Products Description
YJ-EEG16/24/32 Quantitative Electroencephalogram
An electroencephalogram (EEG) machine is a sophisticated medical device that records spontaneous electrical activity in the cerebral cortex.
It collects weak bioelectrical signals from the scalp through electrodes, and after amplification, filtering, and digital processing, generates an electroencephalogram waveform for clinical diagnosis and neuroscience research.
Electroencephalography (EEG) machines are based on the bioelectrical phenomena of neurons: when neurons are excited, the transmembrane flow of ions generates a potential difference (action potential), which is transmitted through synapses to form clustered rhythmic electrical activity.
Electrodes capture changes in scalp potential (typically only 2–200 μV), which are then amplified (gain >100 dB) and filtered (to remove power frequency interference, electromyographic noise, etc.) before being converted into digital signals for analysis.
Application scope:
Disease Diagnosis
Epilepsy: Detecting abnormal discharges such as spikes and sharp waves.
Brain Injury and Tumors: Localizing lesions (e.g., increased localized slow waves).
Sleep Disorders: Analyzing EEG changes during sleep.
Functional Assessment
Anesthesia Depth Monitoring: Adjusting anesthetic dosage based on EEG fluctuations.
Brain Death Determination: Confirming the absence of electrical activity.
Research and Emerging Fields
Brain-Computer Interface (BCI): Decoding thought-controlled external devices.
Neuromarketing: Analyzing EEG responses during consumer decision-making.
