P26-S Left and right motor cortical excitability and relationship to motor functions in healthy adolescents

The interhemispheric difference in cortical excitability and its relationship to motor functions is unclear. We examined the relationship between handedness, left and right motor cortex excitability and fine and gross motor functions in adolescence. 28 healthy adolescents (age 16–19 years, 19 girls) were studied. Handedness was determined by the Waterloo Handedness Questionnaire. Motor threshold (MT) of the abductor pollicis brevis was measured...
