The FitMind Podcast: Mental Fitness, Neuroscience & Psychology

World champion freediver Will Trubridge explores the depths of the mind and ocean, sharing mental techniques honed through decades of extreme performance.

In this episode, he explains how breathwork, mindfulness, and what he calls the “mental immune system” can help us face fear, build resilience, and expand awareness.

Discover how lessons from the deep sea translate into a healthier, more conscious life on land.

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.

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.
