What part of the brain is the busiest?
Different activities activate different areas of the brain. Sight and sound are located in different areas. I do better reading than listening. just ask my wife.
How does the message from the ear get to the brain?
The sound waves in air entering the ear strike the ear drum (the 'tympanum') and cause it to vibrate. Those mechanical vibrations transfer through a chain of three tiny bones (the 'hammer', 'anvil', and 'stirrup') behind the ear drum, and the vibrations finally transfer to the 'cochlea' ... a closed tube, wound in a spiral, full of liquid, and lined with tiny hairs on the inside of its walls. The liquid in the cochlea picks up the vibrations, and they run up and down the inside of the tube until they die out. During that time, they run past the tiny hairs, and each of those is the end of a nerve. So when the tiny hair vibrates, a tiny signal is generated in the nerve, and that's the signal that finally flows to the brain.
The brain's willingness to recognize and to respond to a sound is called?
attention.
How are sound localization and time related?
When a sound reaches one ear, the additional time it takes for the sound to reach the other ear helps the brain estimate the origin of the sound.
What do scientists call the limbic system in the brain?
because is sound good
Where is the cochlea located?
Yes. It is a snail-shell shaped organ with tiny hairs lining the inside that move to sound waves, sending impulses to the brain, which the brain translates as sound.
How does your brain use tiny hairs to interpret signals as sound?
The cochlea has tiny hairs. These are held by the Organ of Corti. The tectorial membrane moves over the hair when sound waves move it. The hairs are stimulated. This structure is really the organ for hearing.
What happens to an ear when sound waves travel through it?
Sound travels into the ear where it goes into the ear drum which looks similar to a snail shell which has many many tiny hairs attached to it. When the sound waves hit the hairs, the hairs begin to vibrate according to the frequency of the sound waves. Certain hairs register certain frequencies and sends signals to the brain which registers those vibrations as sound.
In which part of the ear are the cells that are senstive to sound?
The hairs in the cochlea are responsible for producing the nerve impulses that travel to the brain's temporal lobes to be interpreted as sound.
Does sound go through your ears?
Yes, sound is recognized by the brain through your ears. When you hear a sound, it enters the ear canal to the eardrum. The eardrum causes small bones to vibrate, which causes tiny hairs to send signals to the brain.
Where in the human body can you find the cochlea?
The cochlea is located at the end of the ear canal - inside the ear. It contains fluid and microscopic hairs (cilia). Sound waves received by the ear causes movement of the cilia - which is interpreted by the brain.
What is the actual site of hearing?
The eardrum vibrates the sound. The sound is carried to the cochlea where little "hairs" bend and the sound is then carried to the auditory nerve to the brain. There are other bones and things that are part of the hearing mechanism but I have described how the ear takes in sound and sends it to the brain in the simplest terms possible.
What is the part of the ear that responds to sound waves lika a microphones diaphragm?
The whole ear gathers sound. Deep inside there are bone tubes (called Inner Ear) with liquid and hair looking things inside (Hair cells). Sound makes the water and hairs move. The hairs send a signal to the brain. The brain puts it together so we can understand sounds and music.
Sound is a from of?
Waves and vibrations in the air, Picked up by little hairs in your ears that vibrate and reproduce the sound into a form your brain can interpret. (very short and bare bones answer but that is jist of it)
How does the cochlea detect sound signals?
the cells of the hairs don't detect the sound waves at all. The full hair is vibrated by the sound waves and this vibration is picked up by nerves and the info is sent to the brain.
What is the role of hair cells in the cochela?
The Cochlea is a part of the ear that turns the vibrations in the small bones into electrical information. The electrical information is channeled through the nerves, into the brain. The Cochlea is a part of the ear that turns the vibrations in the small bones into electrical information. The electrical information is channeled through the nerves, into the brain.
What metals conduct sound?
All metals can conduct sound, but some conduct it a bit better than others.
