#JNeurosci: When playing in a band, notes must be efficient yet flexible to tempo, dynamics, or other musicians’ actions. Using a sequential finger‑pressing task, Nazerzadeh et al show this balance comes from integrating sensory input & sequence memory

Repeated Viewing of a Film Clip Changes Event Timescales in The Brain Many everyday experiences share a recurring structure: routines, familiar routes, rewatched films, and replayed songs. How do repeated encounters with such structure alter the brain’s representations ...

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as events become familiar. Slow-timescale structure predicts memory.

How do Bayesian brains acquire priors?

Summary of the Project
This project explores how the brain constructs perceptual experience from visual input, focusing on the role of Bayesian models in perception. A key challenge in vision science is understanding how humans interpret complex scenes from the limited information available in retinal images. Modern theories suggest that perception involves probabilistic inference, where the brain integrates sensory signals with prior expectations to make sense of the world. However, the origins and nature of these expectations remain poorly understood. This research aims to advance our understanding of perceptual experience by examining how structured patterns in visual input can inform models of perception. The work spans computational modelling and experimental approaches to uncover principles that explain how visual systems interpret properties such as shape, material, and lighting from images. By addressing fundamental questions about perception, this project will contribute to psychology, neuroscience, and artificial intelligence, offering insights into how biological and artificial systems can learn to interpret complex environments.

Excited that this work with @serences.bsky.social and @timbrady.bsky.social is now out! Our Gabor-wavelet model better predicted voxel responses in scene regions than 3D models. Does this mean that scene areas aren’t “for” processing 3D scene structure? NO, we argue. 1/

There is growing interest in how cognitive control may improve value-based decision making.

However, we find that a recent paper overestimated the role of control in their task, leading to erroneous interpretations of dACC recordings.
