New preprint from the lab! 🎉
Postdoc Keon Allen led this study exploring how subjects combine sources of sensory information, including unfamiliar & cross-modal cues, and what that can tell us about decision-making, neural mechanisms, and neurodiversity.

Behavioural and neuronal insights into multisensory combination of unpracticed cues.
Effective decision-making requires integrating multiple information sources, weighted by their reliability and context. While classic studies show near-optimal cue combination with well-learned signal...

First author Ramanujan Srinath demonstrated some of the things that make him a great scientist: he thinks deeply & creatively, brings together many forms of evidence & people, and is determined and innovative. He is on the job market this year and will run an incredible lab – don’t miss out! 5/

Ramanujan Srinath collected & analyzed many data sets including Amy Ni’s, Yunlong (Draco) Xu & Brent Doiron modeled, & Doug did a causal experiment. The key is: when noise and signal come from the same circuit (they must!), then smart, flexible decisions have a strong relationship with noise. 4/

One of the joys of being a scientist is the ability to think about a problem for a long time. Our new preprint solves a mystery that has been bugging me since I was a graduate student (which was, ahem, a while ago). 🧪🧠🧵1/

Guided by Noise: Correlated Variability Channels Task-Relevant Information in Sensory Neurons
Shared trial-to-trial variability across sensory neurons is reliably reduced when perceptual performance improves, yet this variability is low-dimensional, so it could be ignored by an optimal readout...
