Scientists find a role for Parkinson’s gene in the brain

NIH-funded mouse study suggests LRRK gene is needed for dopamine neuron health. A new study published in the journal Neuron sheds light on the normal function of LRRK2, the most common genetic cause for late-onset Parkinson’s disease. The study was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.

Study shows how memories ripple through the brain

NIH-funded study suggests increased communication between key brain areas during sleep. Using an innovative “NeuroGrid” technology, scientists showed that sleep boosts communication between two brain regions whose connection is critical for the formation of memories. The work, published in Science, was partially funded by the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, a project of the National Institutes of Health devoted to accelerating the development of new approaches to probing the workings of the brain.
