“…The finding that the RH auditory cortex can support speech perception aligns with reports of high-level language processing being successfully supported by the right hemisphere in some individuals with early left-hemisphere damage (Newport et al, 2022; Tuckute et al, 2022; see François et al, 2021 for a review). Such individuals develop linguistic abilities at the same time as their neurotypical peers and exhibit no language difficulties as adults.…”

Human cortical responses to natural sounds, measured with fMRI, can be approximated as the weighted sum of a small number of canonical response patterns (components), each having interpretable functional and anatomical properties. Here, we asked whether this organization is preserved in cases where only one temporal lobe is available due to early brain damage by investigating a unique family: one sibling born without a left temporal lobe, another without a right temporal lobe, and a third anatomically neurotypical. We analyzed fMRI responses to diverse natural sounds within the intact hemispheres of these individuals and compared them to 12 neurotypical participants. All siblings manifested the neurotypical auditory responses in their intact hemispheres. These results suggest that the development of the auditory cortex in each hemisphere does not depend on the existence of the other hemisphere, highlighting the redundancy and equipotentiality of the bilateral auditory system.

“…The injury of arcuate fiber bundles in specific functional language areas of the brain is the main factor leading to aphasia after stroke, which can also be used as an imaging auxiliary tool to evaluate the patient's condition [ 37 ]. François C. [ 38 ] found that patients with Broca aphasia, Wernicke aphasia, and conductive aphasia had different degrees of damage to the arcuate fiber bundle, and the damage location was related to the type of aphasia: Patients with Broca aphasia mainly had damage and displacement of the integrity of the front end of the arcuate fiber bundle, and patients with Wernicke aphasia mainly had middle and rear damage. In patients with conductive aphasia, the central part of the arcuate fiber bundle on the functional side was mainly damaged.…”

Aphasia after stroke is one of the common complications of cerebral infarction. Early diagnosis and treatment of aphasia after stroke is of great significance for the recovery of language function. At present, there are different views on the pathogenesis of aphasia after stroke. Functional magnetic resonance imaging (fMRI) can reflect the brain function, brain tissue metabolism, and the level of brain local blood flow. It has the advantages of noninvasive, high resolution and sensitivity, low price, and so on. It has been widely used in the study of sensory aphasia after stroke. This study focuses on the development of functional magnetic resonance imaging in patients with poststroke aphasia and summarizes the published studies on functional magnetic resonance imaging in patients with poststroke aphasia. Evidence acquisition: A literature search was conducted in PubMed, Hindawi, PLoS, IEEE, Wiley, ScienceDirect, Springer, EMBASE, and web of science, with the keywords of “stroke” and “Aphasia” and “functional magnetic resonance imaging”, “RS fMRI”, or “DTI”, to review the research of functional magnetic resonance imaging in patients with aphasia after stroke. The results included clinical evaluation, diagnostic scale, and imaging analysis; the study design was a randomized controlled trial, case series and case report, and observational study. A total of 67 articles were identified in the first search and 43 after the second search. Based on the analysis of 43 selected articles, 19 articles were included, and 24 articles were excluded. The selected information is shown in Table 1. Eleven of them did not contain imaging-related data. Six articles are related review articles. Four studies were conducted on patients without poststroke aphasia. Three studies studied the effect of poststroke aphasia on patients’ social participation.

“…These may occur 24 h a day, making it difficult to distinguish foreground from background sounds at 60 db or to filter out and process noxious stimuli [36][37][38]. In this environment, the preterm infant is being deprived of the exposure to the human voice and speech, which is associated with the neurobiology of language development [39][40][41][42][43][44][45][46][47][48][49].…”

The Soundscape of Neonatal Intensive Care: A Mixed-Methods Study of the Parents’ Experience

et al. 2021

Parents who have infants hospitalised in neonatal intensive care units (NICUs) experience high levels of stress, including post-traumatic stress disorder (PTSD) symptoms. However, whether sounds contribute to parents’ stress remains largely unknown. Critically, researchers lack a comprehensive instrument to investigate the relationship between sounds in NICUs and parental stress. To address this gap, this report presents the “Soundscape of NICU Questionnaire” (SON-Q), which was developed specifically to capture parents’ perceptions and beliefs about the impact that sound had on them and their infants, from pre-birth throughout the NICU stay and in the first postdischarge period. Parents of children born preterm (n = 386) completed the SON-Q and the Perinatal PTSD Questionnaire (PPQ). Principal Component Analysis identifying underlying dimensions comprising the parental experience of the NICU soundscape was followed by an exploration of the relationships between subscales of the SON-Q and the PPQ. Moderation analysis was carried out to further elucidate relationships between variables. Finally, thematic analysis was employed to analyse one memory of sounds in NICU open question. The results highlight systematic associations between aspects of the NICU soundscape and parental stress/trauma. The findings underscore the importance of developing specific studies in this area and devising interventions to best support parents’ mental health, which could in turn support infants’ developmental outcomes.
