Behaviour-dependent variability of potentials in the somatosensory cortex evoked by stimulation of the trigeminal nuclei in freely moving rats.

Abstract

Nine hooded rats with chronically implanted epidural recording electrodes on the right primary somatosensory cortex, the olfactory bulb and bipolar stimulating electrodes in the left ponto-mesencephalic trigeminal nuclei and parabrachial region were investigated during different patterns of spontaneous behaviour. The early positive-negative component of the… (More)
