<p><pre><code> >This research included the muscular response to opiates and static electricity, for which experiments the spinal cord and rear legs of a frog were dissected out together and the skin removed. In 1781,[5] an observation was made while a frog was being so dissected. An electric machine discharged just at the moment one of Galvani's assistants touched the crural nerve of a dissected frog with a scalpel. The frog's legs twitched as the discharge happened.

Just picturing this wild lab where you've got assistants preparing opiates, dissected frogs layed out with metal wires being attached to them, and spark-generating machines zapping in the background. What a scene, man.

<p><pre><code> > The major drawback of the frog galvanoscope is that the frog leg frequently needs replacing. The leg will continue to respond for up to 44 hours, but after that a fresh one must be prepared.</code></pre>
All throughout reading this article I asked myself just how long a frog leg can be usable, considering nerves decompose quicky. It's answered towards the end with 44h, which is... a lot, and yet almost nothing for what you expect of a tool.
