WASHINGTON — Thanks to a mouse watching clips from “The Matrix,” scientists have created the largest functional map of a brain to date — a diagram of the wiring connecting 84,000 neurons as they fire ...

The mysteries of the brain have captivated scientists for more than 100 years, most notably illustrated in the detailed drawings of neuroanatomist Santiago Ramón y Cajal. These drawings and his ...

It takes just a few milliseconds: A vesicle, only a few nanometers in size and filled with neurotransmitters, approaches a cell membrane, fuses with it, and releases its chemical messengers into the ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

In a study supported by the National Institutes of Health (NIH), researchers revealed the structural underpinnings of memory formation across a broad network of neurons in the mouse brain. This work ...

The ability of single particle cryo-electron microscopy to capture structural information on samples that could not be crystallized for use with crystallographic methods or were too delicate for ...

Support grids are a key part of electron microscopy measurements; the choice of the grid can directly influence the quality and accuracy of the final image. This is particularly true for transmission ...
