Chasing Consciousness

How much can a change in diet influence symptoms of mental health disorders? Why are a diversity of plants and whole foods so important to include, and ultra processed foods so important to remove? Why are inflammation and microbe diversity in the gut so key to this question? What does this research mean for the life-style medicine movement and to world food policy?In this episode we have the exploding new field of nutritional psychiatry to get to grips with, that is the way our diet can influence and even treat mental health conditions. We’re going to be discussing the historical separation of mind and body by science, which has led to scepticism that diet could influence mental health outcomes; the new understanding of the importance of diversity in our microbiome and inflammation to our mood and mental state; our main topic which is going to be the radical results of recent trials showing large changes in cognitive and mental health outcomes when diet is altered; we’ll get into the foods that can bring about that change and why they work; and we’re going to be getting into the reasons for the broken industrialised food environment that has contributed to the current mental health epidemic in the west.Fortunately, to understand this complex new field, our guest today is the very scientist that risked her reputation to conduct the first trials, facing considerable pushback, only to shift the consensus remarkably quickly with some top science, Felice Jacka. She is the Deakin University Distinguished Professor of Nutritional Psychiatry in Melbourne, the founder and director of the Food & Mood Centre, and of the International Society of Nutritional Psychiatry; She has been cited in over 100 institutional directives for food policy including the World Health Organization and UNICEF; and she is also the author of two books on this for the general public, the children’s book “There’s a Zoo in my Poo” and for adults “Brain Changer: How diet can save your mental health” which we’ll be covering today. Her impact has been so high on public health that in 2021 she was awarded the Order of Australia for her services to nutritional psychiatry.What we discuss:00:00 Intro08:50 The historic separation between mental and physical health. 10:35 People with mental health die about 20 years earlier. 13:30 The connection between the immune system and mental health. 16:20 New microbiome & chronic inflammation research’s influence on psychiatry. 20:00 Epigenetics, mitochondria (energy generation) & neurotransmitter influences. 21:15 Gut brain axis & oxidative stress response.33:30 The SMILES trial results and their integration into the consensus. 38:30 Using the Press to shorten the usual 20 year gap between results and policy change. 43:00 Industrialised food is the leading cause of chronic disease & biodiversity loss. 45:00 ‘We’re not going to tell people what to eat’: the food lobby’s ‘nanny state’ argument. 50:00 Soil depletion and the soil microbiome. 50:50 The life-style psychiatry movement: Diet, sleep and exercise. 01:05:30 Take out ultra-processed foods - even the nutritionally balanced ones. 01:12:30 Cognitive ability and memory reduced by processed foods. 01:14:45 Nutritional and energetic equivalent foods have totally different outcomes for the microbiome. 01:19:15 Put in a variety of plants - 30 a week. 01:20:20 The mediterranean diet. 01:24:50 Polyphenol science so far. 01:27:00 Emulsifiers and artificial sugars - the mucosal lining of the gut. 01:30:15 Fermented foods - the waste products of the bacteria are beneficial.

In this discussion, Evan Thompson, a Professor of Philosophy at the University of British Columbia and a noted scholar in cognitive science and Asian philosophy, dives into the synergy between cognition and the body. He explores the concept of autopoiesis and its implications for understanding consciousness. The conversation delves into the crossover between Buddhist philosophy and cognitive science, advocating for a holistic view that transcends objective and subjective divides. Thompson also critiques the commercialization of meditation while emphasizing the importance of community in mental well-being.

