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 ...

Scientists found our brain may organize behavior by activity patterns rather than fixed regions, reshaping how brain control ...

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue ...

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 ...

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 ...

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 ...

Scientists have engineered a protein able to record the incoming chemical signals of brain cells (as opposed to just their outgoing signals). These whisper-quiet incoming messages are the release of ...

This confocal microscope image shows midbrain neurons (red) co-expressing the mu-opioid receptor (Oprm1, white) and cannabinoid receptor 1 (Cnr1, green). The interaction of these two reward pathways ...

In-vivo imaging of the neuronal activity in mouse primary visual cortex. Left, high-resolution neuronal map; middle, high-speed neuronal activity recording captured by the two-photon microscope with ...
