Dorsal column input to cochlear neurons in decerebrate-decerebellate cats.
In decerebrate-decerebellate cats with cervical spinal cuts sparing only the dorsal columns (DCs), activation of one DC modulates sound-evoked discharges of neurons in both dorsal cochlear nuclei. In a sample of 50 neurons, 34% were excited or facilitated, 12% were inhibited and 54% were not affected by DC stimulation. This modulation appears to be mediated through direct projections from the dorsal column nuclei to the dorsal cochlear nuclei.
