We all have moments of wondering, “Why did I make that decision? Why did my brain want to do that?” Teagan Wall has devoted her career to studying questions like these, and she joins Ben today to talk about the … Continue reading “Making Better Decisions… Scientifically” – Podcast 15: Teagan Wall
New neuroscience discoveries about consciousness keep popping up all the time — but where’s the line between abstract philosophy and hard science? On Episode 14 of The Connectome Podcast, Ben is joined by Bernard Baars, one of the founding fathers … Continue reading “The Hard Science of Consciousness Research” – Podcast 14: Bernard Baars
Just a minute of physical exertion can seriously impair a person’s memory of the threat that triggered it, says a new study. When we undergo a strenuous task, such as a chase or a fight, immediately after witnessing an event, we have much less ability to remember the event’s details than if we’d taken time to process what we’ve seen. This calls the concept of eyewitness testimony into serious question. As I’ve written here and Jonah Lehrer has written here, our memories aren’t nearly as static as we might like to think. In fact, each time we recall a memory, … Continue reading Mixed-Up Memories
I’ve just returned from a thrilling weekend at the BIL Conference in Long Beach, California (yes, the pun on “TED” is very intentional) where I met all kinds of smart, fun people – including lots of folks who share my love for braaaiiins! So I thought I’d introduce you guys to some of the friends I made. I think you’ll be as surprised – and as excited – as I am. Backyard Brains Their motto is “neuroscience for everyone” – how cool is that? They sell affordable kits that let you experiment at home with the nervous systems of insects … Continue reading Neuroscience Friends!
This photo got me thinking. Only 24 percent? Really? We’re finding weird new exoplanets every day – hell, NASA hasn’t even ruled out the possibility that there could be life on Europa and Titan, two moons in our own solar system – yet so many people have lost faith in space’s limitless potential to surprise us. But we’re entering an age when that potential is no longer the exclusive domain of first-world governments and media conglomerates. The fact that we even have a contest like Google’s X Prize proves that independent space exploration is becoming a very real possibility for … Continue reading Consider This an Invitation
Having trouble remembering where you left your keys? You can improve with a little practice, says a new study. It’s an idea that had never occurred to me before, but one that seems weirdly obvious once you think about it: people who train their brains to recall the locations of objects for a few minutes each day show greatly improved ability to remember where they’ve left things. No matter what age you are, you’ve probably had your share of “Alzheimer’s moments,” when you’ve walked into a room only to forget why you’re there, or set something down and immediately forgotten … Continue reading Forget Me Not
As our brains learn something, our neurons form new connections in clustered groups, says a new study. In other words, synapses – connections between neurons – are much more likely to form near other brand-new synapses than they are to emerge near older ones. As our neuroscience friends like to say: “Cells that fire together wire together” – and that process of rewiring never stops. From before you were born right up until this moment, the synaptic pathways in your brain have been transforming, hooking up new electrochemical connections and trimming away the ones that aren’t needed. Even when you’re … Continue reading Connection Clusters
