Now we can see brain cells 'talk' and that will shed light on neurological diseases

Scientists have developed a way to see brain cells talk -- to actually see neurons communicate in bright, vivid color. The new lab technique is set to provide long-needed answers about the brain and neurological diseases such as Alzheimer's disease, schizophrenia and depression. Those answers will facilitate new and vastly improved treatments for conditions that have largely resisted scientists' efforts to understand them.

"Before we didn't have any way to understand how [such neurotransmissions] work," said researcher J. Julius Zhu, PhD, of the University of Virginia School of Medicine. "In the case of Alzheimer's, in particular, we spent billions of dollars and we have almost no effective treatment. ... Now, for the first time, we can see what is happening."
