Document Summary
Neurons are not capable of reproduce itself. We accumulated a lot of evidence, the brain is capable of reconstructing itself. Synaptogenesis: neurons can grow if it is synaptogenesis, when you alter this connection, you alter the way neuron connect with another. Brain has a reservoir of stem cells, the stem cells migrating and specifies to add neurons the brain has capacity for neurogenesis into that area in the brain. Your brain is changing itself in order to improve what it is capable of learn. Neurogenesis means the loss of neurons, too. At two years of age, neural pruning happened. To get an area of the brain to work much more efficiently, to improve its performance by killing off neurons. This goes on the entire life, slower when older. It is a machine of machines that can make itself into a new kind of machine. Epigenetic: study of how environmental influence change gene expressions. We thought gene code for certain things.
