- In this video, Dr. Kushner examines the parts of the eye (iris, cornea, lens, retina) and how information flows from the eye to the brain for processing.

Check your understanding: What is the blind spot?
A. a region in the back of the retina where the bipolar cells and retinal ganglion cells meet
B. a small area at the back of the retina where there are no photoreceptor cells
C. an x-shaped structure where the two optic nerves meet in front of the thalamus
D. a region in the visual cortex that contains no rods or cones
E. a small area in the middle of the retina that contains the highest concentration of cones

This is the best vision video I've seen, thank you so much!!
You're so welcome!😉
You are GREAT teacher. Keeping making videos like this. ❤Thank you so so much for sharing your knowledge.
Thank you, I will
Yes, you are! The most clear videos I have ever watched!!!😮
Oh my goodness! Thank you so much for posting this. I was so confused about the visual pathway until I watched this. Keep doing what you're doing :D!!
wow best video i’ve seen explained everything so simply i actually understood it
These videos are so well made - I can't believe it. Your vids are so helpful for studying for the MCAT, thanks!
Happy to hear that!
you made things so much clearer for me. no pun intended. thank you!!
Eye see what you did there 🤓
Thank you so much for this detailed explanation. God bless🤲
great videos
You explain things so well, so glad I found your videos
Glad you like them!
Excellent explanation...please keep posting more videos on Psychology. Too good
Thanks a lot ! You are making a difference!
Absolutely amazing
🙏 Thanks Sir for such a great video.
I could cry, Why? Because I am so happy I found your videos. Kind regards from Iceland
Such kind words! Thank you from Illinois, USA. Are you a teacher or student, or just interested in learning about the mind?
Great Explanation
Thank you 😊
wowwwwwww thankyouuu so much best explination
Happy to help
Could you do another video focusing on receptive fields in detail
My next video is going to be on the synapse!
🙏
To my mind (pun intended), this is a very good description of how a certain bandwidth of frequencies out there in the cosmic -- dare I say, holographic -- soup are processed by eye and brain parts attuned to react to specific measurements like color type, light amount, and so forth. And so the whole thing hums along inside the dark cave of my head as described. However, this feels like the map and not the actual road. Where's the image? Why, when I dream, when my sensory input valves (i.e., my eyeballs) and its corresponding processing is shut off, do I "see" images in my dream consciousness?
