I wonder if they don't even need to be like traditional body parts like thumbs. Perhaps like octopus tentacles with claws on the end...

#43I broke my Achilles tendon - had to have a FULL reconstruction - they took a tendon that used to help waggle my big toe (the muscle is in my leg) wrapped around my heel and back up my leg and rebuilt my achilles around that - now I have a muscle that used to wiggle my toe than moves my entire foot. How hard was it to relearn? at first I'd try to move my toe and something else would move, it felt weird - but doctor's…
I've been through enough learning cycles to appreciate this but this was a real hurdle for me when I was young because my default was to rely on systems and rules. Ironically as a swimmer my biggest breakthroughs in speed and technique as a teenager were intuition borne out through thousands of hours of repetition but it took me many many more years and a very good piano teacher to conceptualise the art of not conceptualising.

What happened to your toe? Did you loose the capability to move it individually from the others?

I think my realization was that my brain didn't just do simple things, it did complex in many dimensions to adapt and fix things.
The same thing goes with your foot, and it goes way deeper than we realize. It's probably not that one muscle, it is ALL the muscles in the area working together to help you walk. I wouldn't be surprised if there are 50 muscles involved.

#46I started wearing a bath robe belt as a tail and my brain quickly starts telling me I am wearing it when I am not. I also had a phantom watch ⌚ on for a week after losing it.

#48Marshal McLuhan's book Understanding Media had the full title "Understanding media: the extensions of man." And he had a chapter about the automobile. If you've ever had the chilling experience of a skid, the terrifying adrenaline surge during that second where it is clear the car is no longer under your control, you know the dude was onto something. The car is an extension of our bodies. An extra body part.
Another instancee --
In my country growing up we didnt always have "blinkers" on our vehicles (light motorbikes, scooters, bicycles) -- so it was common to use "hand signals" to indicate your intention to turn right or left. I once did "hand signal" when WALKING along a corridor and had to turn right into another corridor / aisle.

#49They put a sensor band around the forearm and used machine learning to interpret the electrical signals the brain was sending.
They were able to interpret intent to move before actual movement. they apparently had a perfect keyboard, but you didn't have to actually move your fingers.
What was interesting is that one of the guys working there had figured out how to have a third arm.
can't find the article. this is close:

The human body is so wild with things like this. What happened to your toe? Did you loose the capability to move it individually from the others?
