- •
Distortion products (DPs) can be produced by cochlear nonlinearities.
- •
DPs are also produced by the Sensimetrics earphones commonly used in fMRI studies.
- •
Earphone DPs can be high in amplitude, and can alter cortical pitch responses.
- •
Cochlear DPs had lower amplitudes, and a smaller effect on cortical responses.
- •
Stimuli are introduced that localize pitch-responsive areas while minimizing DPs.
