Susan R. Barry
Susan R. Barry is a Professor Emeritus of Biological Sciences and Professor Emeritus of Neuroscience and Behavior at Mount Holyoke College and the author of two books, ''Fixing My Gaze: A Scientist's Journey into Seeing in Three Dimensions'' and ''Coming to Our Senses: A Boy Who Learned to See, A Girl Who Learned to Hear, and How We All Discover the World''. Barry was dubbed Stereo Sue by neurologist and author Oliver Sacks in a 2006 ''New Yorker'' article with that name. Barry's first book greatly expands on Sacks' article and discusses the experience of gaining stereovision through optometric vision therapy, after a lifetime of being stereoblind. It challenges the conventional wisdom that the brain is wired for perceptual skills during a critical period in early childhood and provides evidence instead for neuronal plasticity throughout life. Barry's achievement of stereo vision, with the help of a developmental optometrist Theresa Ruggiero, was reported in a BBC ''Imagine'' ...

HONORIFIC
An honorific is a title that conveys esteem, courtesy, or respect for position or rank when used in addressing or referring to a person. Sometimes, the term "honorific" is used in a more specific sense to refer to an honorary academic title. It is also often conflated with systems of honorific speech in linguistics, which are grammatical or morphological ways of encoding the relative social status of speakers. Honorifics can be used as prefixes or suffixes depending on the appropriate occasion and presentation in accordance with style and customs. Typically, honorifics are used as a style in the grammatical third person, and as a form of address in the second person. Use in the first person, by the honored dignitary, is uncommon or considered very rude and egotistical. Some languages have anti-honorific (''despective'' or ''humilific'') first person forms (expressions such as "your most humble servant" or "this unworthy person") whose effect is to enhance the relative honor a ...

Stereopsis Recovery
Stereopsis recovery, also recovery from stereoblindness, is the phenomenon of a stereoblind person gaining partial or full ability of stereo vision (stereopsis). Recovering stereo vision as far as possible has long been established as an approach to the therapeutic treatment of stereoblind patients. Treatment aims to recover stereo vision in very young children, as well as in patients who had acquired but lost their ability for stereopsis due to a medical condition. In contrast, this aim has normally not been present in the treatment of those who missed out on learning stereopsis during their first few years of life. In fact, the acquisition of binocular and stereo vision was long thought to be impossible unless the person acquired this skill during a critical period in infancy and early childhood. This hypothesis normally went unquestioned and has formed the basis for the therapeutic approaches to binocular disorders for decades. It has been put in doubt in recent years. In partic ...

Ralph Siegel (scientist)
Ralph Mitchell Siegel, a researcher who studied the neurological underpinnings of vision, was a professor of neuroscience at Rutgers University, Newark, in the Center for Molecular and Behavioral Neuroscience. He died September 2, 2011, at his home following a long illness. Siegel, a neurophysiologist, was interested in the basic mechanisms underlying visual motion and spatial perception, with the ultimate goal of developing applications to assist people who have visual processing disorders and neurological injuries. He performed pioneering work on parietal neurons and the influence of eye position and attention on perception. His laboratory became the first to perform optical imaging of parietal cortex in behaving non-human primates. Biography Siegel earned his B.S. in physics and his Ph.D. in physiology from McGill University in Montreal. Ralph's 1984 Ph.D. thesis in the lab of Richard I. Birks revealed astonishingly large and long-lasting potassium conductance and sodium pump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bob Wasserman
Robert "Bob" Wasserman (January 12, 1934 – December 29, 2011) was an American politician and retired police chief, who served as the Mayor of Fremont, California, from 2004 to 2011. He has been credited with integrating Fremont's economy and workforce with into the larger Silicon Valley during his tenures as mayor and a city councilman. Biography Early life Wasserman was born in Gary, Indiana, on January 12, 1934, to Morris and Alice Wasserman. He moved with his family to Los Angeles when he was three years old, and attended schools in the city. Wasserman served in the U.S. Army National Guard in 1949 when he was just 16 years old. He falsely told the army recruiter that he was 18 years old at the time of his enlistment. He was honorably discharged in 1952 after serving in the Korean War. Following his discharge, Wasserman joined the California National Guard, where he served as a military police inspector and rose to the rank of sergeant first class. Wasserman continued his ...

