TLC Assessment System
Assessment File Downloads and Resources
The files and instructions you need to perform the objective assessment, as well as the subjective assessment checklist, can be downloaded here.
The Assessment can be done with BioExplorer, Infiniti, or Brainmaster 2.0 or 1.9 software. If you are using Infiniti software, you will also need to purchase the CD, Introduction to Infiniti for TLC Assessment, from the Biofeedback Foundation of Europe. The CD provides the implementation you need to gather and export data from Infiniti software into the TLC Assessment.
If you are using BioExplorer, you can also purchase a special version of the objective assessment which guides you in removing eye blink, movement and similar artifacts from the data. Learn more.
Once you have gathered the Assessment data, you can use our ABCD Training Plan Service for expert assistance in determining likely training strategies for your brain and your clients' brains.
The TLC Objective Assessment
The assessment process provides all the information you see here in just 45 minutes, using a number of readily available hardware and software combinations, and it can be done by professionals and home-users alike. You record at five pairs of key sites, eyes closed (EC), eyes open (EO), and performing a mental task (Challenge). Because it is so easy and efficient to do, the assessment can be repeated as often as desired. In addition to the basic assessment, you have the option of recording at four additional important site pairs.
Frequency Distribution Maps
How are various frequencies distributed around the brain? Percent activation maps for 9 frequency bands (slow wave maps are shown here) allow you to see how the brain activates from eyes closed to eyes open to a performance task in critical areas.
This display is excellent for seeing head injuries (either increased Delta or decreased amplitudes). Note for example, the pattern at the right rear for 2-4 Hz, as well as 4-6 Hz.
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. Graph for the frontal area is shown here.
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 143 item checklist can be helpful in several ways:
- Shows you which brain areas are most implicated by the trainee's issues;
- Gives a list of the 20 highest-ranked issues to focus interview and discussions on training goals.
- Provides a ranking of the training issues from the subjective viewpoint of client or family;
- Helps the trainer determine positive and negative persons in the client's support system;
- Provides a quick, easy tool for performing follow-up rankings after training has progressed.
