QEEG BRAIN ASSESSMENTS

            

During your brain assessment, we record the EEG activity of your brain at rest and on task using a standardised 19-sensor-EEG cap placed on your head. This recording is a safe and non-invasive procedure.

We then carefully inspect the collected raw EEG data, process and analyse it with the help of cutting-edge clinically validated neuro-algorithms to identify patterns of cortical activation and suppression, to capture neural network connectivity and to evaluate individual’s information processing style.

Subsequently, we review the results of this in-depth analysis in the context of your goals or symptoms and design a personalised neuroprogramme, integrating neurofeedback training and selected non-invasive brain stimulation methods.

Your results are often visualised in several modes – most frequently these are raw EEG waves, 2-D surface brain maps and a 3-D swLORETA deep brain imaging.  

INDEPENDENT COMPONENT ANALYSIS

Independent Component Analysis (ICA) is a signal processing method to separate independent sources linearly mixed in a signal. For instance, in the electroencephalogram (EEG), ICA can separate out artifacts embedded in the data (since they are usually independent of each other). ICA can also help identify the independent cortical and subcortical sources contributing to the raw EEG signal measured on the scalp. In addition, we use ICA to analyse Event Related Potentials extracted from EEG data on task.

EVOKED POTENTIALS AND EVENT-RELATED POTENTIALS

As a part of our brain assessment, we may investigate the speed and patterns of information processing in your brain, while you perform a computerised speed-accuracy task. The brain responses to the stimuli, or events included in the task are revealed and visualised with the help of the most advanced MATLAB neuroscience software packages currently available.

The qEEG brain assessment also provides an opportunity to meet your neurotherapist in person and to answer any questions you might have regarding the process.
