The primary auditory cortex (A1) is located on the superior temporal gyrus in the temporal lobe and receives point-to-point input from the ventral division of the medial geniculate complex; thus, it contains a precise tonotopic map.
The primary auditory cortex is located in thetemporal lobe. There are additional areas of the human cerebral cortex that are involved in processing sound, in the frontal and parietal lobes.

Is the primary auditory cortex on both sides?
It is located bilaterally, roughly at the upper sides of the temporal lobes – in humans, curving down and onto the medial surface, on the superior temporal plane, within the lateral sulcus and comprising parts of the transverse temporal gyri, and the superior temporal gyrus, including the planum polare and planum
What is the function of the primary auditory cortex?
The auditory cortex plays a critical role in our ability to perceive sound. It is thought to be integral to our perception of the fundamental aspects of an auditory stimulus, like the pitch of the sound.
In which lobe of the brain is the primary visual cortex located?
The occipital lobe is the major visual processing centre in the brain. The primary visual cortex, also known as V1, receives visual information from the eyes. This information is relayed to several secondary visual processing areas, which interpret depth, distance, location and the identity of seen objects.
Where is the auditory cortex located and how are its cells organized?
The primary auditory cortex is organized in vertical columns with the cells in each column sensitive to the same main sound frequency. Adjacent columns are organized according to the tonotopic representation (from lower frequency to higher frequency moving from posterior to anterior).
What part of your brain is responsible for hearing?
The auditory cortex is found in the temporal lobe. Most of it is hidden from view, buried deep within a fissure called the lateral sulcus. Some auditory cortex is visible on the external surface the brain, however, as it extends to a gyrus called the superior temporal gyrus.
What part of the brain controls the ears?
Temporal Lobe: side of head above ears situated immediately behind and below the frontal lobes; the temporal lobe controls memory, speech and comprehension.
What is the primary motor cortex?
The primary motor cortex, located just in front of the central sulcus, is the area that provides the most important signal for the production of skilled movements. Electrical stimulation of this area results in focal movements of muscle groups on the opposite side of the body, depending on the area stimulated.
What would happen if the primary visual cortex is damaged?
Destruction of the primary visual cortex leads to blindness in the part of the visual field that corresponds to the damaged cortical representation. The area of blindness – known as a scotoma – is in the visual field opposite the damaged hemisphere and can vary from a small area up to the entire hemifield.
Is it true that the primary visual cortex is located in the parietal lobe?
The primary visual cortex is found in the occipital lobe in both cerebral hemispheres. It surrounds and extends into a deep sulcus called the calcarine sulcus.
What part of the brain is most active in decision making?
The Prefrontal Cortex (PFC) and hippocampus are the most critical parts of the human brain for decision making.
What is special about the location of the primary somatosensory cortex?
This cortex is located within the which is located in the postcentral gyrus of the parietal lobe, and lies behind the primary motor cortex of the frontal lobe. The somatosensory cortex receives tactile information from the body, including sensations such as touch, pressure, temperature, and pain.
