Question

when we don’t learn new things, no new synaptic connection is made? If yes, then the unfired neurons doesn't make any connection between them before we learned something?

Answer 1

Answer:

The human brain keeps changing throughout a person's lifetime. New connections are continually created while synapses that are no longer in use degenerate. To date, little is known about the mechanisms behind these processes. Jülich neuroinformatician Dr. Markus Butz has now been able to ascribe the formation of new neural networks in the visual cortex to a simple homeostatic rule that is also the basis of many other self-regulating processes in nature. With this explanation, he and his colleague Dr. Arjen van Ooyen from Amsterdam also provide a new theory on the plasticity of the brain -- and a novel approach to understanding learning processes and treating brain injuries and diseases.
