Temporal Lobe


Temporal Lobe, Temporal Lobe Function, Cerebral Temporal Lobe, Wernicke's Area, Brodmann Area 22, Auditory Area, Brodmann Area 41 and 42

  1. Wernicke's Area (Area 22)
    1. Dominant hemisphere lesions in Wernicke's Area result in receptive Aphasia (auditory Aphasia)
    2. The patient does not understand speech (including their own speech)
  2. Auditory Area (Area 41, 42)
    1. Hearing typically has bilateral input and therefore a lesion affecting one side only may result in no deficit
    2. Hearing Deficits are typically distal to the exit of the Cranial Nerve 8.
