Studying ACh In Rats

Alan McStravick for redOrbit.com — Your Universe Online Ivan Pavlov, a Russian physiologist, was instrumental in the formation of the school of study of conditioned response. His work, spanning some 40 years, has pervaded the public consciousness ever since. We are all, in one way or another, unwitting participants in his research. For instance, who among us doesn´t jump up to grab our mobile phone when it dings at us, signaling an incoming text message or e-mail?...

New research in Nature concludes the eye — which depends on light to see — also needs light to develop normally during pregnancy. Scientists say the unexpected finding offers a new basic understanding of fetal eye development and ocular diseases caused by vascular disorders — in particular one called retinopathy of prematurity that can blind premature infants. The research, led by scientists at Cincinnati Children's Hospital Medical Center and the University of...

Glaucoma Research Points To Potential Early Indicator
2013-01-02 13:21:05

Lee Rannals for redOrbit.com - Your Universe Online A new study has found that certain changes in blood vessels in the eye's retina can be an early sign that a person may have an increased risk of glaucoma. Researchers wrote in the journal Ophthalmology that they found that patients who have abnormally narrow retinal arteries are more likely to develop glaucoma 10 years down the road. The research could eventually provide ophthalmologists with a new tool to identify and treat those...

Scientists have developed a quick, easy and cheap vision test to find out which part — and how much — of the brain of a stroke victim has been damaged, potentially enabling them to save more lives. The test requires patients to look into a device for about ten minutes, enabling it to be used in the early stages of a stroke — even if the patient cannot move their limbs or speak. This can help doctors diagnose and treat the stroke quickly and accurately, which is vital,...

Dragonflies Show Human-like Selective Attention
2012-12-21 05:48:24

[ Watch the Video: Dragonfly on the Hunt ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Adelaide have uncovered the first evidence that invertebrates, like primates, have brain cells dedicated to the process of selective attention. Writing in the journal Current Biology, Dr. Steven Wiederman and associate professor David O'Carroll from the university's Centre for Neuroscience Research describe how they were able to learn that...

San Francisco, CA, Dec. 15-19, 2012 Moscone Center, 747 Howard Street ORGANIZING THE EYE'S NEURONS Poster: 2342/B1205 Special Interest Subgroup: Tissue Development and Morphogenesis II Tuesday, Dec. 18, 2012; Exhibit Halls A-C, 12:30 — 2 p.m. Authors: A. R. Tomás and M. R. Deans Tomás and Deans have identified a protein needed for neuron organization in the developing retina. The team says that the study helps reveal how the healthy retina...

Visual Sensitivity Improved By Learning To Control Brain Activity
2012-12-05 15:46:31

Wellcome Trust Training human volunteers to control their own brain activity in precise areas of the brain can enhance fundamental aspects of their visual sensitivity, according to a new study. This non-invasive 'neurofeedback' approach could one day be used to improve brain function in patients with abnormal patterns of activity, for example stroke patients. Researchers at the Wellcome Trust Centre for Neuroimaging at UCL used non-invasive, real-time brain imaging that enabled...

Study Finds As We Age, Our Reading Skills Tend To Change
2012-11-26 14:06:40

Lee Rannals for redOrbit.com — Your Universe Online According to research published in the journal Psychology and Aging, word recognition patterns can change as we grow older. University of Leicester psychologists carried out a study into eye-movements of young and old people to examine reading styles in the different age groups. The team discovered for the first time that the way we read words changes the older we get. Researchers conducted experiments that used precise...

Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