Why and how do we store certain memories and not others? What lifestyle elements influence memory for better or worse? Can traumatic memories be reframed and lead to reduction in symptoms?In this episode we get into the most recent research into memory. So, how we store memory; the different types; the way we actively construct it rather than simply receiving it; it’s importance to our sense of self and framing of the world; to our attention and motivation; to our openness and updating our beliefs; and to Deja Vu. We talk about the influence of screen time and multi-tasking on memory; some unexpected life style factors that influence the quality of memory function and how they can feed into memory disorders; and we discuss traumatic memories and how we can reframe them, and the psychedelic research on that too.Fortunately, our guest is one of the world’s most fun and knowledgeable authorities on memory, psychologist, neuroscientist, and head of the dynamic memory lab at The University of California Davis, Dr. Charan Ranganath. He’s the author of over 120 scientific papers on memory and has recently released a fascinating book for the general public on all this, “Why We Remember”. Charan is also a rock guitarist with several bands so a man of many talents. What we discuss:00:00 intro. 07:20 The remembering self vs experiencing self. 09:30 We forget a lot, we’re supposed to.11:00 Autobiographic memory.13:30 Episodic memory.14:20 Emotional intensity brings attention, which is linked to motivation.18:20 Association, cue and prompts, and the hippocampus.20:30 Memory athletes and training memory.21:51 Storifcation, mental schemas and ‘scaffolding’ new memories with old blueprints.24:40 Preconceptions, bias and prejudice is baked into new memories.27:00 Imagining the past (re-membering) and imagining the future are very similar in the brain.29:15 The brain is not linear, rather a global network of dynamic interaction between brain regions simultaneously.31:29 Prediction error, goals, and memory enhancement.37:00 Dopamine drives our attention, interest and curiosity, multiplying remembering.43:20 Mental flexibility, youthful neuroplasticity, and openness to new experience.46::00 The ‘Stage of Life’ theory of memory.49:00 The young brain needs to struggle to get the information they’re curious about.50:15 Deja Vu research and familiarity.54:20 The environmental and social components of memory. 58:15 The act of remembering can change that memory.01:00:00 Collective memory - shared memories support sense of self.01:01:20 Life style factors: good for the body = good for the brain, so good for memory.01:02:00 The importance of vascular health and inflammation.01:06:30 Depression inversely correlates with memory.01:08:45 Screen time, focus and memory.01:10:20 Multi taking is actually switching, and leads to fragmented memories.01:12:30 Traumatic memories and reframing them.01:19:20 Psychedelic reframing of memories. 01:20:20 Extinction learning - learning to suppress memory prompts and re-write them.References:Charan Ranganth, “Why We Remember” Daniel Kahneman, “Thinking Fast and Slow”Hermann Ebbinghaus, “Memory: A Contribution to Experimental Psychology” 1885Endel Tulving, ‘Mental time travel’Frederic Bartlett, 1930 ‘Imagining the past and constructing the future’Mathias Gruber and Charan Ranganath, “How Curiosity Enhances Hippocampus-Dependent Memory: The Prediction, Appraisal, Curiosity, and Exploration (PACE) Framework” PaperAnne Cleary, Deja Vu experiments article

How do plants communicate using sound? How do they remember previous stimuli that have proven not to be threat, when at first they seemed like one? Where is the memory encoded considering they have no brain? What are the implications for biology of plant memory? In this episode we cover the ground breaking topics in plant cognition studies of: plant intelligence, behaviour, memory and communication. The type of experiments presented here have never really been done before, because there has always been an assumption in plant science that the cellular cognition that all living cells have, relies solely on light, touch or chemical interactions; so it doesn’t really permit for plant behaviour, memory and consciousness. So with my guest today, the first scientist to bypass the assumptions and try these tests, we’re going to discuss her experiments with plants; that clearly show not only basic memory and the corresponding updated behaviour based on that memory, but even pavlovian memory, i.e. associative memory that requires arbitrary stimuli to take on meaning to the plant. Obviously all of this has massive implications for distributed memory and memory beyond brains. We’re also going to get into plant medicine and other indigenous approaches to connecting with plant consciousness; and what plant communication and biophilia in general might do for our relationship to the natural world as we face imminent biosphere collapse. My guest is of course, the research associate professor of Evolutionary Ecology at several universities in Australia, Monica Gagliano. She’s published over 60 scientific papers, across the fields of Ecology, Plant Cognition, Plant Communications and Marine Ecology. She is also the author of the books “The Language of Plants: Science, Philosophy and Literature”,  and the highly celebrated,“Thus Spoke the Plant, A remarkable Journey of Groundbreaking Scientific Discoveries and Personal Encounters”. What we discuss: 00:00  Intro 05:00 The consensus on Plant intelligence & communication. 09:20 The difference between reacting and responding in cognition. 10:00 Bio-acoustic communication between plants. 21:07 Possible methods for plants to percieve sound. 22:00 Response to gravity may be similar. 23:30 Her plant memory experiment with Mimosa. 27:15 ‘Habituation’ learning: screening out non-useful stimuli. 32:15 The connection between hardship and accelerated adaptive learning. 37:50 Her ‘Pavlovian’ associative memory experiment with peas. 46:10 The Implications of plant memory for modern biology.  49:25 Where is memory stored without a nervous system? 52:30 Monica’s ethical crisis in animal studies. 01:00:00 ‘Pavlovian’ associative memory experiment with peas. 01:01:30 ‘Dieta’, amazonian plant communication practice. 01:05:00 Shamanic interface with plant wisdom, particularly for healing. 01:08:00 Reductionist materialist pushback is representative of the colonial history of abuse of nature. 01:11:00 Indigenous science and a new book in the making.

