Experimental data obtained with these methods, along with a more exact knowledge of the anatomy (asphericities) of the optical surfaces of the eye, permit us to build more accurate models of the optical system of the eye, learn about its wide-angle optical design, and develop applications....
COLUMBUS, Ohio, Sept. 19, 2013 — A new lens that combines the focusing ability of the human eye with an insect's wide-angle view could help make a confocal microscope with no moving parts, or improve surgical imaging. "Our eye can change focus. An insect eye is made of many smallopt...
Furthermore, such a wide angle would appear highly distorted and unnatural if it were captured by a camera.Left Eye Dual Eye Overlap Right EyeOur central angle of view — around 40-60° — is what most impacts our perception. Subjectively, this would correspond with the angle over which ...
"There are types of brain damage where you can't see something move, or where you can't recognize faces — you'll look and pick out an eye or a nose or mouth, instead of the whole face," Singman says. The brain, in fact, can perform tricks to make up for the eyes' shortcomings...
The visual axis is a nodal ray19 of the eye that intersects the fovea. The angle α is the angle between the visual axis of the eye and the optical axis12. The visual axis is generally displaced nasally and superiorly within the visual field relative to the optical axis. The horizontal ...
Ocular coloboma has been reported in up to 11.2% of blind children worldwide, with an estimated incidence of between 0.5–7.5 per 10 000 births and is often associated with other congenital anomalies of the eye.17 Mutations in PAX2, CHD7, SOX2, PAX6, GDF6, YAP1 OTX2, SHH, SIX3, ...
Perception is often modelled as a process of active inference, whereby prior expectations are combined with noisy sensory measurements to estimate the structure of the world. This mathematical framework has proven critical to understanding perception, co
The trabecular meshwork’s (TM) physiological role is to maintain normal intraocular pressure by regulating aqueous humor outflow. With age, and particularly in eyes with primary open angle glaucoma, the number of cells residing within the TM is markedly
Here, we proposed a simple neural circuit model that can address these challenges in a wide range of timing tasks. The model is comprised of two modules, an MPM that generates timed actions, and a SAM that predicts the time of upcoming external events. Both modules were engineered to ...
Despite a century of research, it remains unclear whether human intelligence should be studied as one dominant, several major, or many distinct abilities, and how such abilities relate to the functional organisation of the brain. Here, we combine ps
