Optogenetics without the genetics

March 12, 2015

Optogenetics, a technique which enables scientists to control the activity of neurons with light, has revolutionaized the field of neuroscience. However, it relies on genetic engineering, which limits its use. A new study demonstrates a potential solution to this problem: gold nanoparticles. [Read More]

A snapshot of neural activity

February 16, 2015

A new study authored by Ben Fosque, first year graduate student in biochemistry and molecular biology, describes how he and his mentors engineered a new fluorescent protein, activated by a flash of violet light, that permanently marks neurons that fire -- a literal snapshot of neural activity.

Low-frequency deep brain stimulation improves difficult-to-treat Parkinson’s symptoms

January 27, 2015

University of Chicago Medicine doctors, led by Tao Xie, MD, PhD, assistant professor of neurology, have shown that Parkinson’s disease patients who are treated with low-frequency deep brain stimulation show significant improvements in swallowing dysfunction and freezing of gait over typical high-frequency treatment. The study provides a new route for treating these difficult-to-treat and sometimes life-threatening symptoms. [Read More]
