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 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 ...

Recent technological advances facilitate the reconstruction of complete brain connectomes in small organisms and partial connectomes in mammals, involving the mapping of the network of neurons and ...

When we form a memory, brain cells need to deliver supplies to strengthen specific neural connections. A new study from MPFI and Weill Cornell Medicine has revealed how two cellular switches, Rab4 and ...

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

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 ...

A detail of a figure from the paper shows synapses formed between a neuron (above) and muscle (below) a narrow cleft. The distinct T-bar shape indicates an active zone. In the upper image, the synapse ...
