The FitMind Podcast: Mental Fitness, Neuroscience & Psychology

Cognitive scientist Dr. Therese Huston joins The FitMind Podcast to share practical, research-backed ways to sharpen focus, lower stress, and keep the brain healthy at any age. Drawing from decades of neuroscience, she explains why multitasking quietly erodes attention and memory and what to do instead.
 
We explore simple, realistic habits that help your mind function at its best: 20-minute single-task blocks, 40 Hz binaural beats for deep focus, and a brief 5-2-7 breathing technique that can quickly calm the nervous system. Dr. Huston also highlights how aerobic movement, dance, and social connection drive neurogenesis and long-term brain vitality.
 
If you’ve ever felt scattered, stressed, or mentally drained, this episode offers grounded science and clear tools for regaining clarity and calm in daily life.

#105: Freediving & Mental Mastery - Will Trubridge

Can cells outside the brain learn, remember, and make decisions?
 
In this episode, neuroscientist Dr. Nikolay Kukushkin shares groundbreaking research that shows even non-neuronal cells can recognize patterns, count, and store information in ways strikingly similar to brain cells.
 
We explore:
 
 • 

Why memory may not be limited to the brain
 • 
 • 

What sea slugs can teach us about human cognition
 • 
 • 

How prediction and perception shape our sense of self
 • 
 • 

The parallels between AI and biological intelligence
 • 
 • 

Whether trauma could be “stored” in cells outside the nervous system
 • 
 
Dr. Kukushkin's work suggests we rethink intelligence, not as something exclusive to the brain, but as a fundamental property of life.

#104: Intelligence Beyond the Brain - Nikolay Kukushkin, PhD

Dr. Iain McGilchrist, a psychiatrist, philosopher, and author, joins the FitMind Podcast to explain how the brain’s two hemispheres shape our perception, attention, and consciousness. He explores how the left brain’s dominance in modern culture leads to a fragmented, analytical worldview, while the right hemisphere offers a more connected, meaningful experience of reality.
 
We discuss the moral and spiritual dimensions of attention, the limits of language, the nature of consciousness and the self, and how walking supports fluid thinking. McGilchrist also shares insights from his recent work with biologist Mike Levin on emergence and form.
 
This episode combines neuroscience, philosophy, and spirituality, inviting a shift toward a more balanced and integrated perspective on the world.

#101: Movement as Meditation - George Thompson

In this episode, neuroscientist and clinical researcher Dr. Justin Feinstein discusses the fascinating science and therapeutic potential of flotation therapy.
 
Often misunderstood and mislabeled as “sensory deprivation,” Dr. Feinstein explains why this is a misnomer and what’s truly happening inside the float tank. Instead of depriving the senses, floating creates an environment of deep physical and mental rest, allowing the nervous system to reset.
 
We explore Dr. Feinstein’s pioneering research on using float therapy to help individuals with PTSD and high anxiety sensitivity. He also shares insights into how flotation therapy could become a valuable tool in the public health system, especially for trauma survivors and people with severe anxiety.
 
Dr. Feinstein highlights compelling case studies, including patients with anorexia nervosa who experienced meaningful relief through floating, as well as its growing popularity among high-performing athletes looking to optimize recovery and mental performance.
 
Whether you’re new to flotation therapy or familiar with the practice, this conversation reveals its untapped potential and emerging role in both mental health and peak performance.

#100: Float Therapy: Science, Healing & Peak Performance - Justin Feinstein, PhD

This episode features Dr. Philippe Douyon, a board-certified neurologist specializing in neuroplasticity, brain health, and cognitive resilience.
 
We discuss the brain’s ability to adapt and reorganize, challenging misconceptions like the belief that cognitive change is limited to early life. 
 
Dr. Douyon explains how inherited mindsets shape thought patterns and how intentional habits can rewire the brain for better cognitive function.
 
Key strategies for brain health, including diet, fasting, exercise, and lifelong learning, are explored, along with neurodegenerative disorders and the effects of chronic stress.
 
Practical approaches to mental fitness and stress management highlight how individuals can enhance cognitive resilience and take control of their brain health.
