A variety of diseases affect these neurons, and specific diseases affect either the upper motor neuron or the lower motor neuron differentially. Amyotrophic lateral sclerosis (ALS, Lou Gehrig’s disease) is the best know of the motor […]

Most aphasias are the result of infarction of branches of the Middle Cerebral Artery, either affecting Broca’s area (Brodmann’s areas 44 and 45) or Wernicke’s area (Brodmann’s area 22). However aphasia […]
