Scientists shed light on the brain mechanisms behind a debilitating sleep disorder

«Cataplexy is characterized by muscle paralysis during cognitive awareness, but we didn’t understand how this happened until now, said John Peever of the University of Toronto’s Department of Cell & Systems Biology. «We have shown that the neuro-degeneration of the brain cells that synthesize the chemical hypocretin causes the noradrenaline system to malfunction. When the norandrenaline system stops working properly, it fails to keep the motor and cognitive systems coupled. This results in cat…
