What is the primary auditory bark?

The primary auditory bark is one of the three parts that make up the auditory bark. It is located between secondary and tertiary auditory cortex in the time lobe of the brain. This part of the bark is responsible for processing sound information for the brain.

All sensory information must be processed by the cortical area of ​​the brain to be perceived. Sound information is processed by the primary auditory bark. Details of sound, such as frequency, location and volume, are processed in this particular part of the auditory bark. It has the ability to respond to different frequencies.

The primary bark is divided by neurons. Each of these neurons is grouped according to specific sound frequencies to which they respond. Neuronal sound coding is a process that distinguishes neurons. Within the primary auditory bark, each area responds to different frequencies. For example, the front area is more responded to higher frequencies, while the rear area reacts better to lower frequencies.

Damage to primary auditory bark can cause many problems. When the whole primary area is damaged, one is not aware of the sounds that are heard, but this person still has the ability to act in reflection on any sounds. For example, with this problem, one could fall to a loud noise, but could not tell anyone what noise was heard or why the frightened reaction occurred. This damage prevents the primary area of ​​processing sound information into perception.

partial damage to the primary auditory bark is not nearly as serious as the whole damage, but also causes some hearing problems. If only one part of the primary area is damaged, certain frequencies are not perceived. For example, if one part that processes low -frequency sound is damaged, the brain does not perceive any sounds would be processed by this section. Medium levels and high frequencies are not affected. Similar to the whole damage, the sound is heard, but it is not entirely wellCava.

There are several effects of noise health that can lead to damage to primary auditory cortex. Congenital defects cause damage found in newborns. Some diseases such as meningitis and chickenpox can lead to hearing bark damage and hearing loss. Most often, however, the permanent exhibition leads to damage to loud noise. In some cases, the damage is temporary, but in many cases the damage may be permanent.
