Small cortical strokes may cause predominant weakness restricted to a particular group of fingers. However, clinical, radiologic, and etiopathogenetical studies have rarely been done in these patients. The results agree with traditionally alleged topography for fingers in the human motor cortex: ulnar fingers-medial and radial fingers-lateral. However, whether this result indicates a point-to-point somatotopical representation or differential threshold of excitability in individual neuron s remains unknown. Sensory topography seems to be closely associated with that of motor function in individual subjects. The motor cortex representing ulnar-sided fingers may be a borderzone area between large arteries. |