Stereopsis
Stereopsis () is the component of depth perception retrieved through binocular vision. Stereopsis is not the only contributor to depth perception, but it is a major one. Binocular vision happens because each eye receives a different image because they are in slightly different positions on one’s head (left and right eyes). These positional differences are referred to as "horizontal disparities" or, more generally, " binocular disparities". Disparities are processed in the visual cortex of the brain to yield depth perception. While binocular disparities are naturally present when viewing a real three-dimensional scene with two eyes, they can also be simulated by artificially presenting two different images separately to each eye using a method called stereoscopy. The perception of depth in such cases is also referred to as "stereoscopic depth". The perception of depth and three-dimensional structure is, however, possible with information visible from one eye alone, such as diffe ...

Brock String
A Brock string (named after Frederick W. Brock) is an instrument used in vision therapy. It consists of a white string of approximately 10 feet in length with three small wooden beads of different colors. The Brock string is commonly employed during treatment of convergence insufficiency and other anomalies of binocular vision. It is used to develop skills of convergence as well as to disrupt suppression of one of the eyes. During therapy, the one end of the Brock string is held on the tip of the nose while the other is tied to a fixed point. The three beads are spaced out at various distances. The patient is asked to focus on one of the beads, while noting the visual input of each eye and sensation of convergence. The patient can use variable techniques to make easier or more difficult by bringing the beads closer\further to the nose and by employing lenses and prisms. Although this procedure is usually associated with binocular vision and anti-suppression therapy, it can also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fixation (visual)
Fixation or visual fixation is the maintaining of the gaze on a single location. An animal can exhibit visual fixation if it possess a fovea in the anatomy of their eye. The fovea is typically located at the center of the retina and is the point of clearest vision. The species in which fixational eye movement has been verified thus far include humans, primates, cats, rabbits, turtles, salamanders, and owls. Regular eye movement alternates between saccades and visual fixations, the notable exception being in smooth pursuit, controlled by a different neural substrate that appears to have developed for hunting prey. The term "fixation" can either be used to refer to the point in time and space of focus or the act of fixating. Fixation, in the act of fixating, is the point between any two saccades, during which the eyes are relatively stationary and virtually all visual input occurs. In the absence of retinal jitter, a laboratory condition known as retinal stabilization, perceptions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strabismus Surgery
Strabismus surgery (also: ''extraocular muscle surgery'', ''eye muscle surgery'', or ''eye alignment surgery'') is surgery on the extraocular muscles to correct strabismus, the misalignment of the eyes. Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ophthalmologist. The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return home. History The earliest successful strabismus surgery intervention is known to have been performed on 26 October 1839 by Johann Friedrich Dieffenbach on a 7-year-old esotropic child; a few earlier attempts had been performed in 1818 by William Gibson of Baltimore, a general surgeon and professor at the University of Maryland. The idea of treating strabismus by cutting some of the extraocular muscle fibers was published in American newspapers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Esotropia
Esotropia is a form of strabismus in which one or both eyes turns inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. It is the opposite of exotropia and usually involves more severe axis deviation than esophoria. Esotropia is sometimes erroneously called "lazy eye", which describes the condition of amblyopia; a reduction in vision of one or both eyes that is not the result of any pathology of the eye and cannot be resolved by the use of corrective lenses. Amblyopia can, however, arise as a result of esotropia occurring in childhood: In order to relieve symptoms of diplopia or double vision, the child's brain will ignore or "suppress" the image from the esotropic eye, which when allowed to continue untreated will lead to the development of amblyopia. Treatment options for esotropia include glasses to correct refractive errors (see accommodative esotropia below), the use of prisms and/or orthopti ...

Astronaut
An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a human spaceflight program to serve as a commander or crew member aboard a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear. In China, the People's Liberation Army Astronaut Corps astronauts and their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
