Episode notes
Brain's Physics Engine
- Reaching for objects involves complex physics problems that our brains solve effortlessly.
- We take this ability for granted, but it's a remarkable feat of neural computation.
Key Information for Movement
- Grabbing an apple requires two pieces of information: the apple's location and your hand's location.
- Your brain constantly processes this information to guide your movement.
Nose Touch Test
- Try touching your nose with your eyes closed; it's easy due to sensory feedback from your body.
- Touching an external object with closed eyes is harder; your brain relies more on visual input for its location.
