How does the brain process sound

If there is a large bang your auditory system will direct your attention to that sounds because of the novelty and relative differenc.This is a form of brain imaging that allows us to see which regions of the brain are involved in a particular task:Sound moves through the middle ear.The middle ear passes these vibrations to the inner ear.;According to peoppel, the brain waves surf on the sound waves..

These nerve endings transform the vibrations into electrical impulses that then travel.It achieves this, in part, by distinguishing speech from other kinds of sound in about a tenth of a second after the sound enters the ears.We usually think that what the brain processes this early must be only at the level of sound, without regard for.The colored sections show where the brain is working, with brighter areas indicating more activity.Here's a scan that shows the brain responding to sounds from a ci:

Some took it that this meant the two sides of the brain played different roles in the perception of sounds and, in their view, the left hemisphere was more strongly associated with the processing.The tiny hair cells in our inner ear send electrical signals to the auditory nerve which is connected to the auditory centre of the brain where the electrical impulses are perceived by the.This is then cut into chunks, known as an entrained signal.Hearing depends on a series of complex steps that change sound waves in the air into electrical signals.The first place they go is the auditory cortex, where the envelope or frequency is translated.

These results represent a significant advance in understanding how sound is encoded for transmission to the brain, according to the authors, whose work is published with an accompanying news and views editorial in the feb.
