The endocannabinoid system: a physiological perspective on its role in psychomotor control.
The discovery of cannabinoid receptors has led to the identification of two natural activators for these receptors, anandamide and 2-arachidonoylglycerol, and to the elucidation of their biochemical pathways of formation and inactivation. Although the physiological significance of the endogenous cannabinoid system is still poorly understood, important information is becoming available on the possible functional roles of this system in the basal ganglia, a forebrain region that is involved in the control of sensorimotor and motivational aspects of behavior. These discoveries - which are going to enrich the way in which we look at basal ganglia functions - are summarized in this mini-review. The role of the endocannabinoids as modulators of psychomotor behaviors and the potential therapeutic perspectives deriving from the pharmacological manipulation of the endogenous cannabinoid system are also discussed.
