How to use the evoked potential system
Evoked potential systems are devices used to record and analyze neural activity in the brain and are commonly used in neuroscience research and clinical diagnosis. Here's how to use it in general:
1. Install electrodes: First mark the location where the electrodes are to be installed on the scalp of the patient (or animal), and then fix the electrodes at the corresponding positions with conductive glue or injection.
2. Connect the electrode: Connect the electrode lead to the recording device, make sure the electrode lead is not broken or damaged before connecting, and connect the electrode lead to the correct channel.
3. Record data: Start the recording device and calibrate it to ensure the signal is recorded correctly. Usually, the recording system collects the potential signal received from the electrode lead and converts it into a digital signal for storage in the computer.
4. Stimulation activities: Stimulate brain neural activity through external stimulation methods (such as light, sound, electrical stimulation, etc.) or internal stimulation methods (such as thinking tasks, etc.), and the recording system will record the corresponding potential signals at the same time.
5. Data analysis: To analyze the recorded potential signals, different signal processing and statistical methods can be used, such as frequency domain analysis, time domain analysis, spectrum analysis, etc., to study and understand the neural activity of the brain.
It should be noted that the use of evoked potential systems requires corresponding professional knowledge and skills, so sufficient training must be carried out before conducting experiments or clinical diagnosis, and relevant ethical and regulatory requirements must be followed. At the same time, the safety and reliability of the equipment and electrodes should be ensured before use to avoid unnecessary harm to patients (or animals).
