Speaker Bio:
During his PhD at University of London, Tomas used transcranial magnetic stimulation to probe for the plastic effects of neurofeedback, showing for the first time cortical excitability changes directly after a training session. During his postdoc at University of Western Ontario, he uncovered that alpha-desynchronizing neurofeedback leads to correlated reductions in mind-wandering. This led to the first translational study investigating this protocol's impact on patients with PTSD, revealing a positive effect on well-being and a plastic modulation of key brain networks. Currently at the University of Geneva, Tomas is investigating the impact of neurofeedback on neurological and psychiatric disorders within the framework of critical brain dynamics.

The Self-Tuning Brain: Normalizing Brain Oscillations with Neurofeedback
Webinar Abstract:
Using Hebbian as well as homeostatic models of brain plasticity, the effects of neurofeedback (NFB) are examined from the theoretical perspective of EEG normalization. Within this framework, hyper- and hypo-synchronous oscillations characteristic of abnormal brain dynamics are reversed with NFB training, as seen in several brain disorders including attention-deficit hyperactivity (ADHD) and post-traumatic stress disorder (PTSD). The central thesis put forward is that NFB re-tunes pathological oscillations toward intermediate levels of coupling, which may support self-organized criticality and provide an optimal balance between network flexibility/stability.

super interesting video so far! A question pops up around minute 28:30. What did originally lead you to apply reduction of alpha in PTSD? Isn't the applied selected protocol specific (or semi specific) to the type of state you are trying to correct?? If it turns out PTSD patients have reduced alpha what is it that made you select alpha reduction as a protocol to that group of individuals??
Good video 👍
What is EEG synchronization/Hurst on LSD?
is slower-wave alpha1 more central than alpha2? is alpha1 more pronounced in adult ADHD relative to others?
is ADHD reduced modularization? (more central coherence?)_
Advice to potential patients - DO.NOT.DO.THIS. This is a dangerous practice - the way the brain can be influenced and changed is still largely unknown. Despite all the pop science rhetoric, neuroscience is still largely in its absolute infancy. Take it from me - whatever problems you might be experiencing, messing with a bunch of idiots and crooks who don’t know what they’re doing and don’t care, just isn’t worth it.
You don’t know what you’re talking about
can you share your experience with nuerofeedback?
PhDs and MDs are involved in neurofeedback. It is absolutely NOT POP psychology.
