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...

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.

New preprint! How can you remember an image you saw once, even after seeing thousands of them? We find a role for humble mid-level visual cortex in high-capacity, one-shot learning. doi.org/10.1101/2025.09.22.677855 🧵🧪1/
Neuronal signatures of successful one-shot memory in mid-level visual cortex
High-capacity, one-shot visual recognition memory challenges theories of learning and neural coding because it requires rapid, robust, and durable representations. Most studies have focused on the hip...

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...

Cutting $20 billion to NIH over 25 years may save $500 billion on paper, but it’d end up costing $8.2 trillion in lost human health.
But NIH isn't the only thing being cut. The budget also slashes all NSF-funded science by 73 percent. NASA faces “the biggest single-year cut to NASA in history."

Donald Trump’s proposed budget would gut American science
It would slash cancer research, drug trials, space exploration, and so much more.

Linking neural population formatting to function
Animals capable of complex behaviors tend to have more distinct brain areas than simpler organisms, and artificial networks that perform many tasks tend to self-organize into modules (1-3). This sugge...

Hello! I'm excited for my first post to be a plug for the work of our terrific collaborators, Deying Song and Chengcheng Huang, with Doug Ruff in my lab. Deying created a circuit model of divisive normalization that explains & predicts many experimental results: www.biorxiv.org/content/10.1...
Neuronal heterogeneity of normalization strength in a circuit model
The size of a neuron's receptive field increases along the visual hierarchy. Neurons in higher-order visual areas integrate information through a canonical computation called normalization, where neur...
