H03 NERVE CONDUCTION - MP36/35 This PRO lesson describes hardware and software setup of the BSL PRO System to record and measure NERVE conduction velocity along the ulnar NERVE of a human subject. EXPERIMENTAL OBJECTIVES To record a charge from the stimulus electrodes to recording electrodes. To observe the Threshold, Maximal and Supra-Maximal response levels. To determine NERVE conduction velocity along the ulnar NERVE. TASKS PERFORMED BY THE STUDENT Subject will stimulate the NERVE at increasing and decreasing

a dissected frog sciatic nerve. For a specific procedure on isolating and removing the frog sciatic nerve, please refer to PRO Lesson A01 Frog Preparation . EXPERIMENTAL OBJECTIVES To record the CAP of the frog sciatic nerve and measure the latent period. To record the effect, on the amplitude of the CAP, of subthreshold, threshold, submaximal, maximal, and supramaximal stimulation of the sciatic nerve. To determine the average nerve conduction velocity. To observe and record nerve refractoriness by stimulating the nerve using maximal stimuli of increasing frequency. To record the effects of temperature on the

in axons through the ventral nerve cord. The cerci have hundred of tiny hairs connected to individual mechanoreceptors. The small hairs respond to touch and small changes in air currents. The cockroach uses this information to evade predators. In this lesson, stainless steel needle electrodes are placed under the cockroach ventral nerve cord to record the nerve response to stimulation. A puff of air is presented to the cerci and the response is recorded. This particular lesson shows the information being passed along the ventral nerve cord. The axons traveling through the nerve result in amplitude data spikes during recording, allowing one to study this
