Recent progress in fluorescent sensors of neural activity, along with key advances in hardware development, are revolutionizing our ability to use imaging to understand brain function at both the cellular and large-scale network levels.

This special section will highlight some of the emerging technologies underlying this revolution, as well as some applications of in vivo fluorescent imaging to visualize brain function.

Key topics that will be addressed include:

• novel genetically encoded fluorescent sensors
• microscopes for in vivo imaging
• elucidating brain function via fluorescence imaging
• development of computational analysis methods

A cover letter indicating that the submission is intended for this special section should be included with the paper. All submissions to the special section will be peer reviewed, and papers will be published online in advance of print.

Neurophotonics will become a fully open access journal on 1 January 2019, and beginning 1 July 2018, all authors will be required to pay the $1675 open access fee. Discounts are available for SPIE members and people belonging to institutions that subscribe to the SPIE Digital Library.
