Retinal and post-retinal contributions to the quantum efficiency of the human eye revealed by electrical neuroimaging

The retina is one of the best known quantum detectors with rods able to reliably respond to single photons. However, estimates on the number of photons eliciting conscious perception, based on signal detection theory, are systematically above these values ...

Modeling dynamic aspects of human nonvisual responses to light

Marilyne Andersen, María Lovísa Ámundadóttir, Steven W. Lockley

Since 2002, when the first reports on the discovery of a novel type of mammalian ocular photoreceptor were published, a new field of study at the intersection of photobiology and architecture started to emerge. These novel non-rod, non-cone photoreceptors ...

Depletion-interaction effects on the tunneling conductivity of nanorod suspensions

Peter Ryser, Claudio Grimaldi, Biagio Nigro

We study by simulation and theory how the addition of insulating spherical particles affects the conductivity of fluids of conducting rods, modeled by spherocylinders. The electrical connections are implemented as tunneling processes, leading to a more det ...

Healthy lighting: integrating non-visual responses into simulation framework

María Lovísa Ámundadóttir

Lighting is one of the most significant factors in the built environment that affect human health and wellbeing. In addition to stimulating visual responses, light induces a range of non-visual responses in humans including synchronizing circadian rhythms ...

A polymer-based interface restores light sensitivity in rat blind retinas

Diego Ghezzi

Purpose: Sight restoration is one of the new frontiers for prosthetic devices that enable the electrical stimulation of neurons. In particular, diseases that affect the retinal pigment epithelium and photoreceptors but preserve the inner retinal layers are ...

Long-term in vivo impedance changes of subretinal microelectrodes implanted in dystrophic P23H rats

Philippe Renaud, Olof Pontus Linderholm

Retinal prostheses are being developed to restore vision in blind patients with photoreceptor degeneration. Electrodes arrays were subretinally implanted in transgenic P23H rats with their photoreceptors degenerated. Electrical stability of the implants wa ...