Where is nature’s memory of its evolution encoded? Is there evidence for extended mind occurring beyond individual brains? How possible is it that the sun is conscious? In this episode we’re going to get up to date on Rupert Sheldrake’s extraordinary theory of Morphic resonance: so Morphic fields, the unfolding of nature’s ‘habits’ and the ‘memory of nature’. We’ll examine the possibility of levels of consciousness larger than our own brains - scaling up in a hierarchy from cellular consciousness right up to planetary and perhaps even stellar consciousness! We’re also going to get into examples of consciousness beyond the brain like ‘the sensation of being stared at’ (clearly a useful skill to evolve) and other phenomena Rupert has reported in his experiments.  Rupert Sheldrake is a Cambridge PHD developmental Biologist whose published over 100 papers on topics as wide as Cellular Biology, telepathy, Pets who know when their owners are coming home, and after-death communications. He is also the author of many books like “A new science of life”, “Science set free”, and “Ways of going Beyond”, among many others. What were discuss: 00:00 Intro. 06:10 Morphic resonance explained. 08:15 Polar Auxin - death in the midst of life. 09:15 Genes make proteins, morphogenetic fields determine form. 11:30 Nature’s “memory” spread across time. 13:25 Something that has happened before is more likely to happen again. 14:15 Collective memory, like Jung’s collective unconscious. 17:15 His scientific education engrained materialism and atheism in him.. 18:15 Asian philosophy, psychedelics, Neo-platonism and Christianity. 20:30 Questioning of scientific dogma came before his faith. 22:00 Thomas Kuhn’s paradigm change, an analogy for him breaking with science. 23:50 Rupert’s work denounced as ‘Heresy’ by the editor of Nature in 1981.  26:30 Measuring Morphic fields in experiments. 28:30 IQ tests have got easier for people over time, The Flynn Effect 30:00 Video games have to make new versions harder each time.  32:10 Is subtle energy field research beyond science? 37:00 Bioelectric morphogenetic fields & Michael Levin.  41:20 Bioelectric fields are the interface not the explanation. 42:30 Where are morphic fields recorded in nature? 44:50 Platonism doesn’t explain evolution and change over time. 47:00 Different levels of collective consciousness, up to planetary, stellar and even cosmic consciousness. 56:40 The feeling of being stared at: examples of extended mind. 01:02:55 Mystical experience - being part of a greater consciousness. 01:09:40 Are spiritual & scientific insight compatible?

Why is our subjective experiences and cultural context inseparable from our scientific theories and attempts to be objective? Why is it that the more we know, the more we know we don’t know? What does reductionist materialism miss out from the scientific picture and what does a post-reductionist science look like? How can understanding some of materialism’s incompleteness help us face humanity's greatest problems? In this episode we have the blind spots of enlightenment science to assess; we’re going to be investigating the common belief that science can provide a universal, objective, God-like perspective of the truth of things, independent from our human experience. We’re also going to look at the implications of the consensus in science that all phenomena can be reduced to solely material causes, and what that may be missing out. To assess this we’re going to be looking at data from cosmology, biology, cognitive science and quantum physics and thinking about the assumptions that are so baked in to our western scientific approaches, that we may have forgotten they’re assumptions at all.  In order to do this we’re going to be speaking to Brazilian professor of theoretical physics at Dartmouth College, Marcelo Gleiser. Marcelo works on a range of topics from Cosmology and information theory, to the history and philosophy of science, and how science and culture interact. He’s also the author of many popular science books including most recently, “the Dawn of Mindful Universe: A manifesto for humanities future” and his new 2024 book which we’ll be focusing on today, “The Blind Spot: Why Science Cannot Ignore Human Experience”, Co-authored with astronomer Adam Frank and philosopher Evan Thompson, who will be not he show in the next series. Gleiser’s also the first South American recipient of the prestigious Templeton Science prize for his standpoint that science, philosophy and spirituality are complementary expressions of humanities deep need to explore the unknown. I have wanted to speak to Marcelo about the limits of science and a post-reductionist approach to science since he was recommended by my previous guest psychiatrist and brain-hemisphere researcher Dr. Iain McGilchrist in the series one episode “Navigating beyond Materialism”, and I’m extremely glad I followed him up on it. What we discuss: 00:00 Intro 06:14 Asymmetry is also beautiful.  11:40 The more you know, the more you know you don’t know. 18:00 ‘Interbeing’ - buddhism and the philosophy of science. 22:00 Bacteria are our ancestors. 23:00 Sacred ancestral knowledge - belonging & gratitude for nature. 30:00 Extremely unlikely chemical steps and extinction events required for life to develop. 35:00 The chances of intelligent technological life on other planets. 37:00 Fine-tuned for life VS the anthropic principle. 50:30 Post-enlightenment sacredness. 52:00 The rise of reductionism.  01:03:30 Newton was troubled by his theory. 01:08:37 Strongly and weakly emergent phenomena. 01:12:00 Downward or upward causation? Dualism or monism? 01:17:50 Scientific concepts are stories, and stories are simplifications too. 01:21:20 “The Blind Spot: Why science cannot ignore human experience”. 01:26:31 “Sureptitious substitution” of concepts for experiences. 01:28:45 Is consciousness fundamental? 01:42:45 Blindspots in the hard sciences - jumps that are too big. 01:53:30 Marcelo’’s new “The Island of Knowledge’ centre in Tuscany. Quote: “Gravity must be caused by an agent, acting constantly according to certain laws; but whether this agent be material or immaterial, I have left to the consideration of my readers.” — Sir Isaac Newton (Third letter to Bentley, 25 Feb 1693) References: Marcelo Gleiser, “The Blind Spot: How science must take include human experience”.
