034 How Lateral Inhibition enhances Visual Edges

http://www.interactive-biology.com - In this video, I talk about the process of lateral inhibition, and how it enhances visual edges. I do that by putting two rectangles next to each other. Watch this video to see what happens.

Is it bad if I don't see the lighter edge when you combine the two shades of gray? I am using a 1080p, 120hz, 22inch computer monitor and full screen 720p hd video stream. I don't see it. I have looked at other pictures and videos that demonstrate this concept and I still don't see but my friend does. What does this mean about my eyes? Am I going color blind?

@pfshepherd2010 Unfortunately, Leslie has a lot of work to do right now to be able to attend to the number of emails he's been receiving lately. I would strongly suggest though that you go and see an eye doctor about your observations just to be sure. We hope it's nothing that complicated... Do take care!

lighter becomes lighter. darker becomes darker. darker side gets more inhibted as it is less stimulated than the lighter side.

But why the edge on darker side looks even darker? more inhibition reached to the edge than the far end?

Lighter side looks lighter in the edge why? are there inhibition to the non-edge side of the lighter side? why?

Is there selective inhibition to cons and rods?

im so confused :s

@zusamin1 All questions are answered in the Interactive Biology community forums from now on. Go to the website in the description and then visit the community. This is to make it as efficient as possible as we have multiple people over there to help answer questions.

You are excellent. This helped me out so much for my Physiological Psychology exam. Thanks!

@Bpatel8519 Great to hear. Thanks for the feedback. Stay tuned for more!

This video is incredibly resourceful. I'm using this to study for my Behavioral Neuroscience Exam. Thank you, and I like your accent.

When you said than the horizontal cell is inhibiting the cones or rods, what neurotransmisor is acting???...

@Mansuya If you watch the video again, you will see an example of what I mean. When I put the two rectangles together, you should see one becoming lighter. Watch it carefully.
