Glad to sharing our new paper addressing timing issues between video features and BOLD responses during movie watching. And we showed that deconvolution can be done using continuous feature time series as inputs to derive hemodynamic response functions (HRFs).

fMRI signals “up,” but neural metabolism might be going “down.” In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funds @erc.europa.eu #neuroskyence 🧵:
