New research challenges the century-old practice of mapping the brain based on how tissue looks under a microscope. By analyzing electrical signals from thousands of neurons in mice, scientists ...

Researchers developed a tiny, lightweight microscope that captures the electrical spikes of neurons at hundreds of frames per second in awake animals. WASHINGTON — Researchers have built a tiny, ...

Exactly what’s going on up there? The first-ever map of a 1-cubic-mm fragment of human brain has been completed, after 10 years, and the findings have thrown up numerous surprises. Keep in mind, as ...

The brain’s ability to learn comes from “plasticity,” in which neurons constantly edit and remodel the tiny connections called synapses that they make with other neurons to form circuits. To study ...

In the late 1800s, Spanish neuroscientist Santiago Ramón y Cajal drew hundreds of images of neurons. His exquisite work influenced our understanding of what they look like: Cells with a bulbous center ...
