Stuttering Stuttering is usually a clue that F7 and F8 are competing over dominance for language.  F8 (the analogue to Broca’s Area at F7) is supposed to be like an understudy for the main character in a play.  It walks around back-stage, mouthing the words to Hamlet’s soliloquy while F7 is out on the stage […]

Substance Use/Abuse See also The Impact of Medication and Drugs on Neurofeedback Training I generally sit down with a new client who is admittedly–or appears possibly to be (on the assessment)–using drugs or alcohol and try to get him/her to specify what they get from using.  Also what they hope to achieve through training.  It […]

Tardive Dyskinesia I would expect, in any kind of movement control issue, that SMR would be an important place to look in your training plan. If you have a disconnect in the assessment, any you see it both in the amplitudes and in the percents, then that is a good place to test first. But […]

Tics Tics aren’t necessarily a physically-located thing, they are usually related to Filtering/Control problems–not necessarily to autonomic tone.   You pretty much train to get the brain able to produce better and longer bursts of SMR in the sensory-motor cortex.   I’ve never been clear on what the particular rationale for C4/P4 (or Pz) was. SMR […]

Tourette’s Tourette’s would actually usually be a combination of Filtering and Blocking:  ADHD with OCD features.  It is usually characterized by too MUCH dopamine, rather than too little.  Tourette’s often represents a very immature brain in terms of frequencies (tendency for many bands to be slower than you would expect for the chronological age), so […]

Tinnitus Tinnitus is one of those things that sometimes responds to NF, sometimes doesn’t. It is often related to high levels of sustained stress, so T3/T4 would be a reasonable starting place. Same as always with T3/T4: very low frequencies (2-5 Hz) down and starting with SMR as your augment and reducing the training frequency […]

Trauma I don’t worry too much about looking for trauma indicators, since I agree with Von der Kolk:   I don’t know that I’ve seen more than a few clients who wouldn’t qualify as having trauma experiences. If trauma is defined as a situation where the brain enters fight-or-flight mode but can’t run away and can’t fight–in […]

Vertigo Although there are anecdotal reports of effects on balance and gait from training below O1 and O2–about level with the inion, that’s all I’ve ever seen.  Theoretically, since the Cerebellum, which is the area you are speaking of, has no pyramidal cells, it should not produce an EEG signal, and thus feedback shouldn’t “catch […]

Vision Issues Fritz Perls among others asserted that many vision issues were related to brain states. An anxious person, for example doesn’t want to see very far, etc. He used to use Gestalt therapy to change people’s vision, and I’ve seen it happen a number of times over the years. I’ve worked with several clients […]
