EEG With the Brain

Assessing Brain Activity

At Central Florida Neuropsychology we assess brain function through neuropsychological evaluation and brain activity through the Quantitative Electroencephalograph or Qeeg. This involves a non-invasive procedure where we record a computerized EEG and submit it to specialized analysis. By assessing both brain function and brain activity we can correlate the two in order to develop a program of intervention which addresses both behavioral manifestations of brain activity and abnormalities in the activity itself.

Analyzing Brain Activity

In short, computerized EEG with Brain Mapping is a procedure that records electrical activity within the brain from 24 channels. This tool gives us the ability to view the dynamic changes taking place throughout the brain during processing tasks (such as reading or while doing mental math) and assist in determining which areas of the brain are not fully engaged and processing efficiency. Over the past 30 years, a method of QEEG analysis called Quantitative analysis with database comparison has been developed.

Quantitative analysis aids in more precise identification of subtle brain dysfunction. It provides information about the functional organization or disorganization of the brain and serves as a basis for identifying variations in brain function that are associated with different types of neurological disorders including Attention Deficit Disorder, Depression, Dementia, , Obsessive/Compulsive Disorder, Specific Learning Disabilities, and Traumatic Brain Injury to help ensure that the true underlying dysfunction is addressed rather than just the behavioral, cognitive or emotional manifestations.. This process is used in select hospitals, clinics and research centers around the world, and Central Florida Neuropsychology is proud to be able to offer this state of the 2 rt procedure in Highlands County.

At Central Florida Neuropsychology we use this more objective, accurate and detailed information to create more effective neurodevelopmental training protocols. This EEG with quantitative analysis, comparison to a database of individuals with normal brains and brain mapping provides us a baseline to work from while we retrain the brain.

Electrical Activity

The electrical activity of the brain behaves like any other electrical system. Changes in membrane polarization, inhibitory and excitatory postsynaptic potentials, action potentials create voltages that are conducted through the brain tissues electrically within each cell and chemically between cells. These electrical voltages enter the membranes surrounding the brain and continue up through the skull to the scalp where we measure them in microvolts.

These potentials are recorded by electrodes that are is attached to the scalp via a stretchable cap with non-toxic conductive gel. The electrodes are fed into a sense amplifier. At Central Florida Neuropsychology, the EEG is recorded from many electrodes arranged according to the international 10/20 standard for describing these positions.
