Abstract
This document discloses, among other things, ictal source analysis and causal interaction estimation which considers the structure of seizures in the space, time, and frequency domains. The dynamic causal interaction can distinguish the primary source, which initiates the ictal activity, from the secondary source, which is generated due to the ictal activity propagation.

43. A system comprising:
-
an interface configured to receive epileptiform data from a brain; a memory to store a model for the brain; and a processor coupled to the memory and to the interface, the memory having instructions stored thereon for executing an algorithm to determine a solution using the epileptiform data and the model, the solution including identification of a plurality of sources, an estimate of spatio-temporal distribution for the plurality of sources, and including an estimate of connectivity for at least two sources of the plurality of sources. - View Dependent Claims (44, 45, 46, 47)

48. A method comprising:
-
receiving data corresponding to spatio-temporal cortical electrical potential distribution, the data including a plurality of interictal spikes; calculating latencies between interictal spikes; and determining a cortical neuronal activation sequence using the latencies. - View Dependent Claims (49, 50, 51, 52)
