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.

The paper develops two new genetically encoded voltage indicators (JEDI3sub and JEDI3hyp) for improved two-photon recording of subthreshold voltage dynamics in vivo.

This paper introduces a chronically implantable μLED array for optogenetic cortical stimulation in mice, demonstrating long-term stability and effective neuronal responses.

This study shows that cortical neuroprostheses in mice outperform cochlear implants in auditory tasks, generating sound-like percepts through structured neural activity.

The paper analyzes offset responses across auditory brain regions in mice, finding that cortical offset responses provide more accurate sound encoding than subcortical ones.

The paper shows that odor and spatial information is differentially encoded in the piriform cortex and lateral entorhinal cortex of mice during odor navigation tasks.

The paper examines how sound processing in the auditory cortex changes during slow wave sleep compared to wakefulness, finding that sound representations remain geometrically distinct but are dampened and intermittently gated.

The paper shows that auditory feature representations develop gradually through stages of the auditory pathway, with specific improvements at certain stages.

The paper shows that mice use distinct cellular mechanisms to predict different levels of regularity in sound sequences, with VIP neurons signaling global structure violations during wakefulness.

The paper shows that anesthesia drastically alters single neuron sound responses in the auditory brainstem, but has minimal effect on population-level parameters.

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

This paper introduces medial forebrain bundle stimulation as a reward alternative to water deprivation in mice, enabling stable task performance without metabolic stress.

The paper shows that awake cortex forms stimulus-specific neuronal assemblies for sensory inputs, distinct from ongoing activity, while anesthesia blurs this distinction.

The paper shows that noisy neuronal populations in the dorsal inferior colliculus of awake mice encode sound location with decoding accuracy matching mouse discrimination ability.

The paper investigates how auditory neurons track sound envelopes in noisy conditions and finds that slow amplitude modulations are better tracked, affecting discrimination performance.

The paper investigates OFF responses in the auditory cortex of awake mice using population analyses of two-photon calcium recordings and compares single-cell and network models to understand their underlying mechanisms.

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.

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