Infraslow brain potentials of neuromodulatory centers and highest cortical sensory areas

We identified and studied the dynamical properties of the infraslow brain poten- tials of different neuromodulatory centers of the rats - locus coeruleus, nucleus raphe dorsalis and nucleus basalis magnocellularis. Moderate linear correlation (0.45≤r≤0.65) of multisecond waves between neuromodulatory centers and cortical sensory areas indicates the possible involvement of this infraslow domain in modulatory influences of locus coeruleus, dorsal raphe nucleus and nucleus basalis magnocellularis on sensory information neuroprocessing in the primary visual auditory and gustatory cortices.
