Quantitative EEG (qEEG) refers to
signal processing and extraction of features from the electrical
activity in the brain. Many features such as power for specific
frequency bands, coherence among channels, phase differences,
hemispheric asymmetry, and a number of other features are extracted
from EEG activity of the patient and compared to a normative
database. Tables of statistical analysis, topographies and
color-graduated representation of EEG features are generated to help
identify possible disturbances in EEG related to dysfunctions in the
brain. Topographies are commonly used to visualize deviations from
the norm or other features of interest as compared with the
normative database. These features may represent functional
abnormalities in specific areas of the brain and they can aid
diagnostic decisions making and useful in setting treatment
protocols and interventions.
Brain Resource Assessment
Paradigm
- Multimodal Psychophysiological activation tasks
Neuropsychological measures EEG, QEEG, ERP, and autonomic analysis
- Standardized Consistent test battery integrated with
international database
- Cost effective Serial assessments can document progress
- State of the Art Technology and Multidisciplinary Integration
Brain ResourceT
International Database
The Brain Resource International
Database, has an unprecedented standardized integration of brain and
autonomic functions.
Psychophysiological Activation
Tasks
Measures of electrical brain function
over fractions of a second time scale. Selected to tap the brain's
core networks and processes. Brain (EEG and ERP) and body measures
(of electrodermal arousal, heart rate, respiratory rate) are
undertaken simultaneously using non-invasive recording discs placed
on the scalp and skin.
Resting
EEG - Reflects: A baseline of brain and body measures.
Habituation - Reflects:
Brain-body response decrements to novel stimuli, indicative of
automatic learning.
Auditory oddball - Reflects:
Capacity to process relevant whilst ignoring irrelevant information.
Visual tracking - Reflects: Eye
movement and brain function during an automatic tracking task.
< Go-No Go - Reflects:
Capacity for suppressing welll earned, automatic responses.
Conscious and subconscious processing of
facial emotions - Reflects: Brain and body function in
response to emotions.
Visual working memory -
Reflects: Sustained attention and working memory.
Executive maze - Reflects:
Planning, foresight, error correction, visuo-spatial learning and
memory.
Startle - Reflects: The body's
'fight or flight' response.
