These areas correspond to Broca's area, Wernicke's area
, and the posterior language association area (Pinel, 2000).
If the Wernicke's area
of the brain is damaged, people have difficulty understanding spoken and written language.
While targeted testing is preferable, often both Broca's and Wernicke's areas
are activated during both productive and receptive language tasks, making it not essential to tailor the language task to the lesion location.
Unfortunately for phrenology, experimental science proved, even as early as the 1870's with the discovery of Wernicke's area
, that its claims were unfounded.
Over time, while Wernicke's area
remained damaged, an adjacent area took on this cognitive task.
is located adjacent to the area associated with the reception of auditory stimuli Heschle's gyrus, and Broca's area is located close to the cortical areas assigned to the motor control of the muscles of articulation.
Conspicuously absent, however, was activation in either Broca's or Wernicke's areas
, even though activation of Wernicke's area
would be predictable from any processing model holding that visually presented words are necessarily recoded through their phonological representations before being reproduced aloud (p.
According to Julian Jaynes, the phenomenon of inspiration as the hearing of voices (of the Muses or of any other agency) is explained by the fact that the right hemisphere (parieto/temporal location corresponding to Wernicke's area
) originates auditory signals which are transmitted to the left hemisphere's Wernicke's area
through the anterior commissure.
is the part responsible for understanding speech.
The primary auditory area, also known as Wernicke's area
, is located in the superior temporal gyrus.
is quite close to the auditory cortex, the brain region that controls the input and analysis of sound.
