The increase in green fluorescence, right, shows the imaging of protein
synthesis at synapses when memories are made.


Method:

The researchers used a fluorescent protein that can change from green to red
when exposed to ultraviolet light. They flashed the cells with light, so
that any proteins that already existed turned red. But when the scientists
induced the cells to form memories, they saw new green proteins appear under
the microscope.

"One distinction between short-term and long-term memory is this requirement
for making new proteins," said co-investigator Wayne Sossin, a
neuroscientist at McGill University in Montreal. "To make it last, you do
need protein synthesis."

The study, conducted by researchers at the Montreal Neurological Institute
and Hospital (The Neuro), McGill University and University of California,
Los Angeles.

我非常支持LTM需要新蛋白合成的观念.

各位高手讨论一下, GFP 到RFP的UV处理转换的效率有多高, 可不可能REVERSE?这个方法追踪新生蛋白是不是足够严格?

这个方法足够严格的话, 以后的用处就很多了
