Homer3 is a open source MATLAB application used for analyzing fNIRS data to obtain estimates and maps of brain activation. It is a continuation of the work on the well-established HOMER2 software which itself evolved since the early 1990s, first as the Photon Migration Imaging Toolbox, then as HOMER.
Homer3 is developed and maintained by the Boston University Neurophotonics Center.
