Abstract: The invention provides an assembly comprising: a recording assembly for recording a time-based brain-related signal; a stimulus generator for providing a stimulus, and a computer assembly, functionally coupled to said recording assembly and to said stimulus generator, said computer assembly comprising: a memory for storing at least a data segment of said time-based brain-related signal during recording of said time-based brain-related signal, and a computer program which, when running on said computer assembly, functionally real-time performs: retrieving a most-recent data segment of said stored data segment of said time-based brain-related signal; fitting at least one curve to said retrieved most-recent data segment; predicting a future continuation of said most-recent data segment using said at least one curve fitted to said most-recent data segment; detecting a predefined pattern in said predicted future continuation for predicting occurrence of said predefined pattern, and defining a predicted event time
