This Christmas, my parents bought me MindWave, an EEG biosensor which is intended to measure basic brainwaves, mostly around attention and meditation. I actually had my first EEG testing back in 2010, to look for any seizure activity. I had subsequent scans during sleep studies for apnea. This winter, I plan to start some EEG-based neurofeedback treatment at the rehab to learn some self-regulation techniques and possibly map topographic activity within different lobes. I have plenty of pictures showing damage caused by the stroke, but none which show healing. Depending on who you ask, the damaged or dead brain cells on a fair portion of the right side of my brain can no longer serve a purpose. However, there is increasing evidence that merely damaged cells can generate new cells (neurogenesis) and that healthy brain cells can be rewired and recruited to perform activities beyond their original intention (neuroplasticity). For instance, even though the right side of my brain used to control the left side of my body, my current left-side mobility is now presumably controlled by retrained neurons in my left hemisphere. Or, so the theory goes. I may never know for sure. Some might say it's a moot point -- the proof is in the pudding: if I can move my left side, it doesn't matter how or why. It's one of the many ways we are blissfully ignorant of how our bodies manage to function. But I'm curious nevertheless. That's why I'm looking to go down this rabbit hole.
The Mindwave EEG has given me a preliminary picture (below), though I'm certainly not well equipped to interpret this brainwave data:
|Brainwave Visualizer: shows the fluctuating levels of different types of waves.|
Mindwave also includes some games designed to hone attention and meditation skills. Here are some screenshots:
|The Mindty Ant: By focusing on the fruit, you help the ant roll it into his food cache.|
|Mind Hunter: Focus allows the game to target animals, blinking then shoots a bubble that whisks them away (very child friendly).|
|Zombie Pop: You focus on the zombies being made in the zombie factory in order to pop their heads. I haven't yet made it to the level where you actually fight the zombies.|
I'm not quite here yet, but I'm working on it.
My friend Marc -- unaware that I was experimenting with EEG already -- found a perfect non-virtual companion Christmas gift to the Mindwave with a MindFlex he found at GoodWill. It uses EEG focus and relaxation to appropriately speed and slow a fan beneath an accordingly rising and falling foam ball, with an eye toward navigating an obstacle course. Like this:
