How does the brain learn? Does it acquire new knowledge by creating new neural pathways or by strengthening existing ...

Summary: A study demonstrates that learning in neural networks is driven primarily by adjusting the strength of existing ...

A recent study published in Science Advances suggests that recovering from ketamine anesthesia initiates a distinct brain ...

A team of neuroscientists at the Champalimaud Centre for the Unknown, in Lisbon, has been able to map single neural connections over long distances in the brain. "These are the first measurements of ...

Could the initiation of a simple walking exercise program help older adults to reverse declines in key brain regions? A new study led by University of Maryland School of Public Health researchers adds ...

The ambitious effort to chart every neuronal connection in the brain—connectomics—has long been held back by slow, expensive, and technically demanding imaging workflows. In this proof-of-concept ...

This work establishes a valuable theoretical finding about how the spike timing dependence of inhibitory plasticity shapes recurrent network connectivity. The combination of theoretical analysis and ...

After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers found that surviving eye cells formed extra branches that restored ...

REM sleep is already called "paradoxical sleep." The body is largely still, yet the brain is highly active. In humans, this ...

When a fish holds its position against a current in a river, its brain must figure out how fast to swim and how to steer to ...
