Caption
Orange-arrow loop: Intracranial electrophysiological data are captured by macro-microelectrodes from the subject’s brain and streamed to the data acquisition device and a host computer, where the data analysis is performed. In the host computer, real-time high-pass filtering and spike sorting are conducted, which provides real-time single-neuron activity. After a fast analysis of the neurons’ responses, the responsive stimuli are selected and maintained in the stimulus set presented to the subject. Blue-arrow loop: The intracranial electrophysiology data are collected with the data acquisition device and processed by the host computer, where biomarkers of memory functioning are extracted to drive electrical stimulation to enhance memory performance.
