This month's episode of Brain Science features Mark Humphries, author of The Spike: An Epic Journey Through the Brain in 2.1 Seconds. We explore how the brain uses electrical signaling in surprising ways, beginning with a look at how an action potential (aka. "the spike") is produced. Then we consider what Humphries calls "the dark neurons," which are neurons that rarely generate spikes. We explore their role and also how it relates to the brain's spontaneous activity. One of the more surprising recent discoveries in ne...

Food shocks and how to avoid them
Addressing the problem of sudden food scarcity in US cities, and the up-and-coming field of computational social science.In this episode:00:45 Food shocksClimate change, the COVID-19 pandemic, and geopolitical crises can cause food shortages. To tackle this issue, Alfonso Mejia and colleagues have modelled how to best mitigate these food shocks in US cities. Alfonso tells us about the new analyses and what steps cities could take in the future.Research Article: Gomez et al.News and Views: How to buffer against an urban food shortage06:07 Research HighlightsA tiny lattice can withstand the impacts of projectiles at twice...

Stephen Fleming: The Science of Self-Awareness (BS 185)
Stephen Fleming (Click to play. R Clk to download)
This month's episode of Brain Science is an interview with Dr. Stephen Fleming, author of "Know Thyself: The Science of Self-Awareness." We explore the concept of metacognition and learn that while explicit metacognition (thinking about thinking) may be unique to humans, it is built on building blocks shared with other species. We also explore what can go wrong and why it matters.

Mark Solms talks about the origins of Consciousness (BS 184)
Mark Solms (click to hear MP3, right click to download)
In this month's episode of Brain Science, neuroscientist Mark Solms talks about his new book "The Hidden Spring: A Journey to the Origins of Consciousness." Solms was inspired by the pioneering work of Jaak Panksepp who argued that the origins of consciousness can be traced to the brainstem. In his new book Solms presents the evidence for this viewpoint and explains how the work of computational neuroscientist Karl Friston has provided additional support. We consider the implications for our understanding of both human consciousness...

Cracking consciousness, and taking the temperature of urban heat islands
First this week, Lucia Melloni, a group leader in the department of neuroscience at the Max Planck Institute for Empirical Aesthetics, talks with host Sarah Crespi about making the hard problem of consciousness easier by getting advocates of opposing theories to collaborate and design experiments to rule in or rule out their competing theories. Next, TC Chakraborty, a Ph.D. candidate at Yale University, shares his Science Advances paper on why it ’s important to measure air temperature on the ground rather than from satellites when trying to understand urban heat islands—how cities heat up more than the surrounding cou...

Jeff Hawkins describes a new theory of Intelligence (BS 183)
Jeff Hawkins has spent nearly twenty years on a quest to discover how the brain's cortex generates intelligence. In this episode he talks about his new book A Thousand Brains: A New Theory of Intelligence. Inspired by the pioneering work of Vernon Montcastle, Hawkins team at Numenta has proposed a new theory that he calls the housand brains theory. As always, Hawkins makes his work accessible to listeners and readers of all backgrounds.
