During the early years of human development the brain has a greater neural plasticity, that is it has a greater ability to develop and form knowledge in the brain. Over the years as we age our neural "pathways" begin to, in a sense, become rooted in their position. that is they become more concrete and the "pathways" are set in a sense and forming new "pathways" begins to slow/stop at a certain age in development. One of the most intriguing aspects of LSD is that it increases neural plasticity. That is it allows the plasticity for new "pathways" to be created within the brain. Most users report having had revelations on LSD and this would make sense in the fact that, a cortical/"pathway" that may have never developed may have been affected and developed by the experience a user experienced on LSD. In short it is a hypothesis that LSD may increase learning capacity within the brain Biologically by providing for a greater plasticity for cortical/"pathway" development.
