Abstract Dissociative experiences commonly occur alongside adverse childhood (ACE), yet research on their neurofunctional biomarkers has overlooked unique association with dimensions of abuse and neglect. We investigated interactions between dissociative abuse, anticipating anti-correlations the right-lateralized anterior middle frontal gyrus (raMFG) medial temporal lobe, as well gyri. Examining resting-state functional connectivity in 91 participants a history ACE, we employed seed-to-voxel...

Background: Post-traumatic stress disorder (PTSD) is increasingly prevalent in individuals with adverse childhood experiences (ACE). However, the underlying neurobiology of ACE-related PTSD remains unclear.

The human cerebellum is involved in a wide array of functions, ranging from motor control to cognitive control, and as such great neuroscientific interest. However, its function underexplored vivo, due small size, dense structure placement at the bottom brain, where transmit receive fields are suboptimal. In this study, we combined two coil arrays 16 surface elements each with three antenna improve BOLD sensitivity 7 T. Our results showed improved B 1 + SNR close well g ‐factor gains...

Early childhood neglect can impact brain development across the lifespan. Using voxel-based approaches we recently reported that severe and time-limited institutional deprivation in early was linked to substantial reductions total volume adulthood, >20 years later. Here, extend this analysis explore deprivation-related regional white matter microstructural organization using diffusion-based techniques. A combination of tensor-based morphometry (TBM) tractography conducted on...

Adverse childhood experiences (ACE) are well-known risk factors for the development of PTSD later in life. The overall effect ACE on WM integrity and moderation this relation still being researched. Using a total 78 participants with any form ACE, we show that was negatively correlated genu body corpus callosum bilateral uncinated fasciculus after controlling psychological burden. strength changed when added as moderator variable.

This paper focuses on the significance of multimodal affective computing techniques in improving human-robot interaction. The remote measurement vital signals, such as heart rate, through deep learning has paved way for more accessible and natural interaction with robots. However, to enable successful interactions users who may be unfamiliar robots, robust interactive user interfaces are crucial. study emphasizes importance combining different modalities human-computer create a comprehensive...

Adverse childhood experiences (ACE), which can be separated into abuse and neglect, contribute to the development of post-traumatic stress symptoms (PTSS). However, brain structures are mainly affected by ACE as well mediating role these play in PTSS relationship still being investigated. The current study tested effect on structure investigated latter's ACE-PTSS relationship. A total 78 adults with self-reported were included this study. Participants completed trauma questionnaire (CTQ) a...
