“Senses That Bleed” — Podcast 5: David Eagleman

On episode 5 of the Connectome podcast, I chat with David Eagleman, author of the international bestseller Incognito: The Secret Lives of the Brain. Eagleman’s lab mainly studies the ways our brains encode sensory perceptions – but as you’ll hear, he’s also fascinated by questions on the nature of consciousness, synesthesia, meaning and representation, and […]

“Using Worms to Crack the Human Brain” — Podcast 4: Scott Emmons

On episode 4 of the Connectome podcast, I chat with Scott W. Emmons, Ph.D., a professor of neuroscience and genetics at Albert Einstein College of Medicine. Dr. Emmons talks about his cutting-edge connectomics research, which may help us understand how neural circuits “decide” on a particular behavior. Though his recent work focuses on the nervous […]

The Lurking Lizard

He has haunted us for more than fifty years – this strange scientist, with his theory of primal reptiles embedded in each of us. And for years I wondered, Could this bizarre hypothesis be true? Might it explain the ancient instincts – so contrary to my intentions – which I felt arising from the depths […]

Brains and Brilliance

Where in the brain, exactly, is intelligence? Is a high I.Q. just a result of a flawed test – or do high-I.Q. brains have specific, measurable differences from others? Answers await, Intrepid Reader – but first we have to make sure we’re asking the right questions. Let’s start with the big news: a study just published […]

The Intelligence Network

Intelligence isn’t a single process – but it still depends on the coordinated activity of some specific brain areas, a new study reports. In one of the most sweeping surveys in neuroscience history, researchers put patients with various types of brain damage through a battery of cognitive tests, and pinpointed the neural correlates of “general […]

The Brain Grid

Connections in the brain aren’t all tangled up – they’re organized into a grid of tightly-knit bundles, says a new study. By applying mathematical analysis to the latest imaging technology, scientists have discovered that connective pathways are knit into a three-dimensional geometric pattern. When scientists first set out to map the connections in a brain, […]

Saving Faces

A brain area that’s specialized to recognize faces has a unique structure in each of our brains – and mapping that area’s connectivity patterns can tell us how each of our brains use it, says a new study. The fusiform gyrus in the temporal lobe plays a part in our recognition of words, numbers, faces, […]

Surprising Synchrony

Our corpus callosum is a bundle of fibers that allows our brains’ left and right hemispheres to communicate – but even in people born without these connections, the hemispheres are still somehow able to synchronize their activity, reports a new study. The brains of people born with a condition called agenesis of the corpus callosum (AgCC) […]

Hypnotized Eyes

A state of hypnosis creates detectable changes in a person’s eye movement patterns, says a new study. The “glazed” look of a person who’s been hypnotized can be linked to measurable, quantifiable changes in the patterns of that person’s reflexive eye movements – changes that non-hypnotized people aren’t able to replicate. The exact nature – and even […]

The Roots of Consciousness

The origins of subjective consciousness probably lie in an introspective brain network common to most mammals, says a new study. When we “zone out” and let our minds wander, a functional (as opposed to structural) brain network known as the default mode network (DMN) becomes active. The DMN links our frontal lobe – an area associated with planning […]
