New Books in Neuroscience

Ecological psychology holds that perception and action are best explained in terms of dynamic interactions between brain, body, and environment, not in classical cognitivist terms of the manipulation of representations in the head. This anti-representationalist stance, argues Luis Favela, makes ecological psychology deeply at odds with dominant trends in some parts of neuroscience. In The Ecological Brain: Unifying the Sciences of Brain, Body, and Environment (Routledge, 2024), Favela lays out the seemingly irreconciliable theoretical commitments of ecological psychology and neuroscience, and then defends a framework for reconciling them: the NeuroEcological Nexus Theory (NExT). According to Favela, who is an associate professor of philosophy and cognitive sciences at the University of Central Florida, complexity science provides the conceptual tools that can help integrate these frameworks, such as by articulating the key notion of affordances in ecological psychology as a kind of dimensional reduction in complexity science.

If you're interested in memory, you'll find a lot in Memory Makes the Brain: The Biological Machinery That Uses Experiences To Shape Individual Brains (World Scientific, 2021), from cellular processes to unique and interesting perspectives on autism. Detailed descriptions of cellular processes involved in forming a memory. Connecting those cellular processes to everyday experiences - like the memorable image of a butterfly seen during a hike decades ago. Comparisons of plasticity in different brain areas, like cortex, hippocampus, cerebellum. Comparisons of plasticity and learning in different phases of the human life. Important milestones in the history of neuroscience. Like Wiesel and Hubel's work identifying the critical period for plasticity, or Huttenlocher's discovery of synaptic pruning. Up-to-date science and open questions about autism, a wide range of phenomena that seems to be connected both to synaptic pruning and to the funtion of the cerebellum. An outlook on non-synaptic plasticity. Professor Christian Hansel starts both the book and the conversation with establishing a very broad definition of memory. Traditionally, a lot of research focused on the "observable outcome" of learning: acquiring new skills, changing behavior. Instead, he defines memory as any event that changes the brain.The first 2 chapters introduce major discoveries from the 1960s and 1970s. David Hubel and Thorsten Wiesel examined the visual system of kittens. They recognized that it's much more adaptive in a "critical period", ca. 4-8 weeks after birth. Peter Huttenlocher discovered another fascinating phenomena during childhood: synaptic pruning. In the years 2-12, a lot of synapses (connections between neurons) disappear.Chapter 3 describes the molecular machinery behind all these observations. We'll get to know the terms LTP (long-term potentiation) and LTD (long-term depression), which mean the long-term strengthening and weakening of synaptic connections respectively. We find a detailed description of these processes, incl. the enzymes, neurotransmitters and receptors contributing to them.Chapter 4 continues examining these processes across the human life span. The (perhaps surprising) conclusion: The machinery for synaptic plasticity is quite similar in a small child an in an adult. What's different is the magnitude of these processes.Autism is a central topic both in the book and in the Hansel Lab's work. Chapter 5 starts with describing the difficulties of a definition. ASD (autism spectrum disorder) is an umbrella term encompassing several symptoms and intensities. In the last years, it has turned out that low degree of synaptic pruning plays a significant role in multiple forms of autism. We'll see in the next years how the research about synaptic pruning and learning can be used for clinical purposes. Understanding the biological mechanism can also make it easier to relate to some peculiar-sounding symptoms. If we consider that an individual's brain contains an unusually high number of synapses, their reports about unusually intense perceptions suddenly become more understandable.A thought-provoking chapter is number 6. It describes various experiments with mouse models to study autism-like symptoms. The chapter might also make you reflect about the merits and shortcomings of animal models generally.The cerebellum was long considered to be the brain area for finetuning movements. Now, it's clear that its repertoire is much bigger. In the interview, Christian describes a hypothesis that the cerebellum has a capability of timing. This in turn makes it a crucial factor in several behaviors beyond sophisticated movements, including speech.We know a lot about synaptic plasticity and its significance in learning. Chapter 8 tackles the big, open question, what else? Which other processes contribute to memory formation? It presents some hypotheses about intrinsic plasticity. Learn more about your ad choices.

A new understanding of memory is emerging from the latest scientific research. In Why We Remember: Unlocking Memory's Power to Hold on to What Matters (Doubleday, 2024), pioneering neuroscientist and psychologist Charan Ranganath radically reframes the way we think about the everyday act of remembering. Combining accessible language with cutting-edge research, he reveals the surprising ways our brains record the past and how we use that information to understand who we are in the present, and to imagine and plan for the future.Memory, Dr. Ranganath shows, is a highly transformative force that shapes how we experience the world in often invisible and sometimes destructive ways. Knowing this can help us with daily remembering tasks, like finding our keys, and with the challenge of memory loss as we age. What's more, when we work with the brain's ability to learn and reinterpret past events, we can heal trauma, shed our biases, learn faster, and grow in self-awareness.Including fascinating studies and examples from pop culture, and drawing on Ranganath's life as a scientist, father, and child of immigrants, Why We Remember is a captivating read that unveils the hidden role memory plays throughout our lives. When we understand its power-- and its quirks--we can cut through the clutter and remember the things we want to remember. We can make freer choices and plan a happier future.

