Description
Electrophysiological Acquisition Device (EMG, EEG, and EOG)
An Electrophysiological Acquisition Device is a specialized medical and research instrument designed to record and analyze the electrical activity generated by the body’s muscles and nervous system. This device supports multiple modalities including Electromyography (EMG), Electroencephalography (EEG), and Electrooculography (EOG), enabling comprehensive monitoring of muscular, brain, and eye-related bioelectrical signals.
These devices play a critical role in diagnosing neurological disorders, studying muscle function, evaluating brain activity, and monitoring eye movements, both in clinical and research settings.
Key Modalities
EMG (Electromyography):
Measures electrical signals produced by muscle fibers during contraction and relaxation. EMG helps assess muscle health, nerve function, and neuromuscular disorders.
EEG (Electroencephalography):
Records electrical activity of the brain through electrodes placed on the scalp. EEG is essential for diagnosing epilepsy, sleep disorders, brain injuries, and monitoring brain function.
EOG (Electrooculography):
Detects electrical potential generated by eye movements. EOG is commonly used to study eye motion patterns, diagnose ocular motor disorders, and assist in sleep research.
Working Principle
The device uses surface or needle electrodes to detect tiny electrical potentials generated by the body’s muscles, brain neurons, or eye muscles. These electrical signals are extremely low in amplitude and require precise amplification and filtering. The acquisition system converts these bioelectrical signals into digital data, which can then be visualized, stored, and analyzed using dedicated software.
