SNAB topic 8: light reception by rod cells

quick explanation of the event of light reception by rod cells and the generation of impulses in the optic nerve cells.

This explanation just couldn't get any better, its literally perfect. this is exactly what i wanted when i requested you to make a video on rodopsins and action potential. you are helping countless students like me with these videos and i can't thank you enough for everything you do for us. Thanks again Dr.

Thanks so much for the video:) I have a question why here 9:14 you said that the bipolar will be depolarized and before that it is hyperpolarized where does all the positive ions that cause it to depolarize come from?

[@LSCBiology]

these ions are dissolved in the tissue fluid (outside the cell). there's more of them outside because cells are actively transporting them out of the cell's cytoplasm.

[@hanamostafa5268]

@@LSCBiology so there are chloride ions in the cell's cytoplasm after the hyperpolarization and they are then being actively transported out of the cell causing the cell to be depolarized ?
