Identifying sources and sinks in the interictal iEEG network. (A) An N-channel iEEG network example. (B) Signals obtained from the implanted iEEG channels. (C) Corresponding A matrix, estimated from the signals in B. (D) 2D source-sink representation of the iEEG network with sink index (sink_i), source influence (infl_i) and sink connectivity (conn_i) labelled. In this space, sources are channels located at the top left (blue circles), whereas sinks (pink circles) are located at the bottom right. Blue star = ideal source; pink star = ideal sink.
