The Two Types of Neuroplasticity:
Practice Makes Perfect
Taking a New Look at an Old Belief Of course, you will have heard the tired old adage “You can’t teach old dogs new tricks!” Until very recently, everyone thought this was true. Scientists now know that the human brain, which consists of approximately 100 billion neural cells, with trillions of interconnections, can, in fact, generate new pathways—and even new neurons. The old model assumed that you were pretty much stuck with the neurons, pathways and brain you were born with, and that, when a cell died, no new cell grew in its place. We know now that certain areas of your brain can generate new cells, in a process called neurogenesis, as well as generating new neural pathways . In fact, the brain can grow as many as 1,400 new cells in a single day!
