Spontaneous slow cortical potentials and brain oscillations independently influence conscious visual perception.
PLoS Biol
January 2025
Neuroscience Institute, New York University Grossman School of Medicine, New York, New York, United States of America.
Perceptual awareness results from an intricate interaction between external sensory input and the brain's spontaneous activity. Pre-stimulus ongoing activity influencing conscious perception includes both brain oscillations in the alpha (7 to 14 Hz) and beta (14 to 30 Hz) frequency ranges and aperiodic activity in the slow cortical potential (SCP, <5 Hz) range. However, whether brain oscillations and SCPs independently influence conscious perception or do so through shared mechanisms remains unknown.

Kikuchi-Fujimoto disease associated optic neuropathy in an adolescent.
Am J Ophthalmol Case Rep
March 2025
Department of Ophthalmology, Edward S. Harkness Eye Institute, Columbia University Irving Medical Center, New York Presbyterian Hospital, New York, NY, USA.
Purpose: We present a case of Kikuchi-Fujimoto Disease (KFD) associated with bilateral optic neuropathy progressing to vision loss.
Observations: A 17-year-old male was referred for bilateral optic nerve pallor. Eight years prior, he was diagnosed with KFD after workup for lymphadenopathy and treated with prednisolone acutely followed by long-term Plaquenil.
Use and Costs of Supplemental Benefits in Medicare Advantage, 2017-2021.
JAMA Netw Open
January 2025
Division of General Internal Medicine and Primary Care, Brigham and Women's Hospital, Boston, Massachusetts.
Importance: Nearly all Medicare Advantage (MA) plans offer dental, vision, and hearing benefits not covered by traditional Medicare (TM). However, little is known about MA enrollees' use of those benefits or how much they cost MA insurers or enrollees.
Objective: To estimate use, out-of-pocket (OOP) spending, and insurer payments for dental, hearing, and vision services among Medicare beneficiaries.
Characteristics, Risks, and Prevention of Rhegmatogenous Retinal Detachment in the Contralateral Eye.
J Clin Med
January 2025
Division of Ophthalmology, Department of Special Surgery, Faculty of Medicine, Jordan University of Science & Technology, Irbid 22110, Jordan.
: Rhegmatogenous retinal detachment (RRD) is a potentially blinding retinal disorder. RRD in the first eye is a well-recognized risk factor for bilateral RRD since risk factors that predispose to RRD affect both eyes. In this study, we assess the presenting factors that predispose individuals to bilateral RRD and evaluate the role of prophylactic retinopexy in preventing fellow-eye RRD.
