Electrocochleography

 

                                                                        Auditory Pathway

 

Electrocochleography (ECoG) is a diagnostic technique used to record electrical potentials generated in the inner ear (cochlea) and auditory nerve in response to sound stimulation. It has played an important role in understanding cochlear physiology 

 

 

The origins of ECoG trace back to the pioneering work of Hallowell Davis and Saul B. G. T. Derbyshire in the 1930s.

• In 1935, they recorded the cochlear microphonic (CM) from animal models.

• Their work demonstrated that the cochlea produces electrical potentials that mirror acoustic stimuli.

• These discoveries confirmed that hearing involves measurable bioelectrical activity.
