A pilot study with the families of three participants informed the adaptations for the main study, which was implemented with the families of nine participants. The research was conducted using an Embedded Mixed Methods Design, a distinctive approach that allowed for a comprehensive understanding of the outcomes. The primary research design was a single-subject research model with multiple probes across participants' designs, ensuring a thorough and individualized assessment. The study was carried out in both home and clinical settings, involving the participation of special education teachers and families. The findings indicate that the tact and mand-modeling procedures presented through the CBC method significantly improved the children's communication skills and led to substantial reductions in tantrum behaviors. All families indicated that the dependent variables held significant social importance. Significant enhancements were noted in the children's communication skills and social engagements after the intervention. The CBC intervention was determined to be feasible and feasible for families, with no additional expenses accrued. The long-term suitability and usefulness of the product in many environments increased its societal acceptance.

In this study, we conducted a meticulous integrative review across Medline, Scopus, and LILACS databases, targeting investigations utilizing fNIRS to explore language-related features and cortical activation during auditory stimuli in typical infants. We included studies that used the NIRS technique to study language and cortical activation in response to auditory stimuli in typical infants between 0 and 3 years old. We used the ROBINS-I tool to assess the quality and the risk of bias in the studies. Our analysis, encompassing 66 manuscripts, is presented in standardized tables for streamlined data extraction. We meticulously correlated findings with children's developmental stages, delineating crucial insights into brain development and its intricate interplay with language outcomes. Although most studies have a high risk for overall bias, especially due to the high loss of data in NIRS studies, the low risk in the other domains is predominant and homogeneous among the studies. Highlighted are the unique advantages of fNIRS for pediatric studies, underscored by its innate suitability for use in children. This review accentuates fNIRS' capacity to elucidate the neural correlates of language processing and the sequential steps of language acquisition. From birth, infants exhibit abilities that lay the foundation for language development. The progression from diffuse to specific neural activation patterns is extremely influenced by exposure to languages, social interaction, and prosodic features and, reflects the maturation of brain networks involved in language processing. In conclusion, fNIRS emerges as an indispensable functional imaging modality, providing insights into the temporal dynamics of language acquisition and associated developmental milestones. This synthesis presents the pivotal role of fNIRS in advancing our comprehension of early language development and paves the way for future research endeavors in this domain.</p>","PeriodicalId":13914,"journal":{"name":"International Journal of Developmental Neuroscience","volume":"84 7","pages":"613-637"},"PeriodicalIF":1.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141971089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hippocampal neurogenesis has been suggested to play a role in learning and memory. Neurokinin 3 receptor (NK3R) has been shown to be prevalent in the hippocampus region. The aim of the project was to investigate the role of hippocampal neurogenesis in the promnestic effects of NK3R agonist administration in an amyloid beta-induced AD rat model. Wistar albino rats were divided into control, Alzheimer, NK3R agonist and Alzheimer + NK3R agonist groups. The open field (OF) test and Morris water maze (MWM) test were performed for locomotor activity and memory analysis. Peptide gene expression levels (Nestin, DCX, Neuritin, MASH1, Neun, BDNF) were analysed by quantitative reverse transcription polymerase chain reaction (RT-PCR). In the OF test, the group–time relationship was found to be statistically different in the parameters of distance travelled and percentage of movement (<i>p</i> &lt; 0.05). In MWM, the time to reach the platform and the time spent in the target quadrant were statistically significant between the groups (<i>p</i> &lt; 0.05).

It was concluded that NK3 receptor agonism in the hippocampus, which is the first affected region in the physiopathology of AD, may be effective in both the formation of neural precursor cells and the reduction of neuronal degeneration.

In the present study, maternal approach towards a vocalizing pup over a non-vocalizing pup was tested in a Y-maze apparatus at two developmental time points over the course of MS. At postnatal day (P)10, MS dams engaged in longer interaction times with vocalizing pups compared to non-vocalizing pup, and this effect was strongest in male pups. As expected at P20, dams did not show a preference for either the vocalizing or non-vocalizing pups regardless of rearing environment; however, MS dams spent a greater amount of time in the center of the apparatus as compared to control dams, which can be interpreted as a measure of uncertainty or indecision. These effects of MS on dam USV sensitivity are important considering the sex specific effects of MS exposure across all developmental stages.
