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 ...

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 ...

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 ...

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 ...

Recording electrical signals from inside a neuron in the living brain can reveal a great deal of information about that neuron's function and how it coordinates with other cells in the brain. However, ...

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 ...

Understanding how new neurons affect brain function throughout adulthood can offer new approaches to treating epilepsy and dementia. When you purchase through links on our site, we may earn an ...

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 ...
