Sensation seeking correlates with increased white and grey matter integrity of structures associated with visuospatial and decision-making processing in healthy adults (original) (raw)

Background: The ability to process sensory information is an essential adaptive function, and hyper- or hypo-sensitive maladaptive profiles of repones to environmental stimuli generate sensory processing disorders linked to cognitive, affective, and behavioural alterations. The research on neuroradiological correlates of the sensory processing profiles is still in its infancy and is mainly limited to the young-age population or neurodevelopmental disorders. So, the knowledge concerning the impact of the different sensory profiles on the structural and functional characteristics of the typically developed adult brain remains largely obscure. In this framework, this study aims to examine the structural and functional MRI correlates of sensory profiles in a sample of healthy adults. Method: We investigated structural T1, Diffusion Tensor Imaging (DTI), and resting-state functional MRI (rs-fMRI) correlates of Adolescent/Adult Sensory Profile (AASP) questionnaire subscales in 57 typical ...
