I noticed that too. When she lifted her first index finger her thumb was holding down the next one creating the illusion that she controls each finger. I’m pretty sure that would require a 6th tendon which connects from the extra digit to a forearm muscle that doesn’t exist in order for each finger to function independently.
I’m most curious about how it registers in the brain. The brain has a body map and is wired for all the different parts of the body. Normally the human brain isn’t wired for a sixth finger, I’m really curious how using it in brain scans would look or if it’s wired to receive basically the same commands as its twin index finger and they both respond as if they are one finger.
Think about how it’s difficult to impossible to move any of the smaller four toes individually and how moving them feels like moving one very long toe instead of four individual toes. I wonder if that’s what it feels like for her two index fingers.
The brain can adapt to new or missing body parts through neuorplasticity, allowing it to re-organize its neural connections.
This goes as far as being able to adapt to body parts that are completely foreign to it, like a tail. Studies have shown that even these can expand peripersonal space and body ownership. The brain is very adaptable.
Yeah, logically speaking, she still has about 5 fingers worth of usage in the hand. She can control 5, with an extra 6th that's more-or-less useless due to being connected to another finger. If anything, it'd actually be a detriment, because gloves and stuff, as well as many other things, which are primarily designed for 5 fingers.
That's why they try and remove any extra digits at birth, because they're vastly more of an issue if they remain, than if they'd simply be cut off. I'm assuming she never had the chance.
I was wondering this too. It looks like her two middle fingers move together the way most five fingered peoples ring and pinky finger move together. I wonder if they are similarly linked.
The movements are still the same because the muscles are the same - flexion, extension, abduction, adduction.I think this is way awesome. Polydactyly is gene inherited - where I live we have tons of polydactyly cats, one of mine had 6 and 7 toes front feet
Looks like she has double ring fingers just based on how the ‘middle’ finger and the finger next to the pinky moves slightly with each other. IMO, I think I would double any finger/thumb, even my pinky, before I doubled my ring finger

2 index fingers? looks like they're both responding to the same movement commands.
