Schizophrenia patients with auditory verbal hallucinations (AVH) frequently exhibit brain structural alterations, particularly reductions in gray matter volume (GMV).Understanding the neurobiological mechanisms underlying the changes is essential for advancing treatment strategies. To address this, a meta-analysis was conducted to identify GMV changes in schizophrenia patients with AVH and their associations with gene expression and neurotransmitter receptor profiles.

Emotions are expressed via many features including facial displays, vocal intonation, and touch, and perceivers can often interpret emotional displays across the different modalities with high accuracy. Here, we examine how emotion perception from faces and voices relates to one another, probing individual differences in emotion recognition abilities across visual and auditory modalities. We developed a novel emotion sorting task, in which participants were tasked with freely grouping different stimuli into perceived emotional categories, without requiring pre-defined emotion labels.

Acoustic amplitude modulation (AM) patterns carry important information, particularly in speech. AM masking, influenced by frequency selectivity in the modulation domain, is considered a crucial factor for speech intelligibility in noisy environments. Based on recent evidence suggesting an age-related decline in AM frequency selectivity, this study investigated whether increased AM masking in older listeners is associated with reduced speech intelligibility.

Objective: In children with bilateral cochlear implants(CIs): 1) quantify cortical access and sensitivity to inter-aural level differences(ILDs); 2) determine if cortical ILD detection predicts ILD perception; and 3) assess demographic and clinical factors that could limit ILD access.
Methods: Cortical detection responses evoked by ILD changes were measured in 22/24 children with bilateral CIs(7 female) using their clinically programmed devices and in 8 children(3 female) with normal hearing. Behavioral lateralization(left vs right perception) to ILDs was also measured.

To navigate real-world listening conditions, the auditory system relies on the integration of multiple sources of information. However, to avoid inappropriate cross-talk between inputs, highly connected neural systems need to strike a balance between integration and segregation. Here, we develop a novel approach to examine how repeated neurochemical modules in the mouse inferior colliculus lateral cortex (LC) allow controlled integration of its multimodal inputs.
