Many scientists have opined on the vast complexity of the human brain. Indeed, the neuronal connections in our brains are far more vast than the number of stars in the Milky Way. We actually know little about whole brain function, even in health, but we do know that the brain is highly adaptable. In humans, our brains provide us with the ability to adapt to our environment and to learn. Contrary to previous conception, our brains continue to make connections between nerve cells from birth, and this inter-connected nature apparently serves to reinforce its integrative capabilities. But this is a complex process, and it takes until early adulthood before the brain matures and its structures are in their prescribed space and spatial connection and orientation.
