The neuroanatomical correlates of attentive listening were investigated with functional magnetic resonance imaging and an attention task in which listeners responded only to words that combined two specific attributes of voice and semantic content. This task was performed under two different attentive listening conditions: (i) diotically, with words presented sequentially, and (ii) dichotically, with male and female voices presented simultaneously but segregated to different ears. For both conditions, functional magnetic resonance imaging revealed bihemispheric but right-lateralized activity patterns in mid-prefrontal, anterior cingulate, and inferior parietal areas, as well as significant anterior insular and subcortical activation. Manipulating attentional demands under different listening conditions revealed an important role for right anterior insula, striatum, and thalamus in the regulation of attentive listening to spoken language.

Musical interactions between caregivers and their infants typically rely on a limited repertoire of live vocal songs and recorded music. Research suggests that these well-known songs are especially effective at eliciting engaged behaviors from infants in controlled settings, but how infants respond to familiar music with their caregivers in their everyday environment remains unclear. The current study used an online questionnaire to quantify how often and why caregivers present certain songs and musical recordings to their infants.

The brain attends to environmental rhythms by aligning the phase of internal oscillations. However, the factors underlying fluctuations in the strength of this phase entrainment remain largely unknown. In the present study we examined whether the strength of low-frequency EEG phase entrainment to rhythmic stimulus sequences varied with pupil size and posterior alpha-band power, thought to reflect arousal level and excitability of posterior cortical brain areas, respectively.

The assessment of vascular accessibility in patients undergoing hemodialysis is predominantly reliant on manual inspection, a method that is associated with several limitations. In this study, we propose an alternative approach by recording the acoustic signals produced by the arteriovenous fistula (AVF) and employing deep learning techniques to analyze these sounds as an objective complement to traditional AVF evaluation methods. Auscultation sounds were collected from 800 patients, with each recording lasting between 24 and 30 s.

This study investigates the acquisition of sentence focus in Russian by adult English-Russian bilinguals, while paying special attention to the relative contribution of constituent order and prosodic expression. It aims to understand how these factors influence perceived word-level prominence and focus assignment during listening. We present results of two listening tasks designed to examine the influence of pitch cues and constituent order on perceived word prominence (Experiment 1) and focus assignment (Experiment 2) during the auditory comprehension of SV[O] and OV[S] sentences in Russian.

Purpose: This study aimed to assess the magnitude and direction of dual-task interference in a listening effort dual-task paradigm in individuals with severe-to-profound hearing loss before and in the short- and long-term after cochlear implantation.
Design: The study sample consisted of 26 adult candidates for cochlear implantation with severe-to-profound hearing loss. The dual-task paradigm consisted of a primary speech understanding task, conducted in a quiet condition, and a favorable and unfavorable noise condition on the one hand and a secondary visual memory task on the other hand.
