Itching to do some homegrown neurophysiology, but don’t have access to the expensive equipment required to perform your experiments? Well, the folks at Backyard Brains might have something for you. They have created the SpikerBox, a $100 device that allows you to listen to and record the neural activity, or “spikes”, in insect legs.
It looks like a pretty neat device, and a great project to work on. I’m guessing it wouldn’t be too difficult to build your own, though- any DIY neurophysiologists out there have some pointers?
