From Fortune: Not so long ago, conventional wisdom among neuroscientists held that the human brain was doomed to deteriorate with the passage of time, and there wasn’t much anyone could do about it. Instead, a raft of recent studies, aided by brain-imaging technology, all point to a much different conclusion: Our grey matter can keep on regenerating throughout life, producing new active cells all the time. “Your brain is a living and constantly developing dense forest with billions of neurons and synapses,” says Alvaro Fernandez, founder and CEO of market research firm SharpBrains.
The emerging science of neuroplasticity, which studies how our brains change and adapt, is revealing that, as with muscles, it’s a case of “use it or lose it,” he adds. “Once new neurons appear in your brain, where they stay and how long they survive depends on how you use them.”
