Hi! This video is awesome. I recommended it to my sister in law, she's a doctor, and she is showing it to her students. I hope you will come back and create more content! Good stuff!
The way our neurons are connected always takes me on a mindblowing trip. To think we have so many inhibitory and interconnection neurons that serve as a buffer to make our responses more adaptive and complex ALWAYS brings a smile to my face like "Phew! There's still SO MUCH to learn" Thank you for this video! Definitely subscribing. :) Good day to ya!
What you explained is the 'shape hypothesis' but you missed the 'vibration hypothesis ' It explains why chemicals with different shapes smell similar using Quantum tunneling.
Totally true - I'm still not sure whether I should have included the vibration hypothesis, or other details (like how the adaptation to smell happens, or that not all neurons that descend into the olfactory bulb synapse onto the interneurons)...
Can you provide examples of molecular shapes/ types of smells? You said there are about 500 categories of smells for humans, so, for example, is "sour" one of those categories or a combination of those categories? Is there one basic molecular shape that elicits the smell "sour"?
