A subretinal implant is advantageous over an epiretinal implant in part because of its simpler design. The light acquisition, processing, and stimulation are all carried out by microphotodiodes mounted onto a single chip, as opposed to the external camera, processing chip, and implanted electrode array associated with an epiretinal implant.

neuroretinal rim (area and volume) and peripapillary retinal nerve fiber layer (retinal surface height variation, thickness, asymmetry). These stereometric parameters are compared with extensive databases and thus enable the eye to be classified taking into account the individual papillae size and the patient's age.
For those who became deaf pre-lingually, cross modal plasticity interfered with their ability to process language using a cochlear implant. For the pre-lingual deaf, the auditory cortex has been reshaped to deal with visual information, so it cannot deal as well with the new sensory input that the implant provides.
FDA inspectors identified the issues at Neuralink's animal testing facilities in California in June 2023, several weeks after the agency had given the company the green light for a small study of ...
Notch-mediated juxtacrine signal between adjacent cells Notch signaling steps. The Notch signaling pathway is a highly conserved cell signaling system present in most animals. [1] Mammals possess four different notch receptors, referred to as NOTCH1, NOTCH2, NOTCH3, and NOTCH4. [2] The notch receptor is a single-pass transmembrane receptor protein.
Two people have been arrested and are facing charges of felony child abuse after a one-month-old baby was discovered in the median of a road Christmas morning.
National Park officials urged caution after a toddler nearly fell off a 400-foot cliff while the family visited erupting volcano Kīlauea. After a three-month pause the Kilauea Volcano in Hawaii ...
The elder sibling and the mother were found to have severe hearing loss which heavily diminished their ability at recognizing speech, while the younger brother was relatively okay at doing so. All three individuals were found to have ocular scotomas (also known as blind spot) and neuroretinal rim loss. They were the only affected people with ...
