Record EMG to investigate the properties of skeletal muscle. Record and display raw and integrated EMG signals; overlap the signals for better correlation of the data. Measure strength and repeat trials for motor unit recruitment /summation and fatigue. Demonstrate the treppe (staircase) phenomenon. Study the contractility of skeletal muscle with the force transducer and stimulator. The frog gastrocnemius lesson records threshold, maximal response, summation, tetanus, and fatigue.
|Tension Adjusters||The HDW100A tension adjuster operates with the TSD105A and TSD125 series force transducers. The HDW200 adapter allows 3rd-party tension adjusters to interface with BIOPAC Force Transducers. The rugged design and stability of the HDW100A mounting allow for fine position control. The position adjuster is located on the top for easy access and smooth operation. Vertical scales are…|
|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.…|
|Headphones||These wide response high-fidelity headphones are used for auditory stimulus (short tones or clicks) or to listen to physiological signals (like EMG) directly. The headphones are comfortable and lightweight and include a 2-meter cable so the Subject can be seated a comfortable distance from the acquisition unit. Simple Sensor connector interfaces with the “Analog Outport” port…|
|High Impedance Cables||Micro-electrode interface cables for MP36/36R, MP35, MP30, or MP45* These fully-shielded, unity gain, high-impedance, differential input, electrode interface cables permit high resolution recording of biopotential signals. These interface cables incorporates dual ultra-high impedance buffer amplifiers (one for Vin+ and one for Vin-) to allow for connections to needle electrodes, wire electrodes, or very small surface electrodes…|
|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…|
|Lead set, shielded, BSL||This fully-shielded cable assembly permits high resolution recording of biopotentials using our EL500 series disposable electrodes. The 2 meter adapter is terminated with standard pinch connectors to interface with EL500 series snap electrodes. The SS2LB interfaces with Biopac Student Lab data acquisition units (MP3X or MP45) and the MP36R research unit. Compatible releases BSL Lessons…|
|Variable Force Transducer, BSL||The Variable Range Force Transducer incorporates a unique design that allows the transducer to cover a wide range of forces. This makes it ideal for covering a wide variety of applications. Forces are transmitted back to the beam via a lever arm to insure accurate force measurements. The lever arm has a number of attachment…|
