“The central nervous system is made up of the brain and spinal cord. The spinal cord comprises a bundle of nervous tissue and support cells that send messages from the brain to the rest of your body. But did you know that, on average, the spinal cord ceases growing at four years of age?

And while the brain may be done growing by your teenage years, it is not considered fully developed until your mid-to-late 20s. That’s because the prefrontal cortex, responsible for planning, prioritizing, and impulse control, is one of the final regions of the organ to mature. This helps explain why teens are more likely to make poor decisions and engage in potentially harmful behaviors without considering the short or long-term risks involved.

Additionally, once your brain is fully developed, it may become more difficult to accept new ideas and change behavior. Although the reasoning isn’t completely understood, research has shown that while adolescents see increases in social vitality and openness measures, these decrease with age.

It’s a myth that you only use 10% of your brain. Rather, neuroscience confirms that the brain is always active and firing even when you’re sleeping. Another common fallacy is that brain size determines how smart you are. Intelligence is determined by the number of synapses (or connections) between brain cells, not by brain girth.

Have you heard the myth is that the brain breaks down with age?  Well, know that some cognitive functions, such as memory, may decline as you get older, other mental skills, such as comprehension, vocabulary, conflict resolution, and emotional regulation, can improve. And research has shown that when the elderly keep their minds active by exercising their brains with crossword puzzles or games like Sudoku and bingo, their intelligence may also increase.”
