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 ...

For more than a century, maps of the brain have been based on how brain tissue looks under the microscope. These anatomical ...

For more than a century, maps of the brain have been based on how brain tissue looks under the microscope.

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 ...

Researchers have developed the first activity-based maps of the prefrontal cortex, challenging traditional descriptions of ...

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 ...

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, ...

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 ...
