Answer 2

Once the cilia in cochlea of our ear receives auditory stimuli then convert them into electrical impulses and sent to auditory center (auditory cortex) in temporal lobe of the brain through auditory nerve.

Processing of Sound signals

• processing of sound signals is done in three stages, it is also called as Primary auditory path.

1. Stage - I : Signal is processed at brain stem and decodes the information like duration and frequency of sound, and the message is passed to two additional relays (small group of neurons) for localisation of sound.
2. Stage - II : Signal is processed by Thalamus which is located at the base of cerebrum, it integrates sensory system in the body, so that it may lead to motor response.
3. Stage - III : From thalamus it is connected to auditory cortex as most of the message is decoded, here it recognize, memorizes and the leading to response.
