Stimulation becomes insufficient for cortical measurements of acuity when pixel size falls below 55 μm in rats12, and perceptual measurements of acuity below 75 μm in humans13. Fig. 2: Electric field with various implant geometries overlaid on retinal histology. Electric field above the ...
Salamanders have the amazing ability to regrow lost limbs. When a salamander limb is amputated, cells at the injury site regroup and begin a regeneration process that reforms the entire limb. Interestingly, scientists today are working to helphumans regenerate body parts. History of Surgical Amputat...
Slam Jam, Ill-Studio and General_Index present the Attention Deficit Disorder Prosthetic Memory Program. A perspective on the cultural and cognitive flattening of human networked recollections through a series of encyclopedic explorations.
The effect of pupil diameter on MTF. Image quality is known to decrease with pupil size in humans16 as well as in rodent17. To study the effect of pupil diameter on the MTF we ran ZEMAX simulations for pupil diame- ters ranging from 0.2 mm to 3.2 mm for both visible (525...
In the drawings, the letter S designates generally a prosthetic vision system according to the present invention for assisting vision-impaired or blind users in seeing. Although principally intended for use with humans, the present invention might as well be used in animals, particularly in experimen...
He was taken to a rehab facility in Omaha, where it was determined that he had severe eye dysfunction, and was blind in both eyes.He lived there for many months learning how to navigate in a world of darkness, and even made friends with a young female fox. Yet, when it came time ...
It took ten years for her landmine-inflicted wound to heal, but since then she, too, has received various versions of her prosthesis. A 2012 documentary, "The Eyes of Thailand," chronicles both Mosha and Motala's journeys and experiences in what is known as the world's first elephant hosp...
the unimpaired subjects spend the majority of the time looking at the plasticine. The inference from this is that the user of a prosthesis needs to monitor the prosthesis and the objects equally, moving their eyes away from the task to the hand and back, checking that the prosthesis is still...
considered as a relevant model to isolate the effect of the stiffness. Eleven subjects wearing prosthetic feet with different modules were asked to remain as static as possible both with open eyes (OE) and closed eyes (CE). The center of pressure (COP) displacements and the joint angles ...
