cesses. In particular this approach may be useful for spike train analysis and for the
investigation of the relations between point processes and continuous signals.
4.1.7.3.7 Statistical assessment of time-varying connectivity Functional con-

taken into account when constructing the statistical tool to test the significance of the
changes in the connectivity related to an event. Especially, it is difficult to keep the
assumption that during the longer baseline epoch the connectivity is stationary. ERC
