Beyond the Surface: Unlocking the Brain with fNIRS
1 h 36 hybrid session (in person in Coimbra and online via Google Meet) with IEEE UC Student Branch and EMBS Coimbra. Prof. Bruno Direito (biomedical engineer at the University of Coimbra — neuroimaging, brain–computer interfaces, biomedical signal processing) built fNIRS from first principles: neurovascular coupling as the source of the signal, the haemodynamic response function, why two near-infrared wavelengths (~750–850 nm) separate oxy- from deoxyhaemoglobin (modified Beer–Lambert), and where fNIRS wins or loses against fMRI.
Second half: optode geometry and the 3 cm inter-optode compromise, the 'banana' photon path, signal components and preprocessing, then his own work — real-time neurofeedback and BCI (a subject controlling a game by activating premotor cortex), motor learning in athletes, cognitive training, and the EEG–fNIRS relation in epilepsy. Closed with a long Q&A on open-source tooling (MNE) versus proprietary software and on how to enter the field.
