I saw an article on somewhere like the Mayo Clinic that was talking about aging and the brain, and they were saying how the brain grows and atrophies according to usage like muscles do. Only not as large, obviously.
Parts of the brain that control different things can grow and atrophy. The article cited a study showing cab drivers in London had a significantly larger hippocampus (I think that’s the part) than the rest of the population.
I don’t know what part of the brain that takes the visual cue and elicits a response in stuff like sports and MA. The visual cortex in the occipital lobe (back of the brain) obviously plays a role, but where the response to that stimulus comes from I don’t know. And I don’t know how much those regions actually grow in size.
There are ways to decrease reaction time in activities. People with traumatic brain injuries have done training that decreases it. Stuff like stuff like seeing patterns on a computer screen and pressing appropriate keys as quickly as possible. Quite often when you’re refining a physical skill what you’re doing physiologically is increasing the synapses; kids learning to write and practicing writing their letters are gaining fine motor control in their hands. They’re forcing their body to increase synapses in their hands - more nerve endings = better control; and possibly in their brain.
Constantly seeing a specific type of stimulus that’s faster and more varied than the norm and reacting to it is a skill. Using baseball as an example, you can develop the perfect swing, but that doesn’t mean you can hit a pitch. You can only learn and refine that through swinging at pitches. Skills like this are refined basically the same way as a kid learning to write - it’s very sloppy at first, then they’re gaining feedback and refining it. They’re visually learning to recognize the error and are practicing and fixing it. This is why they trace letters over and over again at first, then do some freehand, then repeat that for all the letters. While they’re doing this, synapses along the neural pathways are increasing. Where there’s an increase, I’d have to say there’s growth. More increase = more growth. How much actual growth is my question. Synapses are microscopic. Or it could be a figurative re-wiring of the brain.
Too much brain science thinking. I need a mental break
