Calcium Imaging in Vivo: How to Correctly Select and Apply Fiber Optic Photometric Indicators.
Fiber-photometric is a novel optogenetic method for recording neural activity in vivo, which allows the use of calcium indicators to observe and study the relationship between neural activity and behavior in free-ranging animals. Calcium indicators also convert changes in calcium concentration in cells or tissues into recordable fluorescent signals, which can then be observed using the system of fiber-photometric. To date, there is a paucity of relevant literature on the proper selection and application of fiber-photometric indicators. Therefore, this paper will detail how to correctly select and apply fiber-photometer indicators in four sections: the basic principle of optical fiber photometry, the selection of calcium fluorescent probes and viral vector systems, and the measurement of specific expression of fluorescent proteins in specific tissues. Therefore, the correct use of suitable fiber optic recording indicators will greatly assist researchers in exploring the link between neuronal activity and neuropsychiatric disorders.
期刊介绍：
Organogenesis is a peer-reviewed journal, available in print and online, that publishes significant advances on all aspects of organ development. The journal covers organogenesis in all multi-cellular organisms and also includes research into tissue engineering, artificial organs and organ substitutes.
The overriding criteria for publication in Organogenesis are originality, scientific merit and general interest. The audience of the journal consists primarily of researchers and advanced students of anatomy, developmental biology and tissue engineering.
The emphasis of the journal is on experimental papers (full-length and brief communications), but it will also publish reviews, hypotheses and commentaries. The Editors encourage the submission of addenda, which are essentially auto-commentaries on significant research recently published elsewhere with additional insights, new interpretations or speculations on a relevant topic. If you have interesting data or an original hypothesis about organ development or artificial organs, please send a pre-submission inquiry to the Editor-in-Chief. You will normally receive a reply within days. All manuscripts will be subjected to peer review, and accepted manuscripts will be posted to the electronic site of the journal immediately and will appear in print at the earliest opportunity thereafter.
