In addition to these original research papers and reviews, Neurophotonics is publishing tutorials as well as news and comment items. Tutorials provide an opportunity for authors who have developed or perfected an important tool or method to document how others can utilize the approach for their own research. The published tutorials will have tremendous impact in our rapidly advancing field, which is highly dependent on the development, advancement, and dissemination of new tools. News and comment pieces are being published, recognizing that the breadth of our field and the rapid advancements require this special category to permit the dissemination of information about recent workshops, advances, and opportunities. Two tutorials and four news and comment items have been published to date, and more are being solicited. Please let me know if you have a tutorial or news and comment item in mind that would be appropriate for Neurophotonics.
