Photopigment conversions expressed in receptor potential and membrane resistance of blowfly visual sense cells


IN spite of the fact that intracellular recordings from photoreceptor cells have been possible for many years and knowledge regarding the photochemistry of these cells has been steadily increasing, it is still unclear how resistance changes and potential changes of the cell membrane are mediated by photoconversion of the pigments located in that membrane. It is generally supposed that a link does exist between the photochemistry and the membrane phenomena, but evidence is sparse.
