What if understanding the brain requires looking beyond symptoms and diagnostic labels to the electrical patterns that reveal how it actually functions?

In this episode of Brain Signals, David Ims sits down with Jay Gunkelman, one of the most experienced and influential voices in EEG and neurofeedback. With a career spanning more than five decades, Jay shares the unconventional path that led him into applied psychophysiology, from building early EEG equipment and working with patients in a state hospital to helping advance quantitative EEG (QEEG) and neurofeedback around the world.

Jay explains why he believes brain-based measurements can offer a more individualized understanding of the mind than diagnostic categories alone. He explores the concept of endophenotypes, the relationship between brainwave patterns and behavior, and how EEG-informed approaches may help clinicians make more personalized decisions about treatment.

The conversation also reveals the curiosity and creativity behind Jay’s work. He reflects on the clinical experiences that kept him committed to the field, the importance of recognizing patterns across thousands of EEGs, and why collaboration is essential when studying something as complex as the human brain.

Whether you're a clinician, neurofeedback practitioner, or simply curious about how the brain works, this conversation offers a fascinating look at the history, possibilities, and ongoing questions of neuroregulation.

In this episode, you'll hear about:

• How Jay Gunkelman found his way into EEG, biofeedback, and neurofeedback in the early 1970s
• The early challenges of developing EEG technology and building a new field of practice
• What endophenotypes are and how they may connect genetics, brain activity, and behavior
• Why Jay questions the limitations of relying on diagnostic labels alone
• How EEG and QEEG can inform more individualized approaches to neurofeedback and treatment
• The importance of pattern recognition, clinical experience, and ongoing scientific inquiry
• How brainwave activity relates to attention, intention, perception, memory, and arousal
• What decades of clinical experience have taught Jay about the complexity of the brain
• Why curiosity, collaboration, and mentorship continue to move the field forward

A central takeaway: The brain is extraordinarily complex, and no single person or diagnostic framework can capture all of it. By combining careful measurement, clinical insight, and collaboration, practitioners can continue exploring more individualized ways to understand brain function and support human well-being.

What if a mental health diagnosis tells you something important about a person—but not nearly enough?

In this episode of Brain Signals, David speaks with licensed mental health clinician, author, and neurotechnology specialist Penijean Gracefire about neuroregulation, brain mapping, and neurofeedback.

Penijean challenges the idea that the goal of mental health care should simply be to get people to conform to the expectations of the systems around them. She explores how easily we can move from asking “What is wrong with you?” to asking a much more useful question: “How does your brain work, what have you experienced, and what would you like to be able to do differently?”

Together, David and Penijean discuss:

• Why diagnoses such as ADHD or complex PTSD can provide useful information while still telling us very little about the whole person
• The limitations of trying to fit diverse human experiences into diagnostic categories
• How school, work, and other systems can unintentionally define differences as deficits
• Why being unable to function within a particular environment doesn't necessarily mean something is “wrong” with you
• The importance of understanding individual strengths as well as challenges
• How brain mapping can provide another piece of information alongside a person's history, symptoms, and lived experience
• We need mind, body, and brain to understand the whole person
• The role of neuroplasticity and the possibility of changing patterns in the nervous system
• The difference between helping someone function better and simply making them conform
• Why curiosity—and a willingness to question established frameworks—can lead to better care

One of the central ideas of this conversation is beautifully simple: there are many valid ways for a human brain to develop and interact with the world. The question isn't necessarily whether someone fits the expected mold. The question is whether they are able to build a life that meets their needs for connection, safety, significance, and meaning.

And sometimes, understanding the person requires looking beyond the box.
