Abstract
We have investigated the effect of the laterodorsal tegmental (LDTg) stimulation on evoked potentials in the intergeniculate leaflet (IGL) of the rat, in order to characterize how non-specific systems of the brain, whose activity indicates the influence of non-photic information, impact the activity of the IGL. IGL responses were evoked by electrical stimulation of contralateral suprachiasmatic nuclei (SCN). The amplitude of the evoked potentials was, in all experiments, significantly reduced after the LDTg stimulation. This effect indicated strong neuronal integration between the brainstem reticular formation and the IGL. These results are discussed in relation to the putative role of GABAergic projection.
