What is it about?
A Fabry-Perot cavity milled with a focused ion beam on a tapered fiber tip is proposed for in vivo neural activity recording as an optical method. Optical fiber micro-tips are good candidate devices for sensing applications in a small volume and difficult to access locations, such as neuroscience research.

Why is it important?
Optical signals and electrical neural activity from the rat somatosensory cortex were simultaneously recorded. This fiber-based probe promises the enhanced ability to .extracellular recording of the neural activity in neurophotonics applications.
Perspectives
A single fiber optic probe can be used for simultaneous optical stimulation and optical recording.
