Leg Neurophysiology Recordings

Raw data of 8 legs recorded. The left, metathoracic leg from 8 cockroaches was removed via a transverse coxa cut. One stainless steel “map pin” electrode was inserted into the coxa, the other map-pin electrode in the tibia/tarsus joint, and the electrodes were plugged into a “SpikerBox” Neural Amplifier. 10 seconds of spontaneous activity were recorded, followed by 10 seconds of lightly tapping the prominente barbs on the tibia of the cockroach leg with a plastic probe. After this measurement, the electrode that was in the coxa was then inserted into the center of the femur, and the same recording procedure repeated (10 seconds of spontaneous activity followed by 10 seconds of light touch). Finally, the coxa was then removed with forceps, the electrodes left in place, and the recording procedure repeated once more. The three electrode conditions are separated by periods of silence in the .wav files.
