TINY REVEAL A powerful new technique reveals tiny, message-receiving bumps that dot nerve cells’ surfaces (green), called dendritic spines, in a mouse brain. R. Gao et al/Science 2019 ...

These images, taken with fluorescent-dyed samples, show nerve-insulating cells called Schwann cells (on left) growing on a tubule, and a combination of Schwann cells and neurons aligned lengthwise ...

All of the nerve cells in the white matter that released glutamate within reach of OPCs, moreover, had something in common: no myelin insulation. Normally myelin speeds electrical impulses.

The activated immune cells primarily attack excitatory synapses, which are responsible for activating other nerve cells. As a consequence, the level of activity in neural networks decreases.

In the spines of P301S homozygous animals, immune cell populations shift: Activated microglia, including antigen-presenting subsets, as well as CD8⁺ and CD4⁺ T cells expand substantially. Strikingly, ...

A 3-D visualization of the structure at the tip of a rat nerve cell’s axon, called the synaptic bouton, reveals the machinery that allows neurons to send messages. Images: Allen Institute for ...
