@CryInTheAttic ON bipolar cells are activated by the light and cause hyperpolarization in response to glutamate and OFF bipolar cells are inactivated by light and cause depolarization(opening of sodium channels) . They are named based on their responses to glutamate that is released by the photoreceptors.
The one he talked about in the video is the response to light, hope this helps!
@afrprincess07 There is an AP being sent to the brain, in the dark the rods are the only ones active, hence you can only contrast and see in black and white. The rods depolarize and develop and action potential and they release neurotransmitters, which hyperpolarize bipolar cells and sense these bipolar cells cant produce an AP they dont produce their AP inhibiting neurotransmitters which are meant for the ganglion cells, so the uninhibited ganglion cells fire an AP
These videos are so good and you explain everything incredibly well. creds to you!
Alot of your videos are good for a part of my class this semester, an idea though, could you possibly make on about the color processing from cones to the brain?
@ceenja Hi! Thank you for taking time to watch our videos. We're glad that you're finding value in them. Unfortunately, Leslie is no longer taking requests for specific videos, but he will definitely get to more Biology topics in the future. He has many to work on at the moment. So stay tuned for more!
You videos are phenomenal!! I'm in the introductory neuroscience class at MIT, and your tutorial makes what we went over in lecture much more clear. Thanks SO much!:)
u said that the action in cones are similar to rods but cones can activate only in the presence of light unlike rods.....so how s the cones getting stimilated????
@monicathukkaramnt The way I understood is that rods are more sensitive to light, so when it is dark they still fire, which helps with night vision, hence rods produce black and white vision, but when there is a good amount of light, lets say, like in the daytime, the cones become activated because they require a lot of light to be stimulated. Also remember the part he says, during presence of light, the lens is more focus on the fovea region of the eye, which has the most concentration of cones
Respond to this video... Rods and cones both get activated by light, because they both have pigments (but different pigments) and pigments absorb light, and the pigments in the rods are more sensitive to light, so keep firing even at night, but cone pigments are less sensitive so cone pigments require higher amount of light to become activated.
@naru24dude hi, i have a question for you because you seem to understand this very well. if there is no action potential being sent to the brain when the rods are active in the dark, then how in the world are the rods working? i think im missing a step. please help if you can!

I like your accent. I like the pretty pictures. I can see clearly now the rain is gone, it's gonna be a bright, bright sunshiney day.....................don't mind me. It's the exams.
Please excuse my vulgar name for my account but I had to say this. I have been using the information from these videos focusing on the eye and such and have been using them as sources for data in my science research course. I ahve to say, these videos make my life 100% easier in collecting information for my topic. I salute you.
How does the decrease of NT in rods increase the NT in bipolar cells? I know that NT from the rod are inhibiting the release of NT in bipolar, but what is giving the bipolar cells their initial action potential?
Also, you said that there is no action potential in the bipolar cell, so how does that work?
@pirateXhunterXzoro Great questions. The bipolar cells are usually inhibited by the neurotransmitters released by the rods. So normally, they don't release many neurotransmitters (if any at all). It's as if the rods are holding them back. Once the rods stop, they depolarize and are free to release their neurotransmitters. It's not an action potential.
The only way to have an action potential is by having an axon with v-gated channels. However, any cell can be depolarized. Hope that helps!
@Cesare107 I hear you. I remember the same thing happening with me. I didn't get it and kept probing. When I found out that the Neurotransmitters were inhibitory, it was as if the light bulb finally went on in my brain :)
These videos are very helpful in understanding the material, keep them coming! :)

hyperpolarisation might make sense if you include the passive and continuous outflux of K+ ...no Na in then the cell becomes more negative.

@monicathukkaramnt The higher amount of light present, the more cones active, producing finer/detailed images with color in the brain.
