Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

The auditory cortex morphometry predicts variations in hearing acuity: a preliminary study

The Egyptian Journal of Radiology and Nuclear Medicine
Background The auditory cortex plays a vital role in hearing acuity processing. This study aimed to evaluate the relationship between hearing acuity and the morphometry of the auditory cortex to investigate whether declines in hearing acuity correlate ...

Chronic Noise Exposure Activates Apoptosis Signaling Pathway in the Rat Auditory Cortex

Otorhinolaryngology and Facial Plastic Surgery, 2020
Background: Today, hearing disorders are one of the most common problems in an industrial society. High-intensity sounds can induce apoptosis and metabolic changes in the auditory neural pathway and auditory cortex.

Cortical transformation of spatial processing for solving the cocktail party problem: a computational model(1,2,3). [PDF]

, 2016
In multisource, "cocktail party" sound environments, human and animal auditory systems can use spatial cues to effectively separate and follow one source of sound over competing sources.

Gut–Metabolome–Proteome Interactions in Age‐Related Hearing Loss: Insights from Fecal Microbiota Transplantation and Multi‐Omics Analyses

Advanced Science, EarlyView.
Germ‐free (GF) mice receiving fecal microbiota transplantation (FMT) reveal microbiota‐dependent effects on auditory aging. Integrated metagenomic, metabolomic and proteomic profiling maps gut–inner ear network and highlights 5‐hydroxytryptophan (5‐HTP) as a microbiota‐linked metabolic hub in age‐related hearing loss (ARHL).

Category-specific responses to faces and objects in primate auditory cortex

Frontiers in Systems Neuroscience, 2008
Auditory and visual signals often occur together, and the two sensory channels are known to infl uence each other to facilitate perception. The neural basis of this integration is not well understood, although other forms of multisensory infl uences have

Subcortical circuits mediate communication between primary sensory cortical areas in mice

Nature Communications, 2021
In the primary auditory cortex, visual or tactile stimuli can modulate acoustically-driven activity. Here, the authors show that circuits linking the primary somatosensory cortex to both the auditory midbrain and thalamus allow tactile inputs to modulate

A physiologically inspired model for solving the cocktail party problem. [PDF]

, 2019
At a cocktail party, we can broadly monitor the entire acoustic scene to detect important cues (e.g., our names being called, or the fire alarm going off), or selectively listen to a target sound source (e.g., a conversation partner).

Ultrasound Modulation of Visual Circuits in Mice Independent of Auditory Confound

Advanced Science, EarlyView.
In this study, Qiu et al. found that low‐intensity ultrasound can directly activate sparse ultrasound‐sensitive neurons (UNs) in the primary visual cortex (V1) of deafened mice. The proportion of these sparse UNs is pressure‐dependent. Furthermore, ultrasound modulates visual circuitry with distinct excitatory and inhibitory effects.

Amplitude and frequency-modulated stimuli activate common regions of human auditory cortex [PDF]

, 2003
Hall et al. (Hall et al., 2002, Cerebral Cortex 12:140–149) recently showed that pulsed frequency-modulated tones generate considerably higher activation than their unmodulated counterparts in non-primary auditory regions immediately posterior and ...
