Photoactivated molecules for light-induced modulation of the activity of electrically excitable cells and methods of using same

Robert H. Chow, +7 more
TL;DR: In this paper, methods and compositions for the modulation of the activity of electrically excitable cells are presented. But they do not consider the use of photovoltaic compounds which, upon exposure to light energy, increase or decrease the electrical activity of cells.
Proceedings ArticleDOI

Transcranial Focused Ultrasound for Non-invasive Neuromodulation of the Visual Cortex

Gengxi Lu, +9 more
TL;DR: The results showed that blind rats showed more robust responses to ultrasound stimulation compared to normal rats, and inferred that acoustic radiation force (ARF) is the predominant physical mechanism of ultrasound neuromodulation.
Proceedings ArticleDOI

Surface modification of neural stimulating/recording microelectrodes with high-performance platinum-pillar coatings

Kai Xia, +4 more
TL;DR: Investigation of the structure, morphology and electrochemical properties of the electrodeposited Pt-pillar coatings revealed good mechanical stability as well as electrochemical stability, which is highly preferred for effective neural stimulation and recording in various applications.
Journal ArticleDOI

Hyperspectral imaging of retinal microvascular anatomy

Amir H. Kashani, +5 more
TL;DR: A hyperspectral computed tomographic imaging spectroscope that provides high spatial, spectral and temporal resolution ideal for imaging biological tissue in vivo and allows for reliable and reproducible tissue classification and detection using signature discriminant analysis is described.
Proceedings ArticleDOI

Wireless Implantable Intraocular Pressure Sensor with Parylene-Oil-Encapsulation and Forward-Angled RF Coil

Aubrey Shapero, +5 more
TL;DR: In this article, the authors presented a wireless and implantable intraocular pressure (IOP) sensor with parylene-oil-encapsulation packaging using a novel folded PCB architecture accomplishing practical RF coupling for power and data in a rabbit.
