The human eyes encompass incredible natural abilities, including an exceptionally wide field of view, and high resolution married with low distortion capabilities, almost impossible to synthetically recreate in their entirety. … Continue Reading World’s first spherical artificial eye with 3D retina developed.
In a crucial partnership, brain function relies on the central nervous system’s primary cell, the neuron, connecting with other neurons to form a circuit known as a synapse to produce … Continue Reading The brain combines artificial and natural vision to restore sight.
A natural inbuilt timer, the circadian rhythm is a 24-hour cycle in all humans, plants, and animals determining sleep and feeding patterns. Circadian rhythms are endogenously generated and can be … Continue Reading The skin keeps time independently of the brain.
When a person looks at an object, each eye sees it from a slightly different angle and sends those binocular-based pictures back to the brain. The differences between the two … Continue Reading Neurons responsible for 3D vision identified.
The purpose of blinks is to keep the eyes hydrated and to protect them. Blinks are rarely noticed by the subject as blink-induced alterations of visual input are blanked out … Continue Reading Researchers identify a new eye movement in human studies.
While some things may be ‘as simple as black and white,’ this has not been the case for the circuits in the brain that make it possible for a person … Continue Reading Study visualises, maps cortical circuits that encode black and white for the first time.
Degeneration of the white matter of the brain may be an early marker of specific types of Alzheimer’s disease (AD), including early-onset AD, according to results of a new study … Continue Reading Researchers identify specific types of Alzheimer’s disease using white matter neuroimaging test.
Certain vision-impaired individuals have the ability to use echoes from tongue or finger clicks to recognize objects in the distance, and some use echolocation as a replacement for vision. Research from … Continue Reading Study shows that human vision-impaired ‘echolocators’ can substitute echolocation for vision.
Reporting on their study with lab-grown human cells, researchers at The Johns Hopkins University and the University of Maryland say that blocking a second blood vessel growth protein, along with … Continue Reading Researchers identify new protein responsible for diabetes-associated blindness.
There is widespread belief in the scientific community that dyslexia, which affects around 375,000 UK children and has a lifelong impact on learning, is not caused by sight problems. However, … Continue Reading Children with dyslexia found to have ‘normal vision’.
Previous studies have shown that the connection in the adult brain are hard to change, while in children, novel experiences rapidly mold new connections during critical periods of brain development. … Continue Reading Researchers reactivate juvenile neural plasticity in adult brains.
Live Ebola virus can persist within the eyes for months after a patient recovers from acute Ebola viral disease (EVD), according to a case report from researchers at Emory University. … Continue Reading Ebola virus can persist for months within survivors’ eyes.
A new study from scientists at The Scripps Research Institute (TSRI) shows that nerve cells and blood vessels in the eye constantly talk to each other to maintain healthy blood … Continue Reading Study finds nerve cells and blood vessels in eye ‘talk’ to prevent disease.
An interdisciplinary team of researchers from the University of Rochester has used a new imaging technique to show how the human brain heals itself in just a few weeks following … Continue Reading Researchers develop new neuroimaging technique to measure myelin insulation, brain repair.
Researchers from École polytechnique fédérale de Lausanne (EPFL) have participated in the development of a contact lens for the early detection of glaucoma. Clinical trials are being conducted at the … Continue Reading An innovative smart contact lens for glaucoma.
