Can we use HOMER eliminate overlap of haemodynamic responses in fast event related fNIRS studies
Dear researchers, thanks for reading this topic. In fast event related fNIRS studies, short and variable interstimulus intervals were used and they would lead to overlap of haemodynamic responses between the two adjacent stimuli. The other day one researcher told me that the overlap effect could be eliminate with GLM model in HOMER. Do anyone know whether it is real and how to set the parameter? Thanks for your help
GLM will absolutely do this.
You should view the lectures for our fNIRS course. We have a lecture exactly on the GLM and estimating the HRF in these cases along with a demo in Homer and an exercise. You can access it as a Homer Premium user here.
