Is Wernicke's area in the temporal or parietal lobe?
Structure. Wernicke's area is traditionally viewed as being located in the posterior section of the superior temporal gyrus (STG), usually in the left cerebral hemisphere. This area encircles the auditory cortex on the lateral sulcus, the part of the brain where the temporal lobe and parietal lobe meet.
Is Wernicke's area in cerebral cortex?
Typically, however, Wernicke's area is considered to reside in the cortex of the left cerebral hemisphere, surrounding a large groove called the lateral sulcus or Sylvian fissure, near the junction between the parietal and temporal lobes.
What lobe are the Broca's and Wernicke's areas located in?
Broca's and Wernicke's areas are cortical areas specialized for production and comprehension, respectively, of human language. Broca's area is found in the left inferior frontal gyrus and Wernicke's area is located in the left posterior superior temporal gyrus.
The frontal lobes are located directly behind the forehead. The frontal lobes are the largest lobes in the human brain and they are also the most common region of injury in traumatic brain injury. The frontal lobes are considered our behaviour and emotional control centre and home to our personality.
Wernicke area receives its vascular supply from the inferior temporal branch of the middle cerebral artery. The temporal lobe drains blood via 2 primary routes.
The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
The bulk of the lateral surface of the hemisphere; except for the superior inch of the frontal and parietal lobe (anterior cerebral artery), and the inferior part of the temporal lobe. Superior division supplies lateroinferior frontal lobe (location of Broca's area i.e. language expression)
The Wernicke area is located in the posterior third of the upper temporal convolution of the left hemisphere of the brain. Thus, it lies close to the auditory cortex.
Damage to the temporal lobe of the brain may result in Wernicke's aphasia (see figure), the most common type of fluent aphasia. People with Wernicke's aphasia may speak in long, complete sentences that have no meaning, adding unnecessary words and even creating made-up words.
The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental mammals.

Paul Broca was one of the earlier advocators for the idea of lateralization of brain function. Broca's area is strong evidence that language functions of the brain are lateralized to specific brain regions.
The temporal lobes sit behind the ears and are the second largest lobe. They are most commonly associated with processing auditory information and with the encoding of memory.
When Tan died, Broca studied his brain and found a lesion (a bruise or yucky spot) on the front of the temporal lobe. Broca then went and studied other brains of patients who were similar to Tan. This is how he discovered Broca's area.
The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain's primary somatic sensory cortex (see image 2), a region where the brain interprets input from other areas of the body.
The cerebrum is the largest part of the brain. It is responsible for memory, speech, the senses, and emotional response. It is divided into four sections called lobes: the frontal, temporal, parietal, and occipital. Each handles a specific segment of the cerebrum's jobs.
