VSHS students experienced EEG recording in a laboratory environment

An event titled “EEG from a Biomedical Perspective: Device Introduction and Applied EEG Recording” was organized by the Üsküdar University Vocational School of Health Services (VSHS). In the practical workshop, students had the opportunity to closely examine the EEG recording process and learned about brain wave recording, the operating principles of EEG devices, and points to consider during recording.

The workshop, held in the VSHS Electroneurophysiology Laboratory, was organized under the guidance of Instructor Mehmet Kavacık, Head of the Dental Prosthetics Technology Program, and Instructor Recep Yılmaz, Electroneurophysiology Laboratory Supervisor.

Students gained knowledge about how the brain's electrical signals are recorded by the device and transferred to the screen, by practically observing the stages of EEG recording.

Signals from the brain are recorded via electrodes

Instructor Mehmet Kavacık and Instructor Recep Yılmaz, explaining the operating principle of the EEG device, stated that the signals received from electrodes placed on the scalp are amplified and converted into data.

Brain waves provide information about a person's brain activity

Instructors pointed out that EEG recordings are not merely about displaying brain waves, but the obtained data is used in evaluating a person's brain activity.

EEG recording duration varies according to the patient's condition

Instructors, stating that the duration and methods applied in EEG recording vary according to the patient's clinical condition, also provided information about standard EEG recordings, as well as sleep EEGs and long-term recordings performed during surgical procedures.

Correct evaluation of artifacts is important for diagnosis

It was stated that situations such as the patient swallowing, eye movements, and speech during EEG recording can appear as artifacts in the records. It was emphasized that noting these types of movements during recording is important for the doctor to accurately evaluate the data.

Information was shared that alpha and beta waves are prominent during wakefulness in adults, while delta waves are generally seen during sleep and in infants. Instructors also reminded that EEG recording alone is not sufficient for a definitive diagnosis, and the obtained data should be evaluated together with the patient's clinical findings and other examinations.

The workshop concluded after students' questions regarding EEG recording and brain waves were answered.
