Movie reconstruction from mouse visual cortex activity

High-quality reconstructions of 10-second movies from mouse visual cortex activity can be achieved using two-photon calcium imaging data, with a 2-fold increase in pixel-by-pixel correlation compared to static images.

Hierarchy of prediction errors shapes the learning of context-dependent sensory representations

Context shapes sensory processing in the brain, with layer 2/3 somatosensory neurons enhancing reward response and lateral orbitofrontal cortex signaling loss of confidence in outcome prediction.

Discretized representations in V1 predict suboptimal orientation discrimination

Discretized representations in V1 neurons in sensory cortices predict suboptimal orientation discrimination in mice, as they relocate activity to task-relevant domains.
