The Basal Ganglia Are More Than a Motor Circuit: What Deep Nuclei Mean for Neurofeedback Practice
The basal ganglia do not work as a switch that is either on or off, so treatment does not flip a broken circuit back into place; it shifts the balance of a system in which both pathways stay active. That is also a fair description of what neurofeedback does across 20 or 40 sessions. Set client expectations accordingly, and describe gains as graded and dose-dependent rather than as a repair.

Does Breakfast Change Brainwaves? A Careful Look at the qEEG Evidence
Standardizing the eating state, recording what a client consumed and when, and interrogating high beta before training will immediately improve the quality of your data.

Ten Ideas Shaping Psychopharmacology
What changes when clinicians treat diagnosis as investigation, mechanisms as hypotheses, and medication as one part of a larger therapeutic system?

Continuous Glucose Monitoring (CGM): Biofeedback You Didn't Know You Needed
For healthcare providers, CGM promises a better conversation. CGM is most powerful as patterned feedback, not as a verdict on a patient or a meal.

Revolutionary Neuroscience Ideas
Neuroscience now describes a body built from overlapping networks, local control systems, secretory tissues, glia, immune cells, microbes, and organs that report upstream and sideways.

The Human Microbiome Network
The heart, brain, and gut form one network coordinated by the central autonomic network, so depression, heart disease, and gut disorders often rise and fall together as allostatic load.

"A New Type of Dementia—Called Seizures": When Temporal Lobe Epilepsy Hides Behind a Psychiatric Diagnosis
A missed diagnosis carries real costs, because clinicians may prescribe medications that worsen the very problem they are trying to treat.

Meeting Neurofeedback's Next-Generation Ethical Challenges

Motivational Interviewing (MI) Can Increase Treatment Engagement
For many clients and families, MI needs to be threaded through the entire clinical encounter: assessment, feedback, treatment planning, and the ongoing work of therapy itself.

Reading Your Brain: A Guide to How the EEG Works
From diagnosing epilepsy to powering brain-computer interfaces, the EEG has shaped more than a century of neuroscience and clinical medicine. The central questions are what we are actually measuring and how we make sense of the signal.

Resilience and Heart Rate Variability: How the Body Learns to Weather Repeated Stress
Executive Summary Two patients can face the same pressure and walk away in very different shapes, and a recent study from Mainz, Germany, helps explain part of that difference at the level of the heart. Rösner and colleagues (2026) tracked how the autonomic nervous system responds to the same laboratory stressor when it is repeated over several weeks, and then asked whether more resilient people exhibit a healthier physiological pattern over time. Their answer was encouraging

Where Does Consciousness Begin?
Training programs teach, rightly, that the outer brain layer drives language, planning, and voluntary reports. That does not settle where felt experience begins.

Neurofeedback Strengthens Executive Function in Children with ADHD
For many children with attention-deficit/hyperactivity disorder (ADHD), the central struggle is not simply paying attention but regulating thought and behavior.

The Willpower Myth
The idea that willpower is a finite mental fuel, burned up by each act of self-discipline and replenished by rest or sugar, is one of the most widely believed myths in psychology.

Continuous Glucose Monitoring: Biofeedback for Type 2 Diabetes Patients
Clients should not chase every glucose peak, but rather turn patterns into safe, psychologically informed decisions. Behavioral health clinicians have a particular contribution to make. They can help clients receive sensor data as feedback rather than surveillance, especially when shame, perfectionism, disordered eating, or diabetes distress are already in the room.

Cortisol Myths Debunked: What Healthcare Professionals Should Know
Cortisol is rhythmic, context-dependent, and clinically meaningful only when interpreted in light of timing, symptoms, medications, comorbidities, and validated testing. Cortisol supports arousal, blood pressure regulation, glucose availability, immune balance, and survival itself. The risk emerges when secretion is excessive, deficient, poorly timed, pharmacologically altered, or uncoupled from normal feedback.

Inflammation Links Biomarkers, Glucose Variability, and the Heart–Brain Axis
When the body experiences chronic low-grade inflammation, the effects extend far beyond localized tissues because inflammatory cytokines, meaning immune signaling proteins, instruct the brain and autonomic nervous system to shift their operational states. The result is widespread systemic distress that crosses traditional diagnostic boundaries.

The Heart-Brain-Gut Connection: How Three Axes Maintain Stability Through Change
The heart-brain axis and the gut-brain axis are not separate systems. They share the same nerve, immune mediators, and stress hormones. Their shared purpose is allostasis, meaning stability through change.
