Leveraging Input-Level Feature Deformation with Guided-Attention for Sulcal Labeling.

The identification of cortical sulci is key for understanding functional and structural development of the cortex. While large, consistent sulci (or primary/secondary sulci) receive significant attention in most studies, the exploration of smaller and more variable sulci (or putative tertiary sulci) remains relatively under-investigated. Despite its importance, automatic labeling of cortical sulci is challenging due to (1) the presence of substantial anatomical variability, (2) the relatively small size of the regions of interest (ROIs) compared to unlabeled regions, and (3) the scarcity of annotated labels.

Lateral frontoparietal functional connectivity based on individual sulcal morphology.

Unlabelled: A salient neuroanatomical feature of the human brain is its pronounced cortical folding, and there is mounting evidence that sulcal morphology is relevant to functional brain architecture and cognition. Recent studies have emphasized putative tertiary sulci (pTS): small, shallow, late-developing, and evolutionarily new sulci that have been posited to serve as functional landmarks in association cortices. A fruitful approach to characterizing brain architecture has been to delineate regions based on transitions in fMRI-based functional connectivity profiles; however, exact regional boundaries can change depending on the data used to generate the parcellation.

Perceived Impacts of Partners' Other Relationships on Oneself in Consensual Nonmonogamy.

Existing research suggests a number of both costs and benefits to oneself that can occur as a result of partners' other relationships in consensual nonmonogamy (CNM), but such costs and benefits have not previously been systematically cataloged. Using reflexive thematic analysis, we present themes derived from semi-structured interviews with 51 individuals (63% white, 55% nonbinary/genderqueer/non-cisgendered, and 77% LGBQ) who have practiced CNM, describing the costs and benefits to themselves that they perceive as a result of their partners' other relationships. Themes describing costs include experiencing difficult feelings (e.

Sulcal variability in anterior lateral prefrontal cortex contributes to variability in reasoning performance among young adults.

Identifying structure-function correspondences is a major goal among biologists, cognitive neuroscientists, and brain mappers. Recent studies have identified relationships between performance on cognitive tasks and the presence or absence of small, shallow indentations, or sulci, of the human brain. Building on the previous finding that the presence of the ventral para-intermediate frontal sulcus (pimfs-v) in the left anterior lateral prefrontal cortex (aLPFC) was related to reasoning task performance in children and adolescents, we tested whether this relationship extended to a different sample, age group, and reasoning task.

Neuroanatomical and Functional Dissociations between Variably Present Anterior Lateral Prefrontal Sulci.

The lateral prefrontal cortex (LPFC) is an evolutionarily expanded region in humans that is critical for numerous complex functions, many of which are largely hominoid specific. Although recent work shows that the presence or absence of specific sulci in anterior LPFC is associated with cognitive performance across age groups, it is unknown whether the presence of these structures relates to individual differences in the functional organization of LPFC. To fill this gap in knowledge, we leveraged multimodal neuroimaging data from two samples encompassing 82 young adult humans (aged 22-36 years) and show that the dorsal and ventral components of the paraintermediate frontal sulcus, or pimfs, present distinct morphological (surface area), architectural (thickness and myelination), and functional (resting-state connectivity networks) properties.
