Princeton researchers show how the brain breaks down events

Research by Princeton University neuroscientists provides a new framework for understanding how the experience of life is accumulated, stored and recalled by the human brain.

“When you go about your day, you’re continuously assaulted with visual, auditory and other sensory information,” said Christopher Baldassano, an associate research scholar at the Princeton Neuroscience Institute (PNI). “We don’t try to understand our world as the continuous stream that’s coming in, but we break it up into pieces we can understand and remember. The goal of this research was to look for the signatures of this kind of activity.” (more…)

Sometimes, words just complicate things. What if our brains could communicate directly with each other, bypassing the need for language? (more…)

Neural sweet talk: Taste metaphors emotionally engage the brain

So accustomed are we to metaphors related to taste that when we hear a kind smile described as “sweet,” or a resentful comment as “bitter,” we most likely don’t even think of those words as metaphors. But while it may seem to our ears that “sweet” by any other name means the same thing, new research shows that taste-related words actually engage the emotional centers of the brain more than literal words with the same meaning.

Brain responses to emotional images predict PTSD symptoms after Boston Marathon bombing

The area of the brain that plays a primary role in emotional learning and the acquisition of fear – the amygdala – may hold the key to who is most vulnerable to post-traumatic stress disorder.

Researchers at the University of Washington, Boston Children’s Hospital, Harvard Medical School and Boston University collaborated on a unique opportunity to study whether patterns of brain activity predict teenagers’ response to a terrorist attack. (more…)

Using only data from an fMRI scan, researchers led by a Yale University undergraduate have accurately reconstructed images of human faces as viewed by other people.

“It is a form of mind reading,” said Marvin Chun, professor of psychology, cognitive science and neurobiology and an author of the paper in the journal Neuroimage. (more…)

Brain Scans Show We Take Risks Because We Can’t Stop Ourselves

AUSTIN, Texas — A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it’s probably not because their brains’ desire systems are too active, but because their self-control systems are not active enough.

This might have implications for how health experts treat mental illness and addiction or how the legal system assesses a criminal’s likelihood of committing another crime. (more…)

Moths Wired Two Ways to Take Advantage of Floral Potluck

Moths are able to enjoy a pollinator’s buffet of flowers – in spite of being among the insect world’s picky eaters – because of two distinct “channels” in their brains, scientists at the University of Washington and University of Arizona have discovered.

One olfactory channel governs innate preferences of the palm-sized hawk moths that were studied – insects capable of traveling miles in a single night in search of favored blossoms. The other allows them to learn about alternate sources of nectar when their first choices are not available.

For moths, the ability to seek and remember alternate sources of food helps them survive harsh, food-deprived conditions. Scientists knew bees could learn, but this is the first proof that moths can too. (more…)
