Abstract: Statistical effects of cortical metrics derived from standard T1‐ and T2‐weighted magnetic resonance imaging (MRI) images, such as gray–white matter contrast (GWC), boundary sharpness coefficient (BSC), T1‐weighted/T2‐weighted ratio (T1w/T2w), and cortical thickness (CT), are often… read more here.

Abstract: Delay discounting (DD) refers to a phenomenon that humans tend to choose small-sooner over large-later rewards during intertemporal choices. Steep discounting of delayed outcome is related to a variety of maladaptive behaviors and is considered… read more here.

DOI: 10.1093/cercor/bhad052
Abstract: Age-related changes of intracortical myelin in bipolar disorder (BD) have been observed to deviate from the quadratic age curve observed in healthy controls (HC), but it is unclear if this holds at varying cortical depths.… read more here.

DOI: 10.1111/acps.12875
Abstract: Although cognitive dysfunction persists through affective and euthymic states in bipolar disorder (BD), its neurobiological correlates remain undetermined. We explore whole‐cortex intracortical myelin (ICM) and cognition in BD‐I and controls. read more here.

DOI: 10.1111/bdi.13181
Abstract: OBJECTIVE Psychosocial functioning in bipolar disorder (BD) persists even during euthymia and has repeatedly been associated with illness progression and cognitive function. Its neurobiological correlates remain largely unexplored. Using a structural covariance approach, we explored… read more here.

DOI: 10.3389/fnagi.2022.896848
Abstract: Evidence suggests that lightly myelinated cortical regions are vulnerable to aging and Alzheimer’s disease (AD). However, it remains unknown whether plasma markers of amyloid and neurodegeneration are related to deficits in intracortical myelin content, and… read more here.
