Rod cell"s signal transduction pathway: when light is detected, an ion channel closes and the membrane hyperpolarizes, when in the dark, it releases the neurotransmitter, when in the light, no neurotransmitters are released. Light and the synapse: boundaries between one object from another, the ganglia find the edges between the objects.
