A biomimetic deep encoder for auditory restoration by cortical stimulation

This paper introduces Braincodec, a deep encoder that improves sound transmission via cortical stimulation, achieving high-fidelity sound reconstruction and matching non-implanted mice in sound discrimination.

A spatial code for temporal cues is necessary for sensory learning

The paper shows that spatial representations, not temporal patterns, are necessary for sensory learning in mice using optogenetic stimulation and neural recordings.

Context-dependent signaling of coincident auditory and visual events in primary visual cortex

The paper shows that V1 interneurons suppress auditory signals in the absence of visual input but boost visual responses when auditory and visual stimuli coincide, enabling cross-modal event detection.

Cortical recruitment determines learning dynamics and strategy

The paper shows that cortical recruitment in mice correlates with salience in reinforcement learning, demonstrating its role in stimulus association and overshadowing.
