How can neuroscience help us personalise mental health diagnoses and treatments? How are mental heath stats changing and why? How effective are life style changes as a prevention? What other new treatments are proving promising and effective? In this episode we’re going to get an update on all the recent research from neuroscience that’s studying mental health, and not just the issues and the treatments being used to deal with them, but also the importance of the brain itself in the perception of our mental health, and the lifestyle choices that can preventatively ward off the issues before they arise; things like nutrition, sleep, exercise, and social contact. We’ll be looking at the big one: depression and its connection to inflammation, and a wide range of buzz therapies including psychedelic therapy and cold water immersion. Today’s guest has just written a book for the public on this topic “The Balanced Brain: The science of mental health”, and her lab at MRC Cognition and Brain Sciences in Cambridge bridges the gap between the nuts and bolts of cognitive neuroscience and the more mind base of clinical psychology. She is neuroscientist and author Camilla Nord. In 2022, she was named a Rising Star by the US Association for Psychological Science, and received the Young Investigator Award from the European Society for Affective and Cognitive Science. Now it strikes me that if we can integrate new evidence from brain research into the clinical psychology field, we‘ve got a much better shot at treating ever rising numbers of mental health diagnoses and perhaps educating a good portion of the next generation enough to avoid these issues all together. It may be a pipe dream but we’ve got to try. What we discuss: 00:00 Intro 07:00 Our perception of pain. 11:00 Body changes lead to mental health changes. 12:00 Our ‘Inside-out’ perception is an active predictor of our mental health and the outside world. 16:00 The importance of narrative repetition to our self-perception. 18:00 Individualised data and solutions to mental health are impractical for our one-size-fits-all medical systems on a budget. 23:30 Nutritional Psychiatry - the connection between diet and mental health. 26:30 Gut-brain axis importance. 28:00 The risk of dieting affecting pleasure centres and thus motivation and mental health. 30:00 Inflammatory diet choices and lifestyle leading to depression. 33:30 Microbiome research: promise vs wishful thinking. 37:45 Social connection, nature connection and connection to meaning. 40:45 Some mental health symptoms can be useful and adaptive. 43:20 Sport and physical exercise to improve mental health. 46:00 Depression leads to a lack of drive to obtain pleasure - Anhedonia. 48:20 Sleep neuroscience. 53:30 Anger management and ‘hangriness’. 56:20 The Placebo effect is a useful part of a treatment’s effect. 58:00 Changing diagnosis rates in mental health. 01:02:00 Psychedelic therapy was unpopular before the last 10 years of study. 01:06:00 MDMA’s uses for PTSD, and modifying beliefs and expectations. 01:08:10 Connection between psychosis and cannabis. 01:09:20 Cannabis CBD Oil treatment of THC addiction. 01:11:15 Cold water immersion for euphoria and pain tolerance. 01:13:00 The changing nature of mental health.

More from Chasing Consciousness
Do EM fields across and around the body and brain correspond to and contain information about our experience of consciousness? Can resonance help explain how larger and smaller systems with consciousness can harmonise into a single field of consciousness? Does mind evolve as matter evolves? Today we have the possibility that consciousness relates to electromagnetic fields to look into. So, we get into the arguments for why consciousness might be baked into the physical world as panpsychism holds; we compare General Resonance Theory to other electromagnetic theories of consciousness; look at how GRT solves some of the problems of panpsychism like the combination problem and the boundary problem; and how we might use resonance to theorise about consciousness at various levels of existence above and below our single organism subjective experiences; we get into why the hippies were right about vibration, fields and resonance, and also what the hippies got wrong; And we also get into some of modern science that seems to show an alignment between science and spiritual ideas rather than an incompatibility. For this broad range of topics we are fortunate to have the polymath, environmental lawyer, author and philosopher at University of California Santa Barbara, Tamlyn Hunt. He’s written over 40 academic papers and 3 books for the general public, “Eco, Ego, Eros”, “Mind, World, God” ,and his brand new book “The Hippies Were Right”, which we focus on today.
How can we explain vivid, life changing experiences and true perceptions occurring in patients between brain death and resuscitation? What are the implications of true information being anomalously communicated during these experiences? What are the implications of some children being able to access the memories of deceased people? Why do such a high portion of these kids remember a traumatic death?
