How does variability in activity impact decision-making? Using CNNs, we show that trial-level variability reflects decisions with: (i) strong sensory evidence, (ii) low discriminability and (iii) sensory evidence provides conflicting information. www.biorxiv.org/content/10.1...

The brain has many neurotransmitter and neuromodulators, but which ones are driving brain activity at any moment? Using PET derived neuroreceptor maps we show that BOLD signal is driven by two neuroreceptors modules. www.nature.com/articles/s42...

We introduce a remnant functional networks-based framework to compare how functional connectivity is shaped by physical and molecular factors -- structural connectivity, physical distance, genetic and neuroreceptor congruence. direct.mit.edu/netn/article...

Here we leverage trial-to-trial fluctuations in the brain-wide signal recorded using functional MRI to test if distinct sets of brain regions are activated on different trials when accomplishing the same task. www.nature.com/articles/s41...
