I was in the neurosciences before my current direction, as mentioned in the earlier post, the topics is neuroplasticity. It doesn't correlate to a mbti function at all, and I'd advice a more broad / less mbti focus when dealing with real sciences.
Its essentially the ability of parts of your brain to pick up tasks from another part
Here is an example here
Extraordinary Brain: Woman's Missing Cerebellum Went Unnoticed for 24 Years
"the cerebellum, which means "little brain" in Latin, is responsible for coordination and fine movements, such as the movements of the mouth and tongue needed for producing speech. People with damage to this brain area typically experience debilitating motor difficulties. Yet contrary to the doctors' expectations, the Chinese woman's absence of the cerebellum resulted in only mild to moderate motor problems and slightly slurred pronunciation, according to the researchers. "This surprising phenomenon," demonstrates the plasticity of the brain early in life, they wrote.
"It shows that the young brain tends to be much more flexible or adaptable to abnormalities," said Dr. Raj Narayan, chair of neurosurgery at North Shore University Hospital and Long Island Jewish Medical Center in New York, who wasn't involved with the woman's case. "When a person is either born with an abnormality or at a very young age loses a particular part of the brain, the rest of the brain tries to reconnect and to compensate for that loss or absence," Narayan said."
Genetics literally determines everything in regards to what you are capable of. The plasticity of your brain is also genetically determined, but its a way of allowing our brains to adapt to the environment without having to change our genetic code. Whether that means becoming more violent to stay afloat in a physically aggressive environment (brain reconnecting violent impulses to match environmental needs), limiting function lost from injury and passing onto a healthier segment of the brain, etc.
