Observation of cone and rod photoreceptors in normal subjects and patients using a new generation adaptive optics scanning laser ophthalmoscope. [PDF]

open access: yes, 2011
We demonstrate the capability of a new generation adaptive optics scanning laser ophthalmoscope (AOSLO) to resolve cones and rods in normal subjects, and confirm our findings by comparing cone and rod spacing with published histology measurements.

The Role of Scalp EEG Recordings During Cortical Visual Prosthesis Testing

open access: yesArtificial Organs, EarlyView.
This article describes the role of recording scalp EEG for projects that are developing cortical visual prosthesis systems. It concludes that EEG is not required during basic threshold and spatial mapping studies, but should be considered when higher levels of stimulation and video‐camera stimulation are employed.
