According to Wikipedia, "Neuroplasticity" means, essentially, "the ability of the brain to change throughout an individual's life, e.g., brain activity associated with a given function can be transferred to a different location, the proportion of grey matter can change, and synapses may strengthen or weaken over time."
Of course, humans are born with this ability; it's a feature of how the brain works. Unfortunately, neuroplasticity typically will decrease with age. Additionally, research has shown that older humans who keep their minds active, (exercise helps as well), with novel stimulation, are quite capable of growing new synapses, creating new interconnections between neurons, further convolution, and even remapping cells to compensate due to injury or disease.
The "cerebral cortex", (the outer surface of the brain), is very convoluted, (or wrinkled), to allow the maximum amount of brain neurons to fit inside the human skull. These convolutions increase the surface area to allow for more neurons, allowing additional power for processing information.
Various types of neurons include Sensory neurons (gathering stimulus from the sensory organs and sending signals to the spinal cord or brain), Motor neurons (controlling muscle contractions and glands, for example), and Interneurons (connecting neurons to other neurons).
Research has shown that "Intelligence", (the capacity for logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem solving), correlates with overall brain volume, grey matter volume, and neural efficiency, among others.
What's my point in 'splaining this in a blog?
My point is that it's never too late in life, (or too early), to have interesting, new or unusual experiences, which keeps the mind growing!
I believe there are many ways to do this, from doing crossword puzzles, to hiking in the woods. It all counts. Even consuming cannabis, (or perhaps an occasional psychedelic?), fits this definition.
So be free and grow your mind. Use Neuralplasticity to your benefit! Keep your mind active! Do new and exciting things in your life! We all benefit in Society when our Citizens are expanding their minds!
One of my favorite ways of keeping my mind active and growing is the game of GO. (I will be discussing my lifelong interest in Go, and how it relates to life, in further blogs. Stay tuned!)
