To Visualize Neurons of the Deep Brain for Months at a Time
Stanford researchers have developed a new technique that allows them to monitor the tiny branches of neurons in a live brain for months at a time. Neuroscientists will now be able to monitor the microscopic changes that occur over the course of progressive brain disease.
Travel just one millimeter inside the brain and you'll be stepping into the dark.
Standard light microscopes don't allow researchers to look into the interior of the living brain, where memories are formed and diseases such as dementia and cancer can take their toll.
But Stanford scientists have devised a new method that not only lets them peer deep inside the brain to examine its neurons but also allows them to continue monitoring for months.
The technique promises to improve understanding of both the normal biology and diseased states of this hidden tissue.
Other recent advances in micro-optics had enabled scientists to take a peek at cells of the deep brain, but their observations captured only a momentary snapshot of the microscopic changes that occur over months and years with aging and illness.
The Stanford development appeared online Jan. 16 in the journal Nature Medicine. It also will appear in the February 2011 print edition.
