F.lux: sleep research. Trouble sleeping?
If you have sleep trouble or you're trying to learn more about sleep in general, we recommend understandingsleep.org. Study: Reading on a tablet vs. book In 2014, a new study was published in PNAS (full text) that compares the effects of reading an iPad before bed, versus a regular paper book. AMA Report In 2012, the American Medical Association's Council on Science and Public Health made this recommendation: "Recognizes that exposure to excessive light at night, including extended use of various electronic media, can disrupt sleep or exacerbate sleep disorders, especially in children and adolescents.
Blue Light Affects Sleep (and here's why) We know that night-time exposure to blue light keeps people up late. To understand the effects of f.lux on sleep, we've spoken with some researchers, and we've read a whole lot of papers. Popular press coverage of blue light research Blue Light David C. Digital Health Oxford #2 - Digital Health Oxford (Headington, England. After a fantastic first meetup it's great to announce the second Digital Health Oxford event for early 2014. The format will be similar, with 3 short, informal talks, questions and drinks. The speakers at this event will be: • Dr Chris Hinds, lead software developer in the Dept. of Psychiatry, University of Oxford will talk about the TrueColours project he heads up "an online self-management system that allows you to monitor your symptoms and experiences using text, email and the internet.
" ( • Dave Fletcher, founder and managing director of Oxford-based White October, will talk about the myPace mobile app they developed in conjunction with Brunel University to help patients manage weight loss and improve the relationship between patient and dietician ( • Russell Brown, senior software engineer at Basho, who played a key role in their work on the NHS Spine II project in 2013. You need a holiday, says neuroscience. The Best Monitor Setup to Reduce Eye Fatigue and Distraction. For years I’ve struggled to find a monitor setup that allows me to be the most productive, without causing eye fatigue or eye strain.
Here’s my best answer so far: I now use a vertical monitor with high pixel density. It helps reduce eye fatigue, clicks, and distraction. Home - Health & Social Care Information Centre.

Diffusion MRI (or dMRI) is a magnetic resonance imaging (MRI) method which came into existence in the mid-1980s.[1][2][3] It allows the mapping of the diffusion process of molecules, mainly water, in biological tissues, in vivo and non-invasively.
Molecular diffusion in tissues is not free, but reflects interactions with many obstacles, such as macromolecules, fibers, membranes, etc. Water molecule diffusion patterns can therefore reveal microscopic details about tissue architecture, either normal or in a diseased state. The first diffusion MRI images of the normal and diseased brain were made public in 1985.[4][5] Since then, diffusion MRI, also referred to as diffusion tensor imaging or DTI (see section below) has been extraordinarily successful.
Its main clinical application has been in the study and treatment of neurological disorders, especially for the management of patients with acute stroke. Diffusion[edit] Given the concentration and flux where D is the diffusion coefficient. . Registration Theory - reg.pdf. Functional magnetic resonance imaging. Researcher checking fMRI images Functional magnetic resonance imaging or functional MRI (fMRI) is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting associated changes in blood flow.[1] This technique relies on the fact that cerebral blood flow and neuronal activation are coupled.
When an area of the brain is in use, blood flow to that region also increases. The primary form of fMRI uses the Blood-oxygen-level dependent (BOLD) contrast,[2] discovered by Seiji Ogawa. The procedure is similar to MRI but uses the change in magnetization between oxygen-rich and oxygen-poor blood as its basic measure. This measure is frequently corrupted by noise from various sources and hence statistical procedures are used to extract the underlying signal.
FMRI is used both in the research world, and to a lesser extent, in the clinical world. Magnetic resonance imaging. Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is a medical imaging technique used in radiology to investigate the anatomy and function of the body in both health and disease.
MRI scanners use strong magnetic fields and radiowaves to form images of the body. The technique is widely used in hospitals for medical diagnosis, staging of disease and for follow-up without exposure to ionizing radiation. Introduction[edit] Neuroimaging[edit] MRI image of white matter tracts. MRI is the investigative tool of choice for neurological cancers as it is more sensitive than CT for small tumors and offers better visualization of the posterior fossa. How to Prevent an Acidic Stomach from Drinking Coffee. Do you get an acidic stomach when you drink a cup of coffee?
Many coffee-lovers do, and some won't give up their daily cup of Joe despite their burning stomach. Fortunately, there may be some relief in sight for people who get stomach irritation from drinking coffee.
