How fish hear and make sounds at same time

The study marks the first time that scientists have found a direct line of communication between the part of a vertebrate’s brain that controls the vocal muscle system and the part of the ear that hears sound. The researchers believe that understanding the auditory system of the plainfin midshipman fish (Porichthys notatus ) — a 6- to 10-inch fish found along the coastline from Alaska to California — will offer insights into how other vertebrates — including humans — hear.
 

The general pattern of connections between neurons in the auditory system is the same in all vertebrates, including mammals. While humans hear with the cochlea of the inner ear, the midshipman uses the sacculus, a part of the ear that in humans detects acceleration or linear movement.

Because the study indicates a relationship between the ear and the auditory and vocalization systems of the brain, it could help scientists understand some of the mechanisms that contribute to deafness.
