Researchers led by David W. Blodgett and Marek Mirski at Johns Hopkins developed a non-invasive, label-free optical technique to detect neural activity via tissue deformation in real time.
To validate optical signals, they used NeuroNexus HC-32-600-10-100 ECoG arrays and a SmartBox Pro data acquisition system to capture simultaneous electrical recordings from the rodent somatosensory cortex.
