The TLC7 Assessment
Most trainers agree that clients respond best to training plans customized to their existing brain patterns. The TLC7 Assessment of Brain Patterns is a practical, cost-effective tool that allows brain trainers to receive detailed analysis of relationships within the brain using the same BioExplorer or Infiniti software and same amplifier they use for training. Results are obtained in a matter of seconds.
The TLC7a version of the Assessment automatically artifacts your data, while allowing you to change those decisions if necessary.
The TLC7 takes 45-60 minutes to complete. It can be done by professionals or home-users. Recordings are made at six pairs of key sites, eyes closed (EC), eyes open (EO), and performing a mental task (TSK). An additional 3 pairs of optional sites can be added as the trainer wishes.
The Analyze page (small section shown here) summarizes findings from the full assessment and identifies in a single display the training categories that suggest potential problem areas. Red numbers indicate values higher than expected, blue numbers values lower than expected.
Frequency Distribution Maps
Maps show the % of brain activity at 10 key frequencies around the brain and how patterns change in eyes-closed and eyes-open resting states and at task.
These can be helpful in getting an overview of the brain’s “style” and identifying areas where there may have been injuries or damage. Brighter colors represent higher percentages of total EEG at a site in a particular frequency.
Heads Display of Absolute and Relative Amplitudes
The Heads displays array data around the head, color-coded by frequency, to make it easier to compare absolute values (left head) and relative values (right head).
By clicking the buttons at the bottom of the page, the trainer can see data for Eyes Closed, Eyes Open or Task. This page is especially helpful in comparing beta or alpha values between sites, and for judging overall levels of fast activity.
Histograms compare left and right amplitudes in 10 frequency bands for each brain area during eyes-closed, eyes-open and challenge conditions. With the click of a mouse, the graphs can add or remove conditions—or even focus on one hemisphere.
There are three histogram pages. The Amplitude histograms, a portion seen here, show the distribution of amplitude among all frequencies at each site. Symmetry issues and reverse activation are easily seen.
The Variability histograms show, for each site, the amount of amplitude variation in each frequency band during each of the three conditions. High levels of variability indicate limited control. Brains showing extremely low variability may suggest excessive control.
The Symmetry histograms show differences in amplitude between the two members of a site pair in each frequency in each condition. Generally amplitudes should be symmetrical between site pairs. Small values indicate symmetry, large values suggest Channel 1 (large positive) or Channel 2 (large negative) is dominating.
The Report pages are color-coded tables of important data. Measures are arranged so that red numbers suggest readings higher than expected and blue numbers suggest readings lower than expected. Data is given for all sites under all three conditions.
The Report page, a portion seen here, provides frequency band ratios known to be important, such as the Beta/Theta and Alpha/Theta ratios. The peak frequencies within the middle, fast, and overall bands are also shown.
Synchrony is the brain’s ability to communicate efficiently within itself. The Synchrony page shows levels of coherence and phase locking between the two members of a site pair, e.g., left and right front, for all frequencies, sites and conditions. High levels of fast-wave coherence or low levels of slow-wave coherence are identified with color coding.
