Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

open access: yesAdvanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Cirsoid Aneurysm of the Scalp: A Case Report

open access: yesIndian Journal of Neurosurgery, 2016
Cirsoid aneurysms (arteriovenous malformations [AVMs]) of the scalp are rarely encountered in neurosurgical practice. Patients with AVM of the scalp present clinically at times with headache and a small innocuous-looking subcutaneous scalp lump or a ...

On the monotonicity of scalar curvature in classical and quantum information geometry

open access: yes, 2004
We study the statistical monotonicity of the scalar curvature for the alpha-geometries on the simplex of probability vectors. From the results obtained and from numerical data we are led to some conjectures about quantum alpha-geometries and Wigner ...

Review of recent progress toward a fiberless, whole-scalp diffuse optical tomography system

open access: yesNeurophotonics, 2017
. The development of a whole-scalp, high sampling-density diffuse optical tomography (DOT) system is a critical next step in the evolution of the field of diffuse optics. To achieve this with optical fiber bundles is extremely challenging, simply because

Delayed Transplantation of Neural Stem Cells Improves Initial Graft Survival after Stroke

open access: yesAdvanced Science, EarlyView.
Delayed transplantation of human iPSC‐derived neural progenitor cells (NPCs) enhances graft survival, proliferation, and axonal sprouting after stroke. Using bioluminescence imaging and histology in a mouse model of stroke, it is shown that NPC delivery at 7 days post‐stroke is more effective than acute transplantation, highlighting the importance of ...

Definitive cranioplasty and scalp reconstruction in recurrent dermato fibrosarcoma protuberance of scalp

open access: yesIndian Journal of Neurosurgery, 2013
Dermatofibrosarcoma protuberans (DFSP) of the scalp is a relatively uncommon soft-tissue neoplasm. Calvarial involvement can lead to a quick intracranial spread making the tumor incurable.

Through Skull Fluorescence Imaging of the Brain in a New Near-Infrared Window

open access: yes, 2014
To date, brain imaging has largely relied on X-ray computed tomography and magnetic resonance angiography with limited spatial resolution and long scanning times.
