We've Created Handouts for Your Clients

We have created client handouts for biofeedback, HRV biofeedback, neurofeedback, and chronic pain management based on AAPB's Evidence-Based Practice in Biofeedback and Neurofeedback (4th ed.). We distilled key concepts from AAPB and ISNR resources. You can find our client handouts under the Resources section of our website. Please use them in your practice.

We regularly update our most accessed resources, such as Brodmann Areas. This Spring and Summer, expect new Network and Drug Effects on the EEG guides.

Mentor Has a New Look and Expanded Knowledge

We've given Mentor GPT a new profile picture and updated its training documents.

We train and test Mentor for several hours each week. The training process involves selecting seminal research articles, preprocessing them so that Mentor can readily search them, and testing Mentor to ensure that it uses them when responding to queries. BioSource provides my Truman State University students with a Mentor link to tutor them on topics ranging from Physiological Psychology and Psychopharmacology to Research Design. We've trained Mentor on my latest full-length lectures in these courses.

We invite you to recommend peer-reviewed articles that you consider must-reads.

BioSource Tutorials

We update our tutorials during the Winter and Summer Breaks. We add cutting-edge content, prose, and graphics to enhance your understanding of the field. We carefully use multiple AI resources to generate textbook-quality content, including ChatGPT, Claude, Consensus, the Gamma App, Gemini, NaturalReader, Perplexity, Pxlr, and Superhuman (formerly Grammarly). Since the small details matter, we added precise EMG active electrode placement pictures to Biofeedback Tutor. Thanks to Truman alumnus Dr. Max McDermott for modeling.

We Rededicated Our Tutorials to Our Heroes

We have dedicated HRV Biofeedback Tutor to Drs. Paul Lehrer and Richard Gevirtz.

We have expanded our summary of Jay Gunkelman's incomparable and indispensable contributions to neurofeedback.

Finally, we have dedicated Neurofeedback Tutor to Michael and Lynda Thompson.

We're Planning Exciting Posts

We are slowing the cadence of our posts to one a week to give our staff and readers a breather. Upcoming posts will explore slow-paced contraction using data-acquisition systems, Stephen Porges' and Patrick Steffen's inspiring HRV Journeys, and best practices in the clinical assessment of ADHD and autism.

Check Out our Growing Galleries

BioSource now creates its watercolor portraits in-house. We recently recreated over 160 portraits and added narration. These are among our latest additions. We encourage your recommendations. Please click each portrait to hear a description of their contributions to the field.
