Electron microscope image of neurons in the cerebellum. This slice through the cells in the cerebellum shows a dendritic branch of a Purkinje cell and its side arms (yellow) receiving several ...

In a groundbreaking achievement, Princeton University scientists have fully mapped the brain of an adult fruit fly, Drosophila melanogaster, unlocking new insights into how brains work. The feat marks ...

A newly described technology improves the clarity and speed of using two-photon microscopy to image synapses in the live brain. The brain's ability to learn comes from "plasticity," in which neurons ...

Electron microscope image of synapse in the cerebellum. This slice through the cerebellum cells shows the synapse between an inhibitory neuron (red) and a Purkinje cell (yellow). There, the tiny ...

Researchers have built a tiny, lightweight microscope that captures neuron activity with unprecedented speed that can be used in freely moving animals. The new tool could give scientists a more ...

The brain’s rules seem simple: Fire together, wire together. When groups of neurons activate, they become interconnected. This networking is how we learn, reason, form memories, and adapt to our world ...

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 ...

Scientists in Japan say they have reversed the signs of Alzheimer’s disease in lab mice by restoring the healthy function of synapses, critical parts of neurons that shoot chemical messages to other ...

Whether picking up a small object like a pen or coordinating different body parts, the cerebellum in the brain performs essential functions for controlling our movement. Researchers investigated how a ...
