Abstract:
The authors investigated the lesions and symptoms of five patients who presented with monoparesis of an upper limb due to cortical infarction. The location of the cortical motor hand area seems to be in the middle to lower portion of the anterior wall of the central sulcus. Severity of finger paralysis associated with impairment of this area varied in different fingers and occurred in two patterns: one variant predominantly affected the radial side, and the other predominantly affected the ulnar side.

Motor and Sensory Areas of the Cortex
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.

Association Areas of the Cortex
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
