Disentangling the Dopaminergic System

December 3, 2014 3:55 pm | News | Comments

Though dopamine neurons influence many diverse behaviors and diseases, scientists have historically presumed that all of these important nerve cells are molecularly similar within two clusters of the brain. In a new study, Northwestern Medicine scientists prove that premise wrong by identifying several molecularly distinct subtypes of dopamine neurons within each cluster. Read more...

Tiny Patient Prompts Advance in Neurogenetics

November 24, 2014 11:54 am | News | Comments

Researchers had never shown exactly how cells in the brain stem detect carbon dioxide and regulate breathing in humans. After taking a mutation from a two-month-old baby and expressing it in human astrocytes, they did exactly that, and the research may lead to an early warning system to save premature infants.

Exploring the Genomes of Mice and Men

November 20, 2014 10:15 am | News | Comments

For decades, the mouse has been a mainstay for researchers studying human diseases because the two species share many of the same genes. But now, a comprehensive analysis of the inner workings of the DNA in humans and mice has uncovered some striking differences in the way their genes are controlled.
