characteristics of chemically induced noise in Musca photoreceptors

Photoreceptors of Musca were superfused with solutions containing either fluoride (F super(-)), vanadate (VO sub(3)u-), or one of the GTP analogs GPPNHP and GTP gamma S. All four agents produced noisy depolarizations in Musca) photoreceptors when added to the perfusate. F super(-), VO sub(3)u- GPPNH...

Description
Summary:	Photoreceptors of Musca were superfused with solutions containing either fluoride (F super(-)), vanadate (VO sub(3)u-), or one of the GTP analogs GPPNHP and GTP gamma S. All four agents produced noisy depolarizations in Musca) photoreceptors when added to the perfusate. F super(-), VO sub(3)u- GPPNHP and GTP gamma S appear to generate noise in Musca) photoreceptors through a common effect on the pathway of phototransduction. In the case of F super(-) in particular, chemically induced bumps are smaller and less affected by adaptation than those produced by light.
