The state transition diagram and attractor cycles of the inferred gene regulatory network. A square node stands for a transient state; a round one, an attractor. Inside each node, a sequence of numbers indicates the state of all genes that node represents. A directed edge from a source to a destination node suggests that the state represented by the source node evolves into the state by the destination node. The red color encodes the states under the influence of alcohol; the blue color saline (control).
