Some Brain Connections are Not Complete until Your 20s

Myelination Do you know that some brain connections are not complete until your 20s? The process is called myelination. It is the coating of neurons with a chemical insulator which makes a signal travel along it up to 100 times faster. There is signal regeneration at the nodes of Ranvier. The effect is similar to…

Almost Gate

Central neuron getting very similar signals, treats them the same

… the neuron’s Almost Gate can be opened by different inputs and yet deliver the same output to downstream neurons

Two Methods of Thinking

Pattern-matching, like analogy, where we treat partial matches like exact fits. It’s possible to make errors. It’s possible to jump to a good answer without complete information. This is the source of much intuition and creativity.
