MEMORY - A NEW PERSPECTIVE - Charan Ranganath PhD #68

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

PLANT INTELLIGENCE, MEMORY & COMMUNICATION - Monica Gagliano PHD #67

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.

MORPHIC RESONANCE, NATURE'S MEMORY & EXTENDED MIND - Rupert Sheldrake PHD #66

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? References: Rupert Sheldrake, “A New Science of life”.

POST-REDUCTIONIST SCIENCE - Marcelo Gleiser PHD #54

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”.

UPDATING OUR MENTAL HEALTH APPROACHES - Camilla Nord PHD #61

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.

THE PHYSICS OF RETRO-CAUSATION AND TIME SYMMETRY - Daniel Sheehan PHD #60

Can time symmetry in physics, combined with exceptional violations of the 2nd law of thermodynamics, and the “quantum handshake” transactional interpretation of Quantum mechanics, open up main stream physics to the possibility of retro-causation? Could it help to explain the many paradoxes left open in modern physics? and is there experimental evidence for it? Today we have the extraordinary possibility of retro-causation to get our heads around: the apparently impossible phenomenon of events in the present causing changes in the past, or future events having an effect in the present depending on how you want to look at it. Today we’ll be approaching this topic via the context of time symmetry in physics. As far back as 1947, French quantum physicist Olivier Costa de Beauregard, began to question the usual interpretation of time in quantum mechanics, intuiting that something was missing from the model for the many paradoxes in Quantum Mechanics to remain unexplained. And then, with others get on board over the years, in the 80’s, John G Kramer, agreed that the missing ingredient was found in time symmetry and he proposed a ‘quantum handshake’ between the waves passing forward and backward in time at the moment of collapse; in this Transactional Interpretation of quantum mechanics, Kramer claimed he had solved the paradoxes. My guest today has put together this research, a re-interpretation of the 2nd law of thermodynamics based on violations where Entropy exceptionally does not hold, and theorisation about quantum correlates to consciousness to create a new theory of retro-causation, which he thinks can be tested. He is Daniel Sheehan, Author and Professor of Physics at the University of San Diego, specialist in plasma physics, violations of the 2nd Law thermodynamics and Retro-causation. He is the founder the Quantum Retro-causation symposia that met at The University of San Diego. What we discuss: 00:00 Intro. 09:00 Time dilation: the twin paradox. 12:20 Time symmetry: reversible time functions in physics equations. 13:20 Violations of the 2nd Law, the Entropic arrow of time. 18:20 Wheeler’s bizarre altered double slit experiment. 23:15 Wheeler’s ‘Participatory Universe’. 26:00 The history of retro-causation research. 29:15 Bergmann and Lebowitz ‘Two-State Vector Formalism’ theory 1964 31:00 Kramer’s “Quantum Handshake” Transactional interpretation of QM. 35:30 Sheehan’s theory of retro-causation. 36:45 The assumption of quantum processes acting in the brain. 39:00 Issues with quantum consciousness hypotheses. 42:00 Macroscopic quantum systems. 50:00 Precognitive retro-causation experiments: Graff & Cyrus  51:45 Triple blind experiments - blind ‘even to the universe’. 55:00 Is the subject finding out what actually happened important to the result? 57:00 Emotional charge in the future, influencing the past. 59:00 Are some events in the future already fixed? 01:01:30 Global Consciousness aggregate effects in physical systems. 01:02:30 Time symmetry allows the transmission into the past of important. 01:05:00 Wider science reception of such a paradigm shifting ideas as retro-causation. 01:05:00 Getting over our Second law biology habits.
