A colleague pointed me to this neuroscience video of the week. Completely logical but still a bit stunning, a famed banjo-picker does his thing as brain surgeons place electrodes inside his head to stop his tremors. [BBC video, so it has a short ad preceding the good part]
I’ve seen this surgery now with severely depressed people, who describe a great weight lifting from their minds when the electrodes hit a good spot, and with people with Parkinson’s disease, when the good spot is one that stems their shaking. But somehow, the banjo makes it all seem new again.
