In vivo oxymetric analysis of mild hypercapnia upon cerebral oxygen, temperature and blood flow: markers of mood as proposed by concomitant bupropion challenge and electrochemical analysis?

abstract：:Vibratory stimulation of the neck muscles can elicit illusory drift of a visual target; after vibration stops, motion in the opposite direction is perceived. This motion aftereffect (MAE) could be due to adaptation of proprioceptive mechanisms that encode head orientation, or at a stage where visual and proprioceptive...
