A cortical output channel for perceptual categorization

The paper identifies L5 ET neurons as a cortical output channel that acquire categorical representations during perceptual categorization tasks in mice.

Layer 5 and 6b extratelencephalic neurons encode distinct sound features in auditory cortex

The paper identifies distinct response properties of layer 5 and 6b extratelencephalic neurons in mouse auditory cortex to different sound features.

Multiplexed encoding of frequency-modulated sweep features in the inferior colliculus

This study investigates how neurons in the inferior colliculus encode frequency-modulated sound features using multiplexing strategies, finding that temporal coding and combinatorial representations are key.

Pupil-linked arousal differentially modulates cell-type-specific sensory processing

The paper examines how pupil-linked arousal modulates sensory processing in different cell types of the auditory cortex in awake mice, revealing cell-type-specific effects on response magnitude, frequency selectivity, and decoding accuracy.

Canonical cortical architecture supports the emergence of noise-invariant auditory representations

The paper investigates how noise-invariant auditory representations emerge in the auditory cortex by analyzing the response patterns of different excitatory neuron subpopulations in mice.

Cell-type-specific plasticity in synaptic, intrinsic, and sound response properties of deep-layer auditory cortical neurons after noise trauma

This study investigates cell-type-specific plasticity in deep-layer auditory cortical neurons after noise trauma, finding shifts in synaptic input and response properties in corticothalamic neurons.

Primary auditory cortex is necessary for the acquisition and expression of categorical behavior

This study shows that the primary auditory cortex is necessary for categorizing auditory stimuli and maintaining consistent behavior during learning.

Symmetry in frontal but not motor and somatosensory cortical projections

The paper compares topographic precision of ipsilateral and contralateral cortical projections in frontal, motor, and somatosensory areas of mice, finding stronger contralateral projections in frontal regions.

Auditory Corticothalamic Neurons are Recruited by Motor Preparatory Inputs

The paper identifies that motor preparatory inputs activate auditory corticothalamic neurons before orofacial movements in mice.

Cellular and widefield imaging of sound frequency organization in primary and higher-order fields of the mouse auditory cortex

The paper uses imaging techniques to map sound frequency organization in mouse auditory cortex fields, identifying new areas and clarifying tonotopic organization.

Optimizing optogenetic stimulation protocols in auditory corticofugal neurons based on closed-loop spike feedback

The paper optimizes optogenetic stimulation protocols in auditory corticofugal neurons using closed-loop spike feedback to enhance or suppress midbrain firing rates.

Parallel systems for sound processing and functional connectivity among layer 5 and 6 auditory corticothalamic neurons

The paper investigates functional connectivity and sensory processing differences between layer 5 and 6 corticothalamic neurons in the mouse auditory cortex using optogenetic recordings.

Dynamic gain adjustments in descending corticofugal outputs from auditory cortex compensate for cochlear nerve synaptic damage

The paper shows that auditory cortex projection neurons adjust their gain after cochlear nerve damage, leading to increased excitability and potential network dysfunction in tinnitus.
