How education may stave off cognitive decline
Neuroimaging reveals those who have spent more years studying have increased cortical thickness in the medial prefrontal cortex, anterior cingulate and orbitofrontal areas of the brain. Researchers also identified enhanced gene expression profiles in these brain regions that promote information processing and provide protection against some age-related neurodegenerative diseases....

Evidence for ancient magnetic sense in humans
A new study reveals the human brain responds to changes in the Earth's magnetic field. Future studies could provide clues into the evolution and variations of magnetoreception in humans.... Read More...
Manipulating Gene Expression in Neurons with CRISPR
By optimizing neurons with CRISPR gene editing technology, researchers will have new ways to study genetic influences on brain health and disease, a new study reports. ... Read More...
Eye Contact Prepares Brains for Social Interaction
A new neuroimaging study reveals real time eye contact is a basis for effective social communication. The study found eye contact between two people simultaneously activated the same areas of each person's brain. ... Read More...
Ritalin Has No Effect on Primate Prefrontal Cortex
Even at doses that help improve monkeys' attention, researchers observe no differences of neural activity in the prefrontal cortex after administering Ritalin.... Read More...

Study reveals the hippocampus may overlay existing mental maps with information about reward and hazard derived from food found in specific locations.... Read More...
Brain Represents Optical Illusion as Delayed Reality
Researchers report the same subset of neurons encode actual and illusory flow motion, supporting the concept Jan Purkinje proposed 150 years ago, that "illusions contain visual truth".... Read More...
