What is QEEG Brain Mapping?
QEEG (Quantitative Electroencephalogram) Brain Mapping is a procedure that records electrical activity within the brain from 19 locations on the scalp. Very similar to the Electrocadiogram or EKG which measures electrical activity of the heart at the surface of the chest, the QEEG measures electrical activity of neurons or brain cells at the surface of the scalp.

Brain Mapping is safe & non-invasive
QEEG is a safe and non-invasive assessment. Sensors are first placed on the surface of a person's scalp. Then, EEG activity is measured under different states and tasks that a person frequently encounters: eyes closed, eyes open, reading, writing, listening, and doing arithmetic.

What Is It Used For?
At Spectrum Learning, Brain Mapping is not meant for diagnosis of conditions, but for analysis of a person's brainwave pattern while he/she is engaged in specific tasks . Besides the standard tests of having eyes open and closed, tasks in which the child has difficulty in engaging will be given. For example, a child with dyslexia will be given various reading tasks. On the other hand, one with cerebral palsy will be asked to do hand or leg movements to identify areas of brain activation while executing the task.

A Guide for Training Locations for Neurofeedback During QEEG analysis, we will examine in detail the charts produced during the Brain Mapping test. Through this, we will be able to identify the changes taking place throughout the brain while engaged in different tasks. This tells us which areas of the brain are fully engaged and processing efficiently and which are not . These areas are then translated into training protocols for Neurofeedback. Thus, Brain Mapping serves a map to guide us in determining specific locations to train during Neurofeedback. This leads to more effective Neurofeedback training and ensures that specific objectives are met.
