Researchers Investigating New Treatment for Multiple Sclerosis

A new treatment under investigation for multiple sclerosis (MS) is safe and tolerable in phase 1 clinical trials, according to a study published August 27, 2014, in Neurology® Neuroimmunology & Neuroinflammation, a new online-only, freely accessible, specialty medical journal. The publication is part of the Neurology® family of journals, published by the American Academy of Neurology.

Changing the Emotional Association of Memories

By manipulating neural circuits in the brain of mice, scientists have altered the emotional associations of specific memories. The research, led by Howard Hughes Medical Institute investigator Susumu Tonegawa at the Massachusetts Institute of Technology (MIT), reveals that the connections between the part of the brain that stores contextual information about an experience and the part of the brain that stores the emotional memory of that experience are malleable.

Scientists at The Scripps Research Institute solved the mystery of why a specific signaling pathway can be associated with alcohol dependence. The new research shows the gene, Nf1, regulates gamma-aminobutyric acid (GABA), a neurotransmitter that lowers anxiety and increases relaxation feelings.

EPO May Help Reduce Risk of Brain Abnormalities in Preterm Infants

High-dose erythropoietin (EPO; a hormone) administered within 42 hours of birth to preterm infants was associated with a reduced risk of brain injury, as indicated by magnetic resonance imaging, according to a study in the August 27 issue of JAMA.
