ἀνθρώποισι πᾶσι μέτεστι γινώσκειν ἑωυτοὺς καὶ σωφρονεῖν.
Like with fingerprints, no two people have the same brain anatomy, a study by researchers of the University of Zurich has shown. This uniqueness is the result of a combination of genetic factors and individual life experiences. Continue reading “Every person has a unique brain anatomy”
Some brain networks become more densely connected during adolescence while others become less so, according to a new analysis published in eNeuro of neuroimaging data collected from more than 700 children and adolescents from the Philadelphia Neurodevelopmental Cohort. These changes in network connectivity may underlie the refinement of cognitive abilities that develop during the teenage years. Continue reading “The increasingly efficient teenage brain”
MIT neuroscientists have uncovered a cellular pathway that allows specific synapses to become stronger during memory formation. The findings provide the first glimpse of the molecular mechanism by which long-term memories are encoded in a region of the hippocampus called CA3. Continue reading “Molecular mechanisms of memory formation revealed”
Spending too much time in dimly lit rooms and offices may actually change the brain’s structure and hurt one’s ability to remember and learn, indicates groundbreaking research by Michigan State University neuroscientists. Continue reading “Does dim light make us dumber?”
Humans use an ability known as theory of mind every time they make inferences about someone else’s mental state — what the other person believes, what they want, or why they are feeling happy, angry, or scared. Continue reading “Children as young as 3 have brain network devoted to interpreting thoughts of other people”
The ‘three Rs’ of reading, writing and arithmetic could become four. Random electrical stimulation, a technique that applies a gentle current through the skull, leads to a long-lasting boost in the speed of mental calculations, a small laboratory study of university students has found. Continue reading “Shocks to the Brain Improve Mathematical Abilities”
