Abstract:
In this paper we present a new method for studying auditory
systems based on m-sequences. The method allows us to
perturbatively study the linear response of the system in the
presence of various other stimuli, such as speech or sinusoidal
modulations. This allows one to construct linear kernels (receptive
fields) at the same time that other stimuli are being presented.
Using the method we calculate the modulation transfer function of
single units in the inferior colliculus of the cat at different
operating points and discuss nonlinearities in the response.
