Visual Processing and the Visual Cortex

We learned about the structure of the eye in the Anatomy and Physiology series. But how do we process visual information? Light hits the retina at the back of the eye, and then what happens? Well quite a lot, to be honest! We have to go deeper regarding retinal structure, neural pathways to the brain, and the regions of the brain that receive and process this information, which are collectively referred to as the visual cortex. So let's get a closer look!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Bruh, I read the section in my textbook on this about 15 times, and it just didnt click. You sir, are a gentleman and scholar.

Honestly speaking, this is the best video for vision explanation I have seen so far. Detailed, short, talking slowly and writing the key points. Perfect for teaching . Thanks professor Dave.

[10:17] Just a tweak: glutamate is an excitatory neurotransmitter, and this is not an exception in the eye. The way it inhibits signal transduction, rather, is by stimulating the release of GABA in horizontal cells, which is an inhibitory neurotransmitter.

I remember when I was taking Gen Chem 4 years ago, your videos helped me understand things so well. Now that I'm taking upper neuroscience courses, you're STILL pulling through. You're a God sent!!

In university it took 40 hours to complete all this. and you just made it possible to understand in 16 minutes. just wow. amazing!!

[RockerProf]

Fantastic video. Your visual graphics very well done and helpful.Thank you for making this. It helps me understand much better how musicians process sight reading musical notes.

[mitsunori]

Just what I've been waiting for. Thanks.

Great job Professor, a really complete session about vision and all its path!! Congrats!

[emat]

This was very informative and helpful, thank you!

[jean-antoinenorbert]

Really great content and presentation!

[hypothesised]

thank you for this v concise explanation of the three weeks of class content i missed while i was ill! :, )

Hello Professor Dave. I am admiring the work that you do, I want to suggest a topic for a future video. Can you please explain, how does fermentation and mould work. Thank you

[marianbundel]

Simply amazing. Thank you very much Dave!!!!

[roksanadawil]

Thank you so much, that helped me a lot :) I learnt more about how does the visual system in our minds work :)

[LiftersClinic]

Excellent review of the intersections topics that unite cell biology to organism.

Hi Professor Dave, Can you help please. I want to change the wavelength of the Bragg mirror according to random distribution But i don't have any idia about the mathimaticals formula used to discribed this variation.
