having read that, and because I am a whole brain imager, I am wondering, are (almost) all the MEEG and fMRI signals we measure active inhibition? @fmri-today.bsky.social @practicalfmri.bsky.social @benhayden.bsky.social @danielemarinazzo.bsky.social @robertoostenveld.bsky.social
super cool study: www.cell.com/neuron/fullt...
A latent pool of neurons silenced by sensory-evoked inhibition can be recruited to enhance perception
Gauld et al. use all-optical interrogation to probe sparse coding in the barrel cortex.
They find that targeted photostimulation of task-silent neurons evokes perceptual

From sensory to perceptual manifolds: The twist of neural geometry
The brain uses geometric twists to expand neural dimensionality, thus untangling perception from sensation.

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.
