Certain layers in the hippocampus get measurably thicker due to increased synaptic connections involving both the dendrites of "receiving" neurons and the terminal buttons of "sending" neurons. And even without getting thicker by adding new synapses, neural circuits that are particularly busy due to the flows of mental activity become more sensitive and influential in the brain as a whole through increased sensitivity of existing synapses, and alterations in gene expression. It's pretty exciting to learn more and more about how the mind can change the brain. -Rick Great question!

Are there new neurons formed, new dendrites, axon, synapse? Is it possible that the neurons along with all of its part become thicker or take on new characteristics with use?
