Really enjoying the class!!! Enjoyed making my first XOR gate✨.
Starting week 2 of the UCSF Cellular Electronics Minicourse - building logic gates with transistors, in order to better understand how logic can be implemented with proteins and DNA.

12/.Final thought:. We spend years learning vector math in school. Fruit flies are born doing it. Feeling inspired… and slightly outperformed by an insect. Thanks, Dr. Maimon, for the brain-bending talk!.🧠💡.#ScienceIsCool #VectorMathInNature.

11/.This is how math, neuro, and imagination come together to fly. 🚀.Literally. #NeuroTwitter #FlyNeuroscience #AlzheimersResearch.

10/.This could help scientists understand memory, navigation, and even cognitive decline in diseases. And all of this came from a setup where flies were strapped into virtual reality like little Top Gun pilots.

9/.Why does this matter?.Because disorientation is one of the first signs of Alzheimer’s. 🧠🗺️. Understanding how even a tiny fly brain tracks direction could unlock insights into how our own brains build a sense of space—and what happens when that system breaks down.

8/.They even manipulated the vectors and watched the output change exactly like in physics equations. This is not a drill. 🚨. This is neurons doing real math. Insects are humble, but their brains are anything but.

7/.The most wild part?.This isn’t just metaphor. The neurons literally do vector math. Waveforms of activity represent direction and magnitude—like your calc textbook came to life and buzzed past your ear. Yes. Vector math in a fly brain.

6/.Each of 4 classes of motion-sensitive neurons acts like a vector:.📐Angle = direction.📏Length = speed. Then the brain rotates these vectors to align with the sun (yes, really), and adds them together. ➕➕➕➕.Fly brain = Math genius.

5/.So, how do they compute this direction of travel?.Hold tight, this is where it gets ✨mathy✨. The fly brain breaks motion into 4 axes. Think vectors. Like a physics student plotting movement on X-Y axes. But the neurons… ARE the vectors.

4/.They call it:.Travel-Direction Neurons 🧠➡️🌎.Not only do these cells signal where the fly is actually moving, they do it in a world-centered reference frame. Like "I'm going north," not "I'm facing north.".Compass mode: ON 🧭.
