When Choosing Your Next Move, Your Brain Is Always Ready for Plan B

Whether we're navigating a route to work or browsing produce at the grocery store, our brains are constantly making decisions about movement: Should I cross the street now or at the intersection? Should I reach for the red apple or the green apple? When you're presented with two options, your brain's motor neurons prep for both possibilities before you've decided which action to take...

Older, Fitter Adults Experience Greater Brain Activity While Learning

Older adults who experience good cardiac fitness may be also keeping their brains in good shape as well. In what is believed to be the first study of its kind, older adults who scored high on cardiorespiratory fitness (CRF) tests performed better on memory tasks than those who had low CRF. Further, the more fit older adults were, the more active their brain was during learning.

Study Raises Hope that Autism Behaviours May be Reversible

About 1 percent of people with autism are missing a gene called Shank3, which is critical for brain development. Without this gene, individuals develop typical autism symptoms including repetitive behaviour and avoidance of social interactions. In a study of mice, MIT researchers have now shown that they can reverse some of those behavioural symptoms by turning the gene back on later in life...

Brain ‘Reads’ Sentences the Same in English, Portuguese

When the brain "reads" or decodes a sentence in English or Portuguese, its neural activation patterns are the same, new research shows. The study is the first to show that different languages have similar neural signatures for describing events and scenes.

Electric Brain Stimulation During Sleep Can Boost Memory

For the first time, scientists report using transcranial alternating current stimulation, or tACS, to target a specific kind of brain activity during sleep and strengthen memory in healthy people.

How the Brain Builds Panoramic Memory

When asked to visualise your childhood home, you can probably picture not only the house you lived in, but also the buildings next door and across the street. MIT neuroscientists have now identified two brain regions that are involved in creating these panoramic memories.

Early Brain Connections Key to Reading

A study reveals that a brain region dedicated to reading has connections necessary for that skill even before children learn to read. By scanning the brains of children before and after they learned to read, the researchers found they could predict the location where each child's visual word form area (VWFA) would develop.

Harry Potter Reveals Secrects of the Brain

Carnegie Mellon University scientists used a chapter of the book Harry Potter and the Sorcerer's Stone to identify what different regions of the brain are doing when people read. Researchers performed functional magnetic resonance imaging (fMRI) scans of participants as they read the chapter.

Dyslexic Readers Have Disrupted Network Connections in the Brain

A new study in Biological Psychiatry maps the circuitry of dyslexia. Compared to typical readers, dyslexic readers had weaker connections between areas that process visual information and areas that control attention, suggesting that individuals with dyslexia are less able to focus on printed words.

Children with Autism Have Extra Synapses in Brain, Study Finds

Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain “pruning” process during development, according to a study by neuroscientists at Columbia University Medical Center (CUMC).