In this episode of the CEU Press Podcast, host Andrea Talabér (CEU Press/CEU Review of Books) sat down with Matt Qvortrup (Coventry University) to discuss his new book with CEU Press entitled, The Political Brain: The Emergence of Neuropolitics (CEU Press, 2024).Putting the “science” back into political science, The Political Brain shows how fMRI-scans can identify differences between liberals and conservatives, can predict our behaviour, and can explain the biology of uprisings, revolutions, and wars. The book also provides an overview of the state-of-the-art knowledge of the organ that shapes our politics. It warns that if we rely on the evolutionarily primitive parts of the midbrain, those engaged when we succumb to polarised politics, we stand in danger of squandering the gains we made through the last eight million years.Matt’s book is part of our new series, CEU Press Perspectives. The series offers the latest viewpoints on both new and perennial issues, these books address a wide range of topics of critical importance today. The new series, originating from an international collection of leading authors, encourages us to look at issues from a different viewpoint, to think outside the box, and to stimulate debate.You can learn more about the series here.The CEU Press Podcast delves into various aspects of the publishing process: from crafting a book proposal, finding a publisher, responding to peer review feedback on the manuscript, to the subsequent distribution, promotion and marketing of academic books. We will also talk to series editors and authors, who will share their experiences of getting published and talk about their series or books.Interested in CEU Press’s publications?

Why do we sleep? How can we improve our sleep?A century ago, sleep was considered a state of nothingness—even a primitive habit that we could learn to overcome. Then, an immigrant scientist and his assistant spent a month in the depths of a Kentucky cave, making nationwide headlines and thrusting sleep science to the forefront of our consciousness.In the 1920s, Nathaniel Kleitman founded the world’s first dedicated sleep lab at the University of Chicago, where he subjected research participants (including himself) to a dizzying array of tests and tortures. But the tipping point came in 1938, when his cave experiment awakened the general public to the unknown—and vital—world of sleep. Kleitman went on to mentor the talented but troubled Eugene Aserinsky, whose discovery of REM sleep revealed the astonishing activity of the dreaming brain, and William Dement, a jazz-bass playing revolutionary who became known as the father of sleep medicine. Dement, in turn, mentored the brilliant maverick Mary Carskadon, who uncovered an epidemic of sleep deprivation among teenagers, and launched a global movement to fight it.In Mapping the Darkness: The Visionary Scientists Who Unlocked the Mysteries of Sleep (Hachette Books, 2023), award-winning Kenneth Miller weaves together science and history to tell the story of four outsider scientists who took sleep science from fringe discipline to mainstream obsession through spectacular experiments, technological innovation, and single-minded commitment.Mapping the Darkness was named the Best Book of the Year 2023 by the New Yorker.

C. S. Sherrington said “All the brain can do is to move things". The Brain in Motion: From Microcircuits to Global Brain Function (MIT Press, 2023) shows how much the brain can do "just" by moving things. It gives an amazing overview of the large variety of motor behaviors and the cellular basis of them. It reveals how motor circuits provide the underlying mechanism not just for walking or jumping, but also for breath or chewing.The book emphasizes the evolutionary perspective. It demonstrates how the basic structures are the same across all vertebrates, suggesting that these systems have been around for more than 500 million years.At the very beginning, Grillner introduces the analogy of an orchestra: The microcircuits are the musicians, and the forebrain acts as the conductor. In the following chapters, the readers get to know all the important actors and their contribution to this "performance": the CPGs and motor centers that execute the movements, the tectum that synthesizes input from the direct surroundings of the animal, the basal ganglia and the cortex that together direct the microcircuits, and the cerebellum, which plays a crucial role in adapting the movements according to the environment and learning new motor behavior. The Brain in Motion provides both a great overview of the motor system and a detailed presentation of its major contributors. Learn more about your ad choices.

Today’s book is: Look Again: The Power of Noticing What Was Always There (Atria/One Signal Publishers, 2024), by Tali Sharot and Cass R. Sunstein, a book that asks why stimulating jobs and breathtaking works of art lose their sparkle after a while. People stop noticing what is most wonderful in their own lives. They also stop noticing what is terrible, due to something called habituation. Because of habituation, people get used to dirty air, become unconcerned by their own misconduct, and become more liable to believe misinformation. But what if you could dishabituate? Could you find a way to see everything anew? What if you could regain sensitivity, not only to the great things in your life, but also to the terrible things you stopped noticing and so don’t try to change? In Look Again, neuroscience professor Tali Sharot and Harvard law professor Cass R. Sunstein investigate why we stop noticing both the great and not-so-great things around us and how to “dishabituate.” This groundbreaking work, based on decades of research in the psychological and biological sciences, illuminates how we can reignite the sparks of joy, innovate, and recognize where improvements urgently need to be made. The key to this disruption—to seeing, feeling, and noticing again—is change. By temporarily changing your environment, changing the rules, changing the people you interact with—or even just stepping back and imagining change—you regain sensitivity, allowing you to more clearly identify the bad and more deeply appreciate the good.Our guest is: Cass R. Sunstein, who is the nation’s most-cited legal scholar. For the past fifteen years, he has been at the forefront of behavioral economics. From 2009 to 2012, he served as the administrator of the White House Office of Information and Regulatory Affairs. Since that time, he has served in the US government in multiple capacities and worked with the United Nations and the World Health Organization, where he chaired the Technical Advisory Group on Behavioral Insights and Sciences for Health during the COVID-19 pandemic. He is the Robert Walmsley University Professor at Harvard Law School. His book Nudge, coauthored with Richard Thaler, was a national bestseller. In 2018, he was the recipient of the Holberg Prize from the government of Norway, sometimes described as equivalent of the Nobel Prize for law and the humanities. He lives in Boston and Washington, DC, with his wife, children, and labrador retrievers. He is the co-author [along with Tali Sharot, who could not join us for this episode] of Look Again.Our host is: Dr. Christina Gessler, who is the creator of the Academic Life podcast. She holds a PhD in history, which she uses to explore what stories we tell and what happens to those we never tell.Welcome to Academic Life, the podcast for your academic journey—and beyond!
