What happens after neurotransmitter release ? Does electric signal pass less in light?
@InsightOphthalmology
@InsightOphthalmology 11 месяцев назад
Actually it quite counterintuitive and different things happen in on and off bipolar cells.In light, reduced glutamate release from photoreceptors causes the On bipolar cell to lose its inhibition and become active (depolarized) , i.e increase signal,, while the Off bipolar cell loses its excitation (becomes hyperpolarized) and becomes silent i.e decreased signal

We can discuss the on and off bipolar cells and further processing in another video if more people are interested :)
