Unlocking the Power of Brain Waves

Brain Mapping, also known as Quantitative Electroencephalography (qEEG) is a non-invasive procedure that provides valuable information about brain function and can assist in diagnosing various neurological and psychiatric disorders. The electrical signals represent the summed activity of millions of neurons firing in synchrony.

The process of performing a qEEG typically involves several steps:

The patient's scalp is prepared by cleaning and applying a conductive gel or paste to ensure good contact between the electrodes and the skin. Electrodes are placed on specific locations on the scalp according to the International 10-20 system, which is a standardized method for electrode placement in EEG recordings.

Quantitative Electroencephalography (qEEG) works by recording electrical activity from various regions of the scalp using electrodes. These electrical signals represent the summed activity of millions of neurons firing in synchrony. 

The EEG recording is then performed while the patient is either resting with their eyes closed or performing specific tasks, depending on the purpose of the evaluation. The recording may last anywhere from a few minutes to several hours.

The electrical signals picked up by the electrodes are amplified and recorded using specialized equipment.

After the recording is complete, the EEG data is analyzed using specialized software. This analysis includes identifying different frequency bands (e.g., delta, theta, alpha, beta, gamma) and assessing their amplitudes and coherence across different brain regions.
