Abstract
The authors examine the causal structure of neural recordings from fruit flies in the context of distinguishing wakefulness and general anesthesia. They find that distinguishability is improved by considering higher orders of non-Markovian temporal correlations in the neural signals, and that the wakeful neural signals exhibit a greater degree of temporal asymmetry compared to under anesthesia
