To investigate the contribution of sleep duration and quality to age-related changes in brain structure cognitive performance relatively healthy older adults. Community-based longitudinal aging study using a convenience sample. Participants were studied research laboratory. Relatively adults aged 55 y at commencement. N/A. underwent magnetic resonance imaging neuropsychological assessment every 2 y. Subjective assessments blood samples obtained. Each hour reduced baseline augmented annual...
Media multitasking, or the concurrent consumption of multiple media forms, is increasingly prevalent in today's society and has been associated with negative psychosocial cognitive impacts. Individuals who engage heavier media-multitasking are found to perform worse on control tasks exhibit more socio-emotional difficulties. However, neural processes multi-tasking remain unexplored. The present study investigated relationships between multitasking activity brain structure. Research...
Neuroimaging non-human primates (NHPs) is a growing, yet highly specialized field of neuroscience. Resources that were primarily developed for human neuroimaging often need to be significantly adapted use with NHPs or other animals, which has led an abundance custom, in-house solutions. In recent years, the global NHP community made significant efforts transform towards more open and collaborative practices. Here we present PRIMatE Resource Exchange (PRIME-RE), new online platform...
In the primate brain, a set of areas in ventrolateral frontal (VLF) cortex and dorsomedial (DMF) appear to control vocalizations. The basic role this network human brain how it may have evolved enable complex speech remain unknown. present functional neuroimaging study multidomain protocol was utilized investigate roles various that comprise VLF–DMF learning rule-based cognitive selections between different types motor actions: manual, orofacial, nonspeech vocal, vocal actions. Ventrolateral...
Human sleep schedules vary widely across countries. We investigated whether these variations were related to differences in social factors, Morningness-Eveningness (ME) preference, or the natural light-dark cycle by contrasting duration and timing of young adults (age: 18-35 years) on work free days Singapore (n = 1898) UK 837). On days, people had later bedtimes, but wake times similar sample, resulting shorter duration. In contrast, did not differ between two Shorter without compensatory...
According to contemporary views, the lateral frontal cortex is organized along a rostro-caudal functional axis with increasingly complex cognitive/behavioral control implemented rostrally, and detailed motor caudally. Whether medial follows same organization remains be elucidated. To address this issue, connectivity of 3 cingulate areas (CMAs) in human brain was investigated. First, CMAs their representations hand, tongue, eye movements were mapped via task-related magnetic resonance imaging...
Brain mapping studies often need to identify brain structures or functional circuits into a set of individual brains. To this end, multiple atlases have been published represent such based on different modalities, subject sets, and techniques. The mainstream approach exploit these consists in spatially deforming each data onto given atlas using dense deformation fields, which supposes the existence continuous between individuals. However, continuity is not always verified, "iconic" has...
Abstract The inferior frontal sulcus ( ifs ) is a prominent on the lateral cortex, separating middle gyrus from gyrus. morphology of can be difficult to distinguish adjacent sulci, which are often misidentified as continuations . morphological variability and its relationship surrounding sulci were examined in 40 healthy human subjects (i.e., 80 hemispheres). identified labeled native cortical surface meshes individual subjects, permitting proper intra‐sulcal assessment. Two main patterns...
The ability to solve problems creatively is a vital educational outcome. Here we pursued the hypothesis that media multitasking (MM), which becoming increasingly prevalent in modern learning contexts, may be positively associated with creative performance. One hundred and four participants completed questionnaire three well-established creativity tasks: (1) Alternate Uses Task (AUT), (2) modified version of Remotes Associates (RAT) and, finally, (3) Creative Achievement Questionnaire (CAQ)....
Group level analyses of functional regions involved in voice perception show evidence 3 sets bilateral voice-sensitive activations the human prefrontal cortex, named anterior, middle and posterior Frontal Voice Areas (FVAs). However, relationship with underlying sulcal anatomy, highly variable this region, is still unknown. We examined inter-individual variability FVAs conjunction anatomy. To do so, anatomical MRI scans from 74 subjects were analyzed to generate individual contrast maps...
Carnivorans are an important study object for comparative neuroscience, as they exhibit a wide range of behaviours, ecological adaptations, and social structures. Previous studies have mainly examined relative brain size, but comprehensive understanding diversity requires the investigation other aspects their neuroanatomy. Here, we obtained primarily post-mortem scans from eighteen species order Carnivora, reconstructed cortical surfaces, neocortical sulcal anatomy to establish framework...
Abstract Speech error monitoring recruits the medial frontal cortex (MFC) region in human brain. Error monitoring-related activity MFC has been interpreted both terms of conflict and feedback-driven control, but as similar regions are implicated various levels behavioral control ranging from basic motor movement to high-level cognitive functions, a more comprehensive account is needed. Moreover, speech errors other actions that involve varying demands engage widespread yet partially...

Internet technologies have profoundly changed the way we access information, manage our tasks, consume media, and social interactions. The present work aims to provide insights into long-term, causal influence of exposure on cognitive systems via an unprecedented, intervention-based experiment where investigated potential brain changes that occurred in a rare sample 35 young Indian adults who had minimal prior contact with Internet-related technologies, after being provided unlimited for...
