NIH Scientists Develop Novel Technique to Study Brain Disease
A new tool developed by researchers at the National Institutes of Health has determined, for the first time, how two distinct sets of neurons in the mouse brain work together to control movement. The method, called spectrally resolved fiber photometry (SRFP), can be used to measure the activity of these neuron groups in both healthy mice and those with brain disease. The scientists plan to use the technique to better understand what goes wrong in neurological disorders, such as Parkinson’s disease (PD).
According to Guohong Cui, M.D., Ph.D., head of the In Vivo Neurobiology Group at the National Institute of Environmental Health Sciences (NIEHS), part of NIH, the project began because he wanted to find out why patients with PD have problems with movement. Typically, PD motor symptoms include tremor, muscle stiffness, slowness of movement, and impaired balance.
