Hearing defect in menier's disease:
Ans. (c) DiplacusisRefi PL Dhingra ,5thed.pg no: 112WHY DIPLACUSIS?* In the abnormal ear, neurons respond to a broader range of stimulus frequencies. But due to CNS preconditioning, the brain interprets any activity in a particular neuron as resulting from a stimulus of its normal characteristic frequency. Thus a single stimulus simultaneously processed by the normal and abnormal cochlea willbe perceived as two different stimuli by the CNS, thus leading to diplacusis.