How have metrics surreptitiously replaced our internal value guidance system? How much nuance is lost when we scale collective counting across contexts? How dangerous is data that at first appears independent, whist in fact having heavy value assumptions baked in from that start? Today we have the worrying topic of value capture to discuss; that is the phenomena of how the majority of our personal values have been outsourced to external generic data sets and measurable scoring systems, often without us realising it. We discuss how, whilst useful in getting the wider picture, these measurables replace our internal lived sense of why things are important, motivating and worthy of goal directed behaviours. We also get into the root of this phenomena in the artificial demotion of the subjective to a lower level of value than the objective; how subjectivity is in fact supertangible and salient rather than intangible; and we get into how data is not neutral and has interests that in turn influence how we collect that data - risking a kind of objectivity laundering. On the other hand we also look at what measurables are good for, and how awareness of the tension between our external and internal value guidance, offers a middle road that gets the best of both worlds. Fortunately to unpack this slippery topic we have the philosopher of games and art at the University of Utah, C. Thi Nguyen. He’s the author of over 70 academic papers and 2 books for the general public. “Games: Agency as Art”, and his brand new book “The Score: How to stop playing somebody else’s game”, that we’ll be focussing on today.
Why were fungi so important to the evolution of life on earth? How do they collaborate with plants to help them communicate? What does the difficulty separating individual fungi from the collective of a mycelial network teach us about collective intelligence and interconnected co-dependence in ecosystems? In this episode we discuss how fungi are a brilliant example of symbiosis in nature. We get into their importance to evolution; how they facilitate plant communication; how they exhibit both collaboration and competition simultaneously; how they can solve problems without brains; and how they confound our ideas of ‘self’ and ‘other’. Fortunately to decode these ideas we have biologist, ecologist, mycologist and award winning author Merlin Sheldrake as our guide. He is a research associate at Oxford University and Vrije University in Amsterdam. He has written 20 scientific papers and his 2020 book “Entangled life - How Fungi make our worlds, change our minds, and shape our futures”, has sold more than a million copies in over 30 languages. The book received the 2021 Royal Society Science book award and the Wainwright prize for writing on Global Conservation. What we discuss: 00:00 Intro 05:00 Entangled Life Book. 06:40 The difference between the plant and fungal kingdoms. 08:00 Mycelium Networks: shapeshifting, sprawling networks. 09:55 Fungi’s symbiotic role in early evolution of land plants. 13:15 Mychorrhizal fungi: plant partners. 14:00 Katie Field - Re-creating early earth conditions in the lab. 15:50 Plant-Fungi electrical and chemical signalling. 19:40 Mutual vs parasitic simbiosis. 22:15 Inherent intelligence in fungi behaviour. 27:15 The skin and gut microbiome. 31:45 The enteric nervous system - possible mood changer. 33:00 The dance of competition and cooperation in evolution. 37:30 Climate Change innovations with fungi - Carbon cycling. 39:50 Writing Fungi into conservation targets with better data. 42:00 Fungal problem solving and distributed intelligence. 46:00 The blurring of self and other - fungi make us reconsider our separateness. 48:00 Individuality is a convenient concept but over emphasised. 50:00 The wood wide web over romanticised concept. 52:00 Fungal communication studies. 55:00 Sound communication in plants & fungi. 58:00 Implications of plant and mushroom memory.

How has new research changed the way we see nutritional health? What role do ultra-processed foods, fibre, gut microbes, inflammation and insulin resistance play in the new paradigm? Why does the gut microbiome affect our mental health? How can simply diversifying the quantity of plants in your diet change health outcomes radically? In this episode we have the complex topic of nutrition to get up to date on. There’s been so much research over the last 20 years that has contradicted some of our most deep seated preconceptions about food, so today we clarify science’s new take. We discuss the rise of lifestyle medicine as a solution to western health crises; individualised diet; ultra processed foods; fibre; glycemic index issues; the gut microbiome; inflammation; a variety of foods over restrictive diets; how to support the use of new GPL-1 weight loss drugs; and what the nutritional organisation Zoe is doing to make this all easier for the public to put into practice.
