Catching calcium waves could provide Alzheimer's insights
Date:2/12/2010

Today's fMRI (functional magnetic resonance imaging) tools are useful for studying the brain, but their spatial resolution is far too course to provide insights at the cellular level. "With fMRI, you have no information on what is happening at the individual circuit and network level," said Silva. With technologies such as two photon optical microscopy, researchers are aiming to uncover how the brain works in much finer detail.

Mapping Brain Networks is Just the Start

While mapping the activity of cell networks is "a fantastically interesting problem" according to Silva, it is just the beginning. A more difficult problem involves determining how the brain uses that information. "Pushing the envelope of understanding for these types of problems requires breakthroughs in engineering, math and physics. That is the interesting part for us," said Silva.
