Highlights
Our results indicate that OCB stimulation can modify cochlear nucleus units in a variety of ways
The acoustic signals used were relevant for evaluating the effects of OCB stimulation on intensity functions, and other parameters such as the shape of the tuning curve, the response to noise, etc., were not examined. These experiments examined the effects of stimulating the OCB at its point of decussation in the floor of the IVth ventricle on both spontaneous and tone-evoked activities in 121 single units in cochlear nucleus of unanesthetized, decerebrate cats
Spontaneous discharge rates were unaffected in 51% of the units, decreased in 31y& and increased in 18%
Summary
The purpose of the present study was to investigate the effects of OCB stimulation on spontaneous and tone-evoked activities of single units in cochlear nucleus, the first central auditory station receiving cochlear input
