description

To study the influence of vitamin A on hearing we choose to examine ECoGs induced by an audible stimulus.The basis of this project is a suitable experimental equipment for inducing and recording inner ear electrical responses in guinea pigs. The problem to be studied asks for a high number of animals and measurements within one animal; furthermore the ECoGs of each animal have to be examined over a long period of time. This calls for a simple and automated measurement and evaluation procedure. In contrats to most ECoG experiments we do not study the influence of special oto — toxic agents (noise,drugs etc) but examine the variation of ECoG signals as caused by different metabolic states of vitamin A.Consequntly only slight variations in the electrophysiological signals are expected.This demands for an exact and hicihly reliable measurement apparatus.To fullfill these requirements we choose to design a highly computorised equipment.
