Check out our new modelling paper, now on Biorxiv! https://www.biorxiv.org/content/10.1101/2020.01.28.921205v1 … We simulate how one can decode cortical alpha oscillations to identify memories by their unique temporal signatures, via some very cool binding and timing mechanisms.

"In HC, smaller ... vascular dilations in response to ... neuronal activity produce smaller positive BOLD signals. BOLD signals are therefore a less sensitive measure of neuronal activity in HC than in neocortex".

Are nonlinear classifiers useless when analyzing fMRI data? Empirically we see some evidence: https://hal.archives-ouvertes.fr/hal-02276649/document … My take: ML in the high input noise domain will always be approximately linear, even in the limit of infinite data. w
