Dr. O'Leary provides a critical analysis of increasingly popular claims that modern neuroscience confirms the teaching of Buddhist philosophy, and questions whether many of these claims are even consistent with Buddhist teaching.  He also explores whether the increasing number of claims that mindfulness meditation has strong neuroscientific backing and clear neuroanatomical correlates are supported by the evidence.

Why do conversations so rarely begin with the phrase, "We need to undefine our terms"? In this episode of PsyDactic, host Dr. T. Ryan O'Leary challenges us to do exactly that with one of the most elusive concepts in science, psychology, and neuroscience: consciousness. To truly understand what it means to be conscious, we first have to let go of what we are sure it is.

Dr. O'Leary discusses his critical perspective on Oppositional Defiant Disorder (ODD) and argues that ODD is not a primary diagnosis but rather a risk syndrome, a set of symptoms (defiance, irritability, and vindictiveness) resulting from various underlying conditions like ADHD, anxiety, or trauma. He explains that conceptualizing ODD as a stand-alone disorder often leads to the risky treatment pathway of off-label antipsychotic medication, whereas recognizing it as a syndrome necessitates an etiology-focused approach to treat the true root cause, typically with safer, condition-specific interventions. Dr. O'Leary traces the evolution of ODD criteria through the DSM manuals and urges clinicians to use comprehensive evaluations rather than relying on simple screeners, especially when an ODD diagnosis is present.

Neuroplasticity is a real thing that is shrouded in mythology and used by companies to market products, but what do we actually know about neuroplasticity?

Dr. Grant Brenner joins Dr. O'Leary to explore the fascinating intersection of human psychology, physics, psychotherapy and artificial intelligence.  We discuss Active Inference and The Free Energy Principle along side how babies develop a sense of self and so much more.

Is it possible to house multiple alternate selves within the same brain?  Dr. O'Leary argues that it is not only possible, but under certain conditions it is likely to happen.  Dissociative Identity Disorder is discussed not as a "shattering of the self,"  but instead as a failure to integrate the self during development.  Dr. O'Leary explores different biologically and computationally plausible models to explain how the self might fail to integrate during the normal process children go through in order to distinguish the self from others and others from others, as they build a (usually) coherent model of themselves.

Dr. O'Leary explores the neuroscience of dissociation, defining it as a degenerate concept that refers to a wide range of functional disconnections within the brain rather than a single clinical entity. The discussion moves from the standard medical definitions—such as depersonalization, derealization, and amnesia—toward a broader view of dissociation as a neurobiological defense mechanism that uses sensory attenuation to manage background noise and overwhelming trauma. By examining how specific regions like the temporal parietal junction and the default mode network integrate our sense of self and environment, Dr. O'Leary compares how disruptions in these areas lead to the fragmented reality experienced in various psychiatric conditions. This discussion aims to shift the listener's perspective of dissociation from a vague symptom to a complex breakdown of mental integration that can be induced by drugs, trauma, or even intentional meditative practices.

In December 2025, the FDA authorized  the Flow F100, an innovative at-home wearable headset that utilizes transcranial direct current stimulation (tDCS) to treat major depressive disorder. Unlike traditional pharmaceuticals that act systemically, this device targets the dorsolateral prefrontal cortex with localized electricity to modulate neuronal excitability and address the asymmetry hypothesis of depression. While the Empower study that evaluated this technology demonstrated statistically significant improvements in response and remission rates, the FDA approved it with a moderate level of uncertainty regarding its true efficacy due to a clinically insignificant 2.3-point difference on the average improvement using the Hamilton scale and potential unblinding bias in the trial. By contrasting frequentist and Bayesian statistical frameworks, Dr. O'Leary encourages a skeptical but curious evaluation of whether this technology represents a genuine clinical breakthrough or a temporary trend in the long history of electrotherapy.

PsyDactic welcomes The Game Theorist's Guide to Parenting co-author, Kevin Zollman who discusses game theory as the science of strategic thinking. We explore how mathematical models like the Prisoner’s Dilemma and mechanism design can be used to manage family dynamics by creating win-win solutions rather than competitive, zero-sum outcomes. The conversation highlights practical techniques such as "I cut, you pick" for fairness, the importance of making credible threats that parents are actually willing to execute, and ways to make honesty more profitable than lying through strategic questioning. While children may be impulsive and at times difficult to predict, applying game theory helps parents influence behavior by understanding their children's incentives and fostering a predictable environment built on reciprocity and trust.
