Study: Cannabinoids Enhances Visual Responses

Vision1A new study being published in the next issue of the journal eLife, and published online ahead of print by the U.S. National Institute of Health, has found that cannabinoids can enhance visual responses.

“Type 1 cannabinoid receptors (CB1Rs) are widely expressed in the vertebrate retina but the role of endocannabinoids in vision is not fully understood”, the study’s abstract begins. “Here we identified a novel mechanism underlying a CB1R-mediated increase in retinal ganglion cell (RGC) intrinsic excitability acting through AMPK-dependent inhibition of NKCC1 activity.”
