How to capture videos of brains in real time http://ift.tt/2sTaUgJ Individual neurons firing within a volume of brain tissue (credit: The Rockefeller University) A team of scientists has peered into a mouse brain with light, capturing live neural activity of hundreds of individual neurons in a 3D section of tissue at video speed (30 Hz) in a single recording for the first time. Besides serving as a powerful research tool, this discovery means it may now be possible to “alter stimuli in real time based on what we see going on in the animal’s brain,” said Rockefeller University’s Alipasha Vaziri , senior author of an open-access paper published June 26, 2017 in Nature Methods . By dramatically reducing the time and computational resources required to generate such an image, the algorithm opens the door to more sophisticated experiments, says Vaziri, head of the Rockefeller Laboratory of Neurotechnology and Biophysics . “Our goal is to better understand brain function by monitor...

Inequalities in malaria research funding in sub-Saharan Africa

Inequalities in malaria research funding in sub-Saharan Africa http://ift.tt/2tZzF9s A quarter of countries in sub-Saharan Africa receive very little funding for research into malaria despite having high malaria-related death rates. In a new study, led by the University of Southampton and published in The Lancet Global Health , countries have been ranked according to how much research and non-research funding they receive from major public and philanthropic global health funders to combat the disease. The study examined the portfolios of several of the major global health research funders and compared funding levels to national malaria-related burden of disease. They could not find any investment for malaria research in countries such as Sierra Leone, Mauritania, Chad, Congo and Central African Republic. Chad, Congo and Central African Republic are among the countries with the highest malaria death rates in the world at 71.9, 64.84 and 128.34 per 100,000 of the population resp...
