Two-photon microscopy is a type of fluorescence microscopy that, rather than exciting the sample with a single photon, makes use of multiple photons. The advantage over more traditional one-photon ...

Intravital brain imaging is a valuable tool for studying neurons, glial cells, and their surroundings in living animals. It allows the investigation of neurological illnesses, therapeutic efficacy, ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

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 ...

Intravital brain imaging is a powerful method for observing neurons, glial cells, and their surrounding environments in living animals. It facilitates the study of neurological diseases, drug efficacy ...
