Optical brain function imaging
WebFast optical imaging, and in particular the event-related optical signal (EROS, a technology that has emerged over the last 15 years) may provide descriptions of localized (to sub-cm level) brain activity with a temporal resolution of less than 100 ms. WebIntroduction. An optic disk pit is a congenital abnormality of the optic nerve head, first described in 1882 by Wiethe 1 as a gray, white–yellow, or black round depression in the optic disk. 2 Optic disk pits are extremely rare, with an incidence of one in 11,000. 3 In 1927, Halbertsma 4 described an association of optic disk pit with macular lesions and poor …
