vertex waves definition
The present study investigated the localization of the. vertex waves. Vertex waves are spike-shaped wave-. forms seen in the EEG leads located in the superior. parietal area during late stage 1 and stage 2 sleep. [1,10]. Vertex waves are thought to have numerous. generators [6] and possibly are secondary evoked po-.
Adjacency matrix (vertex matrix) Graphs can be very complicated. We can associate a matrix with each graph storing some of the information about the graph in that matrix. This matrix can be used to obtain more detailed information about the graph. If a graph has vertices, we may associate an matrix which is called vertex matrix or adjacency matrix.
