Listening to Neurons

Just cut off a cockroach leg, hook up the SpikerBox, and listen to the insect neurons firing away (don't worry, they say the leg grows back).

Order yours now! I know everyone in my family would love this, and that soon after I'd be covered in vomit and taken out of the will, divorced, et cetera.

But seriously, have you ever heard of such a thing? Would this work on frogs? Cats? Humans who use their lawnmowers too often when I'm trying to enjoy my garden?

Then again, the demented natural scientist in me thinks this would be neat. I wonder what flowers sound like, if they even have a sound. Which I bet they do.
