That your brain continually learns and evolves is not surprising at all.
What is surprising is that the location of the subset of neurons that reacts to a specific thing (say the smell of wine) changes over time. So neurons that were used to identify the smell of wine at time T, might be doing something completly unrelated 6 months later, and the task of identifying wine smell is now handled by another subset of neurons in the brain.
It is surprising and on the surface seems ineficient since your brain has to continually transfer knowledge from one region to another rather that just ajusting the existing region to new learnings.
- rantwasp 5y agowe are making a big assumption here: that neurons have tasks and are responsible for X. What if a neuron (actually a cortical column) could learn thousands of X and fire only when specific environmental conditions are met? What if you constantly wire and rewire the connections between neurons? What if multiple areas can do some thing and they arrive at a conclusion through consensus? what if your brain can predict a lot of things and just discards sensory input when it matches the expected prediction?
