Neuroscientists have sought to better understand brain function but lacked the capability to observe neuronal activity deep within the brain.
EMBL scientists applied rational molecular engineering to develop photoacoustic probes that can be used deep within brain tissue to label and track firing of individual neurons.
This imaging approach expands significantly on what neuroscientists have been able to see with conventional light microscopy, offering the potential to report on deep neuron activity and better understand brain function.
This research represents a first proof of principle for a dynamic observation tool that could significantly improve our understanding of brain function.
