This study shows that echolocating bats adjust their call timing to avoid rhythmic noise, improving perception through adaptive vocal timing.

This study integrates genomics and transcriptomics to identify molecular changes in vampire bats adapted to blood-feeding, revealing shifts in gene expression and function across multiple biological pathways.

The paper shows neurons in bat auditory cortex encode vocalization class and temporal complexity before vocal onset.

The paper examines how vocalization affects fast- and broad-spiking neurons in the auditory cortex of bats, revealing cell-type specific modulatory effects.

The paper presents a cost-effective method using photogrammetry and 3D printing to create 3D brain models and matrices for standardized brain sectioning in non-model species.

This study inhibits QPRT in human stem cell-derived cerebral organoids, revealing altered cell type distribution and metabolic stress linked to neurodevelopmental disorders.

The paper compares bat and mouse limb development using single-cell analyses to show how a conserved gene program is repurposed in bat wing formation.

This study uses auditory brainstem responses to show rapid, stimulus-specific deviance detection in the human inferior colliculus, aligning with animal findings and bridging human and animal research gaps.

The paper examines stimulus-specific adaptation in bat brains using natural distress vocalizations, finding limited SSA but context-dependent responses in frontal neurons.

This study shows that the cerebellum of fruit bats responds to sounds and predicts vocalizations with high accuracy.

The paper examines waveform shape and spike correlations in bat frontal and auditory cortex, finding distinct dynamics across regions even for similar frequency oscillations.

This study investigates deviance detection in bat auditory brainstem responses to natural stimuli, showing stronger responses to echolocation pulses than social calls or artificial sounds.

This study compares auditory cortical responses in bats and mice to repetitive stimuli, finding better signal-to-noise ratio and response suppression in bats.

The paper develops a neuron model with unbalanced synaptic weights to explain how ketamine affects auditory cortex responses differently to echolocation and communication sounds in bats.

The paper shows that acoustic context modulates sound discrimination in auditory cortex through frequency-specific adaptation and stimulus-unspecific adaptation.

This study shows that echolocation in bats reverses information flow in the fronto-auditory cortical network, with bottom-up transfer during echolocation and top-down during communication.

The paper investigates how natural sound sequences are represented in the ventral auditory midbrain of bats, finding that mutual information and redundancy increase with depth regardless of sound type.

The paper compares phase-amplitude coupling (PAC) profiles in frontal-auditory field and auditory cortex of bats, showing distinct frequency ranges for coupling in each region.

This study examines the functional connectivity between the frontal auditory field and auditory cortex in bats during spontaneous activity and auditory processing, revealing distinct coding strategies and coupling dynamics.

The paper shows that fronto-striatal oscillations predict vocal output in bats and reveal differences in theta-band coupling during echolocation and non-echolocation calls.

The paper compares auditory response properties of neurons in the bat frontal auditory field and auditory cortex, finding sparser and less precise spiking in the frontal area.
