Experimental setup for nerve stimulation and chemical processing. (a) The Biopac nerve chamber in acrylic (Biopac ®); it features 15 stainless steel pins; each pin is spaced 5 mm apart to provide a variety of recording and stimulation configurations; the sockets accept 2 mm plugs and interface with stimulation and recording cables; the nerve chamber is secured within the polystyrene dark box to prevent environmental light from hitting the nerve. (b) Stimulation and measurement electrodes connected to the steel pins and a rat nerve placed on the pins. (c) The final lab setup: by means of a tube the different solutions for the chemical treatment of nerves can be introduced or extracted without opening the box; wires from the electrodes and the tube are passed through holes in the box wall and isolated by envelopes; the dark box is closed and ready for the experiment.
