Specially tailored, ultrafast pulses of light can trigger neurons to fire and could one day help patients with light-sensitive circadian or mood problems, according to a new study in mice at the University of Illinois. Chemists have used such carefully crafted light beams, called coherent control, to regulate chemical reactions, but this study is the first demonstration of using them to control function in a living cell. The study used optogenetic mouse neurons – that is, cells that had a gene added to make them respond to light.
A new study by University of Illinois researchers found that monounsaturated fatty acids – a class of nutrients found in olive oils, nuts and avocados – are linked to general intelligence, and that this relationship is driven by the correlation between MUFAs and the organization of the brain’s attention network.
Neuroscience graduate student Sara Schmidt, and speech and hearing science professor Fatima Husain conducted a study that found that tinnitus patients have differences in the region of the brain called the precuneus, which cause the brain to stay more at attention and be less at rest.
New research by human development and family studies professor Karen Kramer and doctoral researcher Sunjin Pak found that men’s and women’s psychological well-being is affected differently when their wages and share of their family’s income changes.
