By David Ivanov, Biochemistry and Molecular Biology, 2015 LASIK, or laser-assisted in situ keratomileusis, is a surgical procedure commonly used to correct for visual defects or lack of visual clarity. Commonly referred to as laser eye surgery, LASIK is a type of surgery that is used to alleviate visual loss associated with common defects of the eye, such as myopia (nearsightedness), hypermetropia (farsightedness), and astigmatism. Astigmatism, like near and far-sightedness, can be caused by the irregularity in shape of the cornea that leads to blurred vision. For all three cases, corneal remodeling via LASIK can be performed (Thomson, 2015). The cornea is the outermost layer of the eye, the transparent part that one can touch, and upon which contact lenses […]
By: Jenny Cade, Biochemistry & Molecular Biology ‘15 One of the biggest challenges in neuroscience today is mapping the wiring of the nervous system. Looking at the spatial arrangement of neural networks can tell us a lot about how information is relayed, but accurate 3D mapping of neurons is an enormously challenging task, even with the aid of computer analysis. One group of researchers at MIT has harnessed the power of crowdsourcing to tackle this problem.
