Carl Wernicke (1848-1905 was one of the
leading apshiasiologist of his day.
Aphasiologist – a
specialist who
deals with speech
disorders caused
by dysfunction of
the language
areas of the brain.
 In
1873, Carl Wernicke studied a patient
that had suffered a stroke. The patient
had trouble with speech. After
investigation, Wernicke discovered that
the patient had a lesion in the temporal
region. More specifically, the parietal,
temporal, and occipital lobes.
After seeing that the patient had damage
in the left temporal region. And also
struggle with speech. He hypothesized
that the region controlled speech
 Wernicke’s
area is located on the
temporal lobe of the left brain.
 It is responsible for:
1. Language comprehension
2. Semantic processing
3. Language Recognition
4. Language Interpretation

• P. Broca had described a frontal center and
added speech comprehension
• An impairment gave rise to sensory aphasia
opposed to motor aphasia
• Conduction aphasia, would result from an
interruption of the fibers.
