or choosing movements, rather than true weakness, sometimes with apraxia. Premotor lesions may also cause increased tone. It contributes to recovery after motor cortex stroke, taking over some functions of damaged areas.
Loss of fine, skilled movements of a limb despite normal strength after premotor damage.
Difficulty with movement sequences and visually guided movements after lateral premotor lesions.
