Scientists map the frontiers of vision
There's a 3-D world in our brains. It's a landscape that mimics the outside world, where the objects we see exist as collections of neural circuits and electrical impulses.

Control of fear in the brain decoded
When healthy people are faced with threatening situations, they react with a suitable behavioural response and do not descend into a state of either panic or indifference, as is the case, for example, with patients who suffer ...

Research uncovers dynamic changes in the epigenome that occur during brain circuitry formation
Changes in the epigenome, including chemical modifications of DNA, can act as an extra layer of information in the genome, and are thought to play a role in learning and memory, as well as in age-related cognitive decline. ...

Neuroscientists posit that brain region is a key locus of learning
Small and seemingly specialized, the brain's locus coeruleus (LC) region has been stereotyped for its outsized export of the arousal-stimulating neuromodulator norepinephrine. In a new paper and with a new grant from the ...

Transposons could be rewiring our brains
A new study by neuroscientists at the University of Oxford shows that mobile genetic elements that were active in the genomes of our ancestors could be closely linked to important functions in our brain and might help diversify ...

Reward improves visual perceptual learning—but only after people sleep
Past studies have found that rewarding participants during a visual perceptual task leads to performance gains. However, new research suggests that these performance gains occur only if participants follow up the task with ...
