What Is the Electroneurophysiology Laboratory? / What Is Its Purpose?
Üsküdar University Electroneurophysiology Laboratory is a modern simulation center providing clinical and practical training in the use of advanced technology devices that measure the electrical activities of the central and peripheral nervous systems.
- Main Purpose: The main purpose is to enable students in the Electroneurophysiology program to gain the competence to perform electrophysiological tests (EEG, EMG, PSG, etc.), which are vital in the diagnosis of neurological disorders such as epilepsy, sleep disorders, muscle diseases, and nerve compression, in accordance with international standards and without errors.
- Academic Contribution: The laboratory transforms theoretical knowledge of neurology, anatomy, physiology, and electrode placement protocols into practical manual skills. It develops students' reflexes regarding appropriate patient approach, artifact (signal noise) prevention, and maximizing the quality of clinical recordings.
Devices and Technical Equipment Available in the Laboratory
The laboratory infrastructure contains industry-standard diagnostic and measurement equipment used in neurology clinics and sleep centers. Within the scope of its Key Features, the laboratory equipment includes:
- EEG (Electroencephalography) Devices and Caps: Recording units that record the electrical activity of the brain (brain waves) from the scalp through electrodes, with recording procedures compliant with the international 10-20 electrode placement system.
- EMG (Electromyography) Measurement Stations: Systems that measure the electrical conduction velocities, reflex responses, and motor/sensory action potentials of muscles and the peripheral nerves that stimulate these muscles.
- PSG (Polysomnography / Sleep) Simulation Equipment: Multichannel sleep examination units that enable the simultaneous recording of brain waves, eye movements (EOG), muscle tone (EMG), respiratory activity, and heart rhythm (ECG) during sleep.
- Evoked Potential (EP - VEP, SEP, BAEP) Modules: Additional hardware modules that enable the measurement of the brain's electrical responses to visual, auditory, or sensory stimuli and the integrity of neural conduction pathways.
- Electrodes, Paste, and Conductive Gels: Electrode sets with silver/gold coating and medical consumables used to improve signal quality and reduce skin resistance (impedance).
Research and Application Areas
The applied course curricula carried out within the laboratory cover all neurological testing processes that an electroneurophysiology technician may encounter in professional life:
- Routine and Sleep-Deprived EEG Recordings: Selecting an appropriate cap for the patient, applying paste, placing electrodes, and recording brain waves by applying activation methods such as hyperventilation and photic (light) stimulation.
- Nerve Conduction Studies (EMG Preparation): Electrically stimulating peripheral nerves (median, ulnar, sciatic, etc.), adjusting the stimulation current intensity, and analyzing potential waveforms.
- Polysomnographic Sleep Scoring: Practicing the digital scoring of sleep stages (REM, NREM), respiratory events (apnea/hypopnea), and leg movements in simulated patients admitted to the sleep laboratory.
- Impedance and Artifact Analysis: Identifying and eliminating methods of electrical interference that impair recording quality, such as muscle contraction, sweating, eye blinking, and the effects of surrounding devices.
Contributions to Students and Industry
The Electroneurophysiology Laboratory provides highly qualified professionals to the sector by minimizing the device orientation periods students require in hospital environments after graduation.
- Clinical Communication and Confidence Discipline: Students personally experience and learn the proper electrode attachment and patient comfort techniques, as well as clinical ethics, for sensitive patient groups such as individuals with epilepsy or sleep disorders.
- High Employment Potential: Graduates who become proficient in the advanced equipment and recording protocols used in this laboratory can quickly find employment as Electroneurophysiology Technicians in state hospitals, university hospitals, private hospitals, sleep disorder centers (sleep laboratories), psychiatric clinics, and clinical research centers.
