Adaptation of the steady-state PERG in early glaucoma

, 2014
Previous studies have shown that the onset of high-contrast, fast reversing patterned stimuli induces rapid blood flow increase in retinal vessels in association with slow changes of the steady-state pattern electroretinogram (PERG) signal. We tested the

Retinal biomarkers in cognitive impairment and dementia: Structural, functional, and molecular insights

Alzheimer's &Dementia, Volume 21, Issue 9, September 2025.
Abstract Cognitive impairment and dementia, including Alzheimer's disease (AD), pose a global health crisis, necessitating non‐invasive biomarkers for early detection. This review highlights the retina, an accessible extension of the central nervous system (CNS), as a window to cerebral pathology through structural, functional, and molecular ...

Retinal vascular dysfunction in the Mthfr677C>T mouse model of cerebrovascular disease

Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract INTRODUCTION Investigations of retinal biomarkers for Alzheimer's disease (AD) and AD and related dementias (ADRD), has increased significantly. We examine retinal vascular health in a mouse containing the ADRD risk variant Mthfr677C>T to determine if changes in retina mirror similar changes in cerebrovasculature.

From Neurotransmission to Retinal Pathophysiology: Unraveling the Role of GABA Receptors in Retinal Disease Progression

Journal of Neurochemistry, Volume 169, Issue 8, August 2025.
GABA receptors, widely expressed in the retina, play a key role in lateral inhibition and synaptic regulation. Emerging evidence links their dysregulation to retinal diseases such as diabetic retinopathy, retinitis pigmentosa, glaucoma, and age‐related macular degeneration.

Splitting the penalty by taking turns? Same‐sex mothers' earnings losses in Norway

Journal of Marriage and Family, Volume 87, Issue 4, Page 1524-1548, August 2025.
Abstract Objective This study describes the childbearing trajectories and earnings of mothers in female same‐sex couples (FSSC) in Norway and, through comparisons with mothers in different‐sex couples (DSC), explores three factors behind mothers' earnings losses. Background Mothers in FSSC experience smaller earnings penalties following parenthood than
