Measuring Progress with So-Called Objective Tests Speaking of “objective” measures like the TOVA or IVA: I tried both, meaning that I bought them and charged my clients for my use of them for several months one time and a bit less than a month the second time. I’ve thrown the TOVA away twice. The first […]

Neurofeedback: Exercise or Operant Conditioning? I believe neurofeedback is like exercise. In most exercise we have some form of mirror: you might be watching yourself trying to achieve and stay in a pose in yoga, or have a pulse-meter that informs you when you are in or out of the training range in aerobics. There’s nothing innately reinforcing about […]

Coherence Coherence is a measure of how effectively two sites are able to link and unlink, to share information. Whether coherence is a good thing or a bad thing depends to some extent on what frequency we are talking about and what sites and what task. Slower frequencies, alpha and lower, are generally produced by […]

Rewards Rewards in neurofeedback are the alerts the brain receives to let it know that it has done something worth repeating. Rewards are set in the computer’s protocol and usually come in the form of tones, or a video playing, or points accumulating in a game. When I trained with Joel Lubar in the early […]

Deep Brain EEG Measurement The cortex is the “bark” on the outside of the brain–about a quarter-inch thick. There is no “deep-brain cortical structure.” There are a number of structures in the mid-brain which are heavily involved in how the brain works, but there’s a problem. EEG is produced by one (of many) type of […]

Temporals T5 and T6 are on the equator that runs around the circumference of the head from the middle of the valley that crosses the forehead above the supra-orbital ridge, just touching the top of the left and right ears and running through Oz (about 1.5 inches above the inion). They are 70% of the […]

Reassessing at the End of Training If you need an assessment to tell you if the training is working…it’s not. If you are hoping to prove that the training worked with the EEG, you’ll probably be disappointed. The assessment or the QEEG could be done several times over a period of a couple days and […]

Synchrony Synchrony indicates that two waveforms are coherent (consistent relationship between their peaks and valleys) and in phase (peak and valleys happening at the same time in both waveforms). If that is true when you add the waves together, the peaks are added to the peaks, giving the largest possible positive number, and the valleys […]

See Tech Support for information on how to do brain maps. This section is to provide tips for gathering better data. In the TQ guide we recommend that assessments be recorded before 11am. The assessment gives the trainer a starting place. I know what NOT to aim at, and have some ideas as to where […]

Variance/Variability On the variability page of the TQ assessment, the coefficient of variability is the Variance (standard deviation squared) divided by the mean. It shows the number of times that variance is greater than the average, so a higher number means a much more spread-out distribution–less effective control of brain activity in that area and […]
