How genetic variation gives rise to differences in mathematical ability

DNA variation in a gene called ROBO1 is associated with early anatomical differences in a brain region that plays a key role in quantity representation, potentially explaining how genetic variability might shape mathematical ...

Humans are born with brains 'prewired' to see words

Humans are born with a part of the brain that is prewired to be receptive to seeing words and letters, setting the stage at birth for people to learn how to read, a new study suggests.

Skin breaks down with prolonged AL/CVL use in neonates

(HealthDay)—Neonates with prolonged arterial line (AL)/central venous line (CVL) use have fewer skin breaks and have significantly larger thalamic volumes early in life compared with those with restricted line use, according ...

New research reveals why low oxygen damages the brain

Brain cell dysfunction in low oxygen is, surprisingly, caused by the very same responder system that is intended to be protective, according to a new published study by a team of researchers at the Case Western Reserve University ...

Scientists take major step toward Angelman Syndrome gene therapy

Babies born with a faulty maternal copy of the UBE3A gene will develop Angelman syndrome, a severe neurodevelopmental disorder with no cure and limited treatments. Now, for the first time, scientists at the UNC School of ...

Could reducing painful procedures help premature infants' brains?

Premature infants born earlier than 28 weeks gestation who experience fewer needle pokes while receiving life-saving care in the neonatal intensive care unit may have better growth of a part of the brain called the thalamus. ...

Researching why our brains are able learn and memorize

The long-term potentiation (LTP) and long-term depression (LTD) of the strength of hippocampal excitatory synapse involved in learning and memory formation in brain have been separately explained, but the molecular mechanism ...

Researcher proposes new theory of consciousness

Electromagnetic energy in the brain enables brain matter to create our consciousness and our ability to be aware and think, according to a new theory developed by Professor Johnjoe McFadden from the University of Surrey.

Rethinking the link between cannabinoids and learning

Cannabinoids have a strong influence on how our brains work and how we behave. Many people are only aware of the recreational aspect of cannabinoids. But in fact these molecules naturally exist in our brains where they participate ...
