The effects of exposure to 48 h darkness and to stroboscope stimulation on chick optic lobe adenylate-cyclase activity were studied. A significant decrease in adenylate-cyclase after 48 h exposure to darkness occurred with return to normal values after re-exposure to light. Stroboscope stimulation for 3 min produced instead a marked increase in optic lobe adenylate-cyclase. Present experiments suggest that cAMP may serve as inhibitory messenger in synaptic transmission along central visual pathways.

Abstract
The effects of exposure to 48 h darkness and to stroboscope stimulation on chick optic lobe adenylate-cyclase activity were studied. A significant decrease in adenylate-cyclase after 48 h exposure to darkness occurred with return to normal values after re-exposure to light. Stroboscope stimulation for 3 min produced instead a marked increase in optic lobe adenylate-cyclase. Present experiments suggest that cAMP may serve as inhibitory messenger in synaptic transmission along central visual pathways.File in questo prodotto:
