Brain Scans and Bold Plans: Our Interview with Matt Wall

Sometimes, a conversation takes you to places you never would’ve expected. Matt Wall and I struck up a chat about brain-scanning technology early this year, and he mentioned that he’d like to do an interview for The Connectome. Since he’s got 5+ years of published brain research under his belt, I jumped at the chance. […]

Becoming Bad

The brains of psychopaths are anatomically different from healthy brains in a specific set of ways, says a new study. Areas of the brain that enable us to feel guilt and fear, and to understand other people’s emotions – particularly the anterior rostral prefrontal cortex and the temporal poles – are significantly smaller in psychopathic […]

Why I Love and Hate "Game"

Yes, it’s that special time of year again – time for flamboyant bouquets and chalky candy to appear at office desks – time for Facebook pages to drown in cloying iconography – time for self-labeled “forever aloners” to dredge the back alleys of OKCupid in last-ditch desperation – and time for me to load up my trusty gatling […]

Sacred Values

Principles on which we refuse to change our stance are processed via separate neural pathways from those we’re more flexible on, says a new study. Our minds process many decisions in moral “gray areas” by weighing the risks and rewards involved – so if the risk is lessened or the reward increased, we’re sometimes willing […]

Stress Intervention

Scientists have discovered a way to shut down the brain’s “stress process” before it gets going, says a new study. By blocking the brain’s ability to manufacture certain chemicals called neurosteroids, researchers have managed to temporarily cut off a biological process crucial for stressful behavior – and for many stressful feelings as well. Animals from amphibians […]

Harry Potter and the Nature of the Self

Yup, this is what we’re doing today. I finally got to see Deathly Hallows Part 2, and it got me thinking about neuroscience like frickin’ everything always does, and I came home and wrote an essay about the nature of consciousness in the Harry Potter universe. And we’re going to talk about it, because it’s […]

Chemical Parasites

A certain brain parasite actually turns off people’s feelings of fear by increasing levels of the neurotransmitter chemical dopamine, says a new study. Toxoplasma gondii, a parasitic protozoan (a kind of single-celled organism), mostly likes to live in the brains of cats – but it also infects birds, mice, and about 10 to 20 percent of people in the U.S. […]

Digital Friendships

Those of us who have loads of Facebook friends tend to have greater development in several specific brain regions, says a new study. Researchers have found a strong correlation between large numbers of Facebook connections and increased development of gray matter – tissue containing neuron cell bodies, where dense communication occurs – in several regions crucial […]

Modified Memories

Each time we retell a story, our actual memories of its events change, says a new study. When we receive hints – true or not-so-true – about a story’s details from our friends, we often revise our version if what they say makes sense to us. But what’s incredible is, it isn’t just our retelling […]

The Sound of Fear

A certain inaudible sound frequency may directly trigger feelings of “creepiness” and physical symptoms of fear, one scientist says. A sound frequency of around 19hz – just below the range of human hearing – has been detected in several “haunted” places, including a laboratory where staff had reported inexplicable feelings of panic, and and a pub […]
