This grew out of research studies that demonstrated a change in the timing and firing pattern of various muscles between groups of people with and without back pain. (drbradcole.com)
Since the pulses of light exert highly precise control over the neurons, it opens the possibility of very selective studies of firing patterns in brain regions of interest. (aaas.org)
Data on neural firing patterns were recorded while the monkey was performing this task. (quantamagazine.org)
