Changing Your Mind: Scientists Disrupt Specific Memories in People

This may seem like old news. Thanks to Will Smith’s “neuralizer” blasting away horrific memories of alien attacks in the 1997 movie “Men in Black,” and the quest to bury the heartbreak of a broken romance in the 2004 flick “Eternal Sunshine of the Spotless Mind,” the concept of erasing memory has become commonplace. Continue reading

How can we enhance working memory?

Even a seemingly simple behavior–like trying to remember if the name of the person you just met is “Elizabeth” or “Patricia”–can tax our memories. These short-term memory drains are part of what we neuroscientists call “working memory”.
When you think about it, it’s quite a remarkable neural feat that we can do this at all! Somehow our brains are able to take in information (like the sound waves that hit our ears in just the right way to make us perceive the sound that is the name “Patricia”), hold that information in some neural pattern/buffer/code, and then retrieve that information at will (if we’re lucky).

Patient Zero: What We Learned from H.M.

Memory is our most prized human treasure. It defines our sense of self, and our ability to navigate the world.  It defines our relationships with others – for good or ill – and is so important to survival that our gilled ancestors bear the secret of memory etched in their DNA. If you asked someone over 50 to name the things they most fear about getting older, losing one’s memory would be near the top of that list. There is so much worry over Alzheimer’s disease, the memory thief, that it is easy to forget that our modern understanding of memory is still quite young, less than one, very special lifespan.

Meet the Patient Zero of memory disorders, H.M.

T-Shirt

Brain activity tracks the preferences of others.

A new study published by Izuma and Adolphs in Neuron asks what are the brain areas that undergo changes in activity when we modify our preferences to fit social context1. Imagine I show some people a shirt and ask them whether they like it or not. In some cases I tell people that this is the favorite shirt of a certain group of University students. In other cases I tell them that it is the preferred shirt of most criminals. What we get is a socially-manipulated preference – people tend to dislike the criminal’s favorite. Continue reading

Letters to a young scientist

Born scientist.

It is a quite modest title that Edward O. Wilson has chosen for the book he published this month, Letters to a Young Scientist. As I began to read, I was expecting to find a list of more or less useful tips and tricks on how to become a scientist. What I instead found in this book is a deep personal reflection on what science really is and how scientists come to do it. Continue reading

On Boylston Street

The last time I was on Boylston Street it was to give a lecture in November at a scientific meeting in the Weston Hotel.  Today, Sunday, I’m looking out onto an empty street, barricaded.  An eerie modern-day ghost town festooned with yellow police tape rippling in the cold Boston wind.  Continue reading
