Syncing electrophysiological data with experiment relevant timestamps is crucial for making any meaningful sense of what the ~3 pound organ between our ears is up to. To address this, a group of graduate students from the University of Florida Biomedical Engineering and Neuroscience Departments developed FROST, a system for synchronizing experimental and electrophysiological data. This open source system is built around an Arduino-based microcontroller for analog and digital input and synchronization combined with a custom printed circuit board. In their recent Journal of Neuroscience Methods publication, Jose Alcantara and colleagues describe the development and benefits of this system compared to commercial alternatives. Further, they provide data to demonstrate the implementation of FROST in experiments with human and rodent subjects. The project is described at length in the publication, and the build list, custom files, and firmware code are openly available from GitHub (with a fun insight to the brainstorm process that gave rise to FROST).

This research tool was created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the tool was described, and include an RRID in the Materials and Methods of your future publications.  RRID:SCR_022344
