The Science of Stuttering

A special thank you to Kaja Bajc and Jaymie Horak for their incredibly helpful personal input. How is it that someone can sing fluidly but struggle to introduce herself? Or smoothly imitate a foreign accent without trouble, but get stuck on words when speaking without pretense?  Stuttering is a communication disorder characterized by disruptions (“disfluencies”) […]

Machines Comparing Circuitry (or, Understanding Our Uniquely Human Brain)

I became fascinated by the brain because I was – and continue to be – fascinated by humans. Why are we so obsessed with other people’s lives, including (sometimes especially) those whom we’ve never met? How are we able to communicate such complex emotions with a raise of an eyebrow or even just a glance? […]

Dopamine is NOT your brain’s reward chemical

Dopamine is NOT your brain’s reward chemical.  Or rather, dopamine is not JUST your brain’s reward chemical, nor is it your brain’s ONLY reward chemical.

AN update: disease in a dish

While the phrase “stem cells” used to spark bitter controversy, scientists can now take a harmless skin biopsy from a human patient and transform those (skin) cells into a bunch of stem cells capable of becoming many different types of cells in the body, including brain cells.

We are going through times of profound social change, and the Internet and all the new technologies that go along with it are huge drivers in this, allowing us to remain connected with others without actually having to connect with them.

Mind your P’s and T’s: How tainted drugs revolutionized Parkinson’s research

[En español] In 1982, a man was brought to a hospital in the Bay Area of California in a curious condition.  The man was completely catatonic (immobile), and was frozen into an awkward, statue-like posture.  Doctors initially diagnosed him with catatonic schizophrenia, a sub-type of schizophrenia characterized by rigidity and unresponsiveness. However, this diagnosis did […]

Happiness comes from within

[En español] ‘Folks are usually about as happy as they make up their minds to be’ – Abraham Lincoln. Happiness comes from within. More specifically, from the brain. Surely I am biased when I say the nervous system is incredibly interesting, but I am not the only one who thinks this. The public’s fascination with the brain most likely […]

Altruism: A Story of Amygdalae and Kidneys

So, how do you begin to study the neural underpinnings of something so difficult to define or identify? And since virtually all of us do kind things on occasion, how would one compare altruists and non-altruists to see whether there are any differences in brain structure or activity?

Technicalities of the Tingles: The science of sounds that feel good. #ASMR

“I wanted someone speaking in lightly accented English. And I wanted them talking to me about jewelry, slowly and deliberately.” — Andrea Seigel, This American Life #491: Tribes (aired March 29, 2013) Now that NeuWriteSD’s gender month is over, I thought I’d ease our readers back into the usual routine with a scientifically-stimulating but slightly […]
