Increase Your Clients' HRV Measurement Accuracy
HRV is exquisitely sensitive to how, when, and under what conditions you measure it. Get the protocol wrong, and you will be chasing noise rather than signal.

Smarter Diagnosis, Fewer Surprises: An Introduction to Bayesian Reasoning in Clinical Assessment
Your confidence in a conclusion should update as new evidence arrives, and the size of that update depends on how informative the evidence is.

Parkinson's Disease as a SCAN Disorder
The central discovery is that M1 is not simply a mosaic of body-part territories. Woven among those effector-specific zones (the patches that control the hand, the foot, the mouth) lies a second system called the somato-cognitive action network, or SCAN.

Inter-Organ Communication: A Paradigm Shift
Scientists are now discovering that organs engage in a rich, multidirectional web of “crosstalk” that extends far beyond what nerves and hormones alone can account for.

Spotlight on György Buzsáki: What Brain Rhythms Mean for Neurofeedback
György Buzsáki argued, with decades of evidence behind him, that brain rhythms are not passive reflections of "brain states" but functional organizing tools that help the brain coordinate large populations of neurons in time.

John S. Anderson on Brain Flexibility, Resilience, and Choice as Goals for Neurofeedback
Neurofeedback training develops flexibility, resilience, and choice—skills that enhance any endeavor without altering personality or eliminating existing strengths.

Learning to Learn: How Better Reinforcement Design Makes Neurofeedback and Biofeedback Work (and Stick)
Neurofeedback outcomes improve when we stop treating feedback as “information” and start treating it as an engineered learning environment.

Listening to the Body: Why Interoception Might Be Critical to Mental Health
Interoception invites clinicians to ask not only "what are you thinking?" and "what are you feeling emotionally?" but also "what is your body telling you, and how clearly can you hear it?"
