Abstract The cavum septi pellucidi (CSP), a persistent separation between the septal leaflets in the brain, is found among athletes exposed to repetitive head impacts (RHI), yet existing grading systems may inadequately capture anatomical variants. This study presents a revised CSP grading scale for RHI-exposed populations. This cross-sectional study included 170 former American football players and 54 unexposed asymptomatic controls, all males aged 45-74, who underwent magnetic resonance imaging.
Abstract Research in humans and animal models suggests that visual responses in early visual cortical areas may be modulated by top-down influences from distant cortical areas, particularly in the frontal and parietal regions. The right posterior parietal cortex is part of a broad cortical network involved in aspects of visual search and attention, but its role in modulating activity in early visual cortical areas is less well understood.
