Wernicke-Geschwind Modell

Paul Broca

  • First to discover different functions are assigned to different parts of the brain
  • localization of speech function in the left inferior frontal

gyrus

  • Dicovered 'Broca's Area'
  • Saved hundreds of human brains in jars of formalin

"The least questioned assumptions are

often the most questionable."

A Brief History

  • The Wernicke-Geschwind Modell gives an explanation of the production and comprehesion of language, and an explanation for language difficulties.
  • Wernicke started this research, but Geschwind expanded and refined this research.
  • Broca must also be mentioned for his research which intertwines with the modell

Norman Geschwind

  • Pioneering Behavioral Neurologist
  • Best known for models based on lesion analysis
  • Expanded on studies done by Carl Wernicke
  • Geschwind Syndrome: describes an interictal behavior pattern seen in some temporal lobe epileptics

Wernicke-Geschwind Model

Carl Wernicke

  • Found patients with lesions in posterior third of the temporal gyrus lost ability to understand words
  • Discovered 'Wernicke's Area'
  • Named Aphasia: language deficits resulting from brain-related injuries
  • Died from injuries suffered by a bicycling accident
