I'm sure new pathways are less likely to be built the older you get, but it is definitely still possible and I believe it's something you can train your brain to do.

Well, what causes neuron paths to develop? Sensory stimuli of any type.

Stimulation of the various senses make the neurons fire, and every time they fire, you are building, extending and repairing neural pathways,

The more input that your brain can receive on a regularly consistent schedule, the better. The more coordinated and less random the stimulation the better. That is why reading, listening, exercising, watching, and talking are all brain builders.

Maybe that's why nearly a half million California Republicans have switched their registration.

all i want to know is when this observation leads to plasticity in pill form... preferably over the counter.

They say you can exercise your brain by playing games like Brain Training for DS and Hot Brain for PSP etc.
Hmmmm, that gives me a few Christmas ideas for my grandparents - even though that's what I want them to buy me! lol

Well, don't forget old school games like Sorry! Monopoloy, and Scrabble. Last month, I saw a very cool Scrabble came that can in a foldup box for travel. I think card games are cool also, especially Yahtzee, Uno, Poker, Gin Rummy, and Canasta. Books and Crazy Eights are cool for kids...and Go Fish! Oops, I forgot Chess, Checkers, Chinese Checkers, and Pool ( well it is a table top board game). LOL
