Fig. 2: Integrated information structure (IIS) for one channel set for one fly. left, Top-down view of the IIS. Mechanism size refers to the number of channels that constitute each mechanism (yellow, green, light blue, and dark blue dots indicate mechanisms consisting of 1, 2, 3, and 4 channels respectively). The y-axis is arbitrarily set to give equal spacing between mechanisms. Lines indicate inclusion relations (e.g., mechanism AB consists of A and B). middle, An exemplar IIS from a single fly and channel set, during wakefulness. right, An IIS from the same fly and channel set as in (middle) during anesthesia.
