Abstract
The functional relation between the olfactory bulb and the subcortical activating system was investigated in the curarized rabbits. The intrinsic and the induced waves of the olfactory bulb were suppressed by high frequency stimulation of the mesencephalic reticular formation and the posterior hypothalamus. In contrast to this, anterior hypothalamic stimulation mostly resulted in augmentation of both kinds of electrical activity, but in some cases only the intrinsic waves were enhanced with the induced ones suppressed. These findings were discussed in comparison with those of the previous investigators.
