Astrocytes are found throughout the brain. Each astrocyte is in contact with several neurons and more than 100'000 synapses. A new study shows that, at the microscopic level, dozens of synapses from ...

In the brain, highly specific connections called synapses link nerve cells and transmit electrical signals in a targeted manner. Despite decades of research, how synapses form during brain development ...

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 ...

Scientists at Yale and the University of Connecticut have taken a major step in understanding how animal brains make decisions, revealing a crucial role for electrical synapses in “filtering” sensory ...

The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, 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 ...

Insights from advanced imaging technology show how neurons communicate at the atomic level for the first time. For the first time, scientists at The Hospital for Sick Children (SickKids) used advanced ...
