Brain Hacking

My Homemade tDCS Machine

I’ve had an extended break from blog since we visited the rainforest. We are getting some maintenance done and are “stuck” here in Palmas waiting for some parts and some expertise.

I just read an interesting science article (click here)¬†about how a transcranial direct current stimulation (tDCS) device can be used to enhance creativity by “…temporarily suppressing a key part of the frontal brain called the left dorsolateral prefrontal cortex.”

The study showed an increase in creativity when electrical stimulation was applied across the cranium in a particular way. Lots of amateur “brain hackers” have already found this out in an anecdotal sense, and claim even more cognitive enhancements depending on how the brain is stimulated. I know something happens, it did with me in my experiments.

One of my big product ideas was to combine a tDCS and EEG to actually measure the effect of the stimulation and then build algorithms to modulate the stimulation to maximum effect. I wrote about my experiments from a couple years back. Still a great idea and I’d be surprised if someone isn’t trying something similar.
