Rats were operantly conditioned for both increasing and decreasing the amplitude of one component of both visual and somatic sensory evoked potentials. The potentials were recorded in visual cortex, somatic sensory cortex, or nucleus intercollicularis in the midbrain reticular formation. The visual cortical potentials were evoked by shocks to the optic chiasm. The somatic sensory cortical and subcortical potentials were evoked by shocks to the nucleus subcoeruleus of the pontine reticular formation. The evoking stimuli (shocks) were presented at random intervals. The results rule out trivial mediation of operant neural control and are discussed in these terms.
