"mathematical strategy of tracking correlated activity among the neurons during the delay period. By determining which neurons were working together and cohesively to perform the task, he could determine their connectivity and therefore the information flow among them. From there, using standard principles of biophysics, he calculated the electric field their activity was producing around the patches of brain surface they occupied"
