Abstract
Various systems and methods for predicting occurrence of a neurological event are disclosed. In certain embodiments, a neurological event detection system may comprise a sensor configured to be placed in the body of a patient, the sensor comprising a plurality of electrodes, at least one of the electrodes being configured to detect neurological signals emanating from a portion of the brain of the patient over a plurality of time periods. The system may also include a signal analyzer configured to analyze the signals to determine a number of spikes detected by each electrode during each time period. The system may also detect a number of instances where spikes associated with at least two neurons are detected at substantially the same time during each time period, and determine a correlation between the number of spikes and the number of instances for each time period.
