Functional digital twins found that when and whether a surround facilitates or suppresses the optimal center feature depends on how congruent the surround is given that feature under natural scene statistics, consistent with hierarchical Bayesian inference.
A dual coding architecture in anterior IT is suggested: shared low-dimensional structure supports category generalization, whereas sparse and reliably feature-random single-neuron responses expand the representational space and support efficient identification of individual visual inputs.

How is information encoded in the cerebral cortex, and how is it used? We review coding in sensory cortex, primarily in barrel cortex. Traditional single-cell analyses of barrel cortex have revealed features like somatotopy, tuning to angle of whisker deflection, and sensitivity to deflection velocity. A growing number...

It is established that an internal model of the world can serve as a primary driver of activity in sensory cortex, and under illumination, visual stimuli gain- modulated this path-invariant activity rather than replacing it with stimulus-driven responses.

Comparing brain responses across species is essential for identifying models of human cognition and testing theories of brain evolution, but differences in brain size, measurement techniques, and signal dynamics make it challenging. Here we collected dense fMRI data in macaques and humans using the same movies, static-...

Computational hypotheses about brain information processing can be expressed in neural network models. Neuroscientists have begun to compare such models in terms of their alignment with neural and behavioural data. The high parametric capacity of these models is essential to their ability to capture cognitive processes...

This work used a variational autoencoder to generate video clips predicted to correspond to maximal activity in each brain region, and identified a network of 11 cortical regions that support active navigation and are tuned for complex feature combinations that capture dynamic scenes that incorporate both world events...
