QEEG BRAIN ASSESSMENTS

            

During your brain assessment, we make an EEG recording of your brain at rest and on task using a standardised 19 sensors EEG cap placed on your head. This recording is a safe and non-invasive procedure. The collected raw EEG data is then visually inspected, processed and analysed to reveal the state of vigilance, the patterns of cortical activation and de-activation and the individual information processing ability and biases. We then review the results of this analysis in light of your goals or symptoms and suggest neurofeedback training and non-invasive brain stimulation options suitable for you.

The 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 waves measured on the scalp. ICA is one of the methods we use at Bright Brain Centre to separate CNS activity from physiological artefacts of non-cortical origin. In addition, we use ICA to analyse Event Related Potentials EEG data.

EVOKED POTENTIALS AND EVENT-RELATED POTENTIALS

As a part of our brain assessment, we investigate the speed and patterns of information processing, while clients perform a computerised speed-accuracy task. The Event Related Potential responses are electrophysiological responses of the brain to external stimuli or events.

NEW! Compendium of selected computerised neuropsychological tests for assessing ATTENTION, COGNITIVE FLEXIBILITY, MEMORY, MENTAL AGILITY and EXECUTIVE FUNCTIONING and for tracking improvements as a result of the brain training and neuromodulation sessions at the BRIGHT BRAIN CENTRE LONDON.

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.
