Nerve Conduction – Psychophys.

Combine the human-safe stimulating electrode with the stimulator to record nerve conduction experiments. Stimulate the ulnar nerve at three different points and record nerve conduction time. Measure the distance between the stimulation and recording points and then calculate the velocity of signal propagation along the nerve (motor response). Use the finger twitch transducer coupled with nerve stimulation to examine the relationship between applied (external) nerve stimulation and associated motor recruitment.

Name Description Cart
Disposable Long-term Electrodes Small, pre-gelled, electrodes. Most appropriate for long-term ( > 2 hours ) biopotential measurements. The hydrogel base also lends these electrodes to electrical stimulation studies, such as for nerve conduction velocity or tDCS. These disposable, long-term recording, snap electrodes provide the same signal transmission as reusable electrodes, with added convenience and hygiene. Each peel-and-stick electrode…

General-purpose Electrodes These pre-gelled disposable electrodes have a circular contact and are most suitable for short-term recordings, including surface EMG, ECG, EOG, etc. The small vinyl backing allows close electrode placement where necessary, and a slightly less firm adhesive allows "ouchless" removal. The electrodes incorporate liquid electrolyte gel and moderately-high chloride salt concentration for quick, accurate readings.…

Cloth Base Electrodes These disposable cloth base electrodes adhere well and are particularly useful for applications on non-conforming surfaces, such as facial EMG measurements. Due to hydrogel electrolyte concentration, these are also suitable for electrical stimulation studies. Electrodes have a circular contact on a square backing. The adhesive solid hydrogel ensures good contact, and the silver-silver chloride (Ag/AgCl)…

Voltage Stimulators The Voltage Stimulator connects to either the MP36/MP35 or the MP30. BNC output provides compatibility with a variety of stimulator cables. The voltage Range and Level are manually controlled while the pulse timing is user-adjustable and controlled by the Biopac Student Lab software. The Voltage Range (.025-10 Volts or .12-100 Volts) is established by a switch with…

Stim Electrode, Human-safe The Human-safe Stimulation Electrode HSTM01 provides a superior degree of safety and comfort when using a Voltage Stimulator for human stimulation. The ergonomic design allows the user to focus on the electrode placement instead of worrying about holding the electrode. Subjects depress the red safety switch to allow the software-controlled stimulus presentation through. To stop…
