Marconis Posted November 18, 2010 Share Posted November 18, 2010 (edited) Why is the default potential of a photoreceptor cell hyperpolarized? Why is it that more neurotransmitter is released in the dark than in response to light? I can't understand this and my textbook does not go into why it is the case, it just states it as a matter of fact and being "unique". Thanks!
