Scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons. These ...

Alzheimer’s may destroy memory by flipping a single molecular switch that tells neurons to prune their own connections. Researchers found that both amyloid beta and inflammation converge on the same ...

Experimental electron micrograph of purified synaptic vesicles (upper). Synaptic vesicles automatically identified in the image with a new computer program are highlighted with different colours and ...

More than a century ago, the anatomist Santiago Ramón y Cajal unveiled his incredibly detailed drawings of neurons. From these, he posited that neurons were the main building blocks of the brain and ...

A collaborative French–Swiss study reveals a previously unknown role for astrocytes in the brain's information processing. Published in the journal Cell, the research shows that these glial cells are ...

(a) Schematic diagram of a biological neural network and (b) circuit schematic of an artificial neural network implemented in hardware using an artificial neuromorphic device. (c) Experimental results ...

Scientists uncover new synapse hotspots in the teen brain, challenging the old theory of synaptic pruning and its link to schizophrenia.
