Here’s something you don’t see every day:
From the video description:
A simple plus/minus 1V signal from a beat-heavy song can be used to stimulate the motor neurons in the leg of a cockroach. This is an example of such.
Using setups like this can help us understand how neurons and muscles work, and can assist us in understanding our own nervous systems.
I’ll tell you what else this helped me understand: we’ve reached such mastery of nature that we’re now just having fun with it. I’m not sure if this is good or bad, but the above example is certainly a bit macabre.
