BIOPAC announces a Programmable Stimulation System for E-Prime to control stimulus frequency and stimulus intensity for real-time stimulus delivery changes based on a subject's responses. The system includes a Constant Current and Constant Voltage Linear Isolated Stimulator (STMISOL), USB 4-ch D/A Unit, software utility for communication between E-Prime and the stimulator, a sample E-Prime experiment with the necessary interface commands to communicate with the D/A unit, and interface cables. The D/A unit provides the stimulator with the appropriate voltage levels to stimulate a subject. The system supports up to four STMISOL and includes one.
The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL500 series disposable electrodes and LEAD131 for a four-spot […]
NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
BIOPAC’s just released Introductory ECG Guide addresses fundamental to advanced concerns to optimize electrocardiography data recording and analysis. Topics include: ECG Complex; Electrical and Mechanical Sequence of a Heartbeat; Systole and Diastole; Configurations for Lead I, Lead II, Lead III, 6-lead ECG, 12-lead ECG, precordial leads; Ventricular Late Potentials (VLPs); ECG Measurement Tools; Automated Analysis Routines […]
