if you look at what happens in an infant's brain during the first two years there's a tremendous amount of new synapses being formed this is your area by the way you know more about this than I do yeah that's true but then you prune them right there's then the second phase is that you over abundant synapses and now what you want to do is to prune them why would you want to do that well you know synapses are expensive it's talk takes a lot of uh of energy to activate all of the neurons and the synapses especially because there's the turnover of the neurotransmitter and so what you want to do is to uh reduce the amount of energy and only use those synapses that have been proven to be the most important right now
