The intake assessment includes a Brain Map, a General Overview of Neurofeedback and Biofeedback. Below is a brief overview of the TLC Assess program, developed by Peter Van Deusen, which we use for the assessment.
Frequency Distribution Maps
How are various frequencies distributed around the
brain? Percent activation maps for each frequency
(alpha maps are shown here) allow you to see how
brain activates from eyes closed to a performance
task in 10 critical areas:
•F3 and F4 •C3 and C4 •P3 and P4 •T3
and T4 •Fz and Oz
This display is excellent for seeing
head injuries (either increased Delta or decreased
amplitudes).
Absolute Amplitude Histograms
What is the activation pattern among frequencies at
each site? These graphs compare left and right
absolute amplitudes for each brain area during
eyes-closed, eyes-open and challenge task
conditions.
There are graphs for each of five areas (frontal is
shown here):
•Frontal lobes •Central
Strip •Temporal lobes
•Parietal lobes •Midline (Fz and Oz)
This display allows you to see symmetry
issues, reverse activation and the distribution of
amplitude among all frequencies at the site.
Heads Display of Absolute and
Relative Amplitudes
What kinds of activation relationships exist between
areas? The Heads displays array eyes-closed data
around the head, color-coded by frequency, to make
it easier for you to identify these patterns at a
glance.
Two heads show absolute and relative values at each
of the 10 sites for each frequency.
Numerical data on amplitudes can be
helpful in determining temporal disconnect,
left/right and front/back reversal patterns as well
as cingulate issues.
Report Page of Ratios, Percents and
Coherences
What kinds of relationships exist in measures other
than amplitudes? The Report page provides ratio and
coherence data at all measured sites for all
conditions.
Theta/beta and alpha/theta ratios,
alpha peak frequency and frequency coherences help
identify critical training issues that don’t appear
in simple amplitude data.
The TLC Subjective Assessment
This Excel-based computer-scored
checklist of 78 potential problems can be helpful in
several ways:
- Provides a ranking of the training categories from the subjective viewpoint of client or family;
- Helps the trainer determine positive and negative persons in the client's support system;
- Gives a comparative ranking of a broad range of issues for each member of the support system;
- Provides a quick, easy tool for performing follow-up rankings after training has progressed;
- Gives a list of the 20 highest-ranked issues to focus interview and discussions on training goals.
