Before revision:   Our results suggest that whether or not transfer entropy measures of causality are misleading depends strongly on the cognitive task considered.
After revision:  We also test whether activity time-series recorded from behaving digital brains can infer information flow using the transfer entropy concept, when compared to a ground-truth model of causal influence constructed from connectivity and circuit logic. Our results suggest that whether or not transfer entropy measures of causality are misleading depends strongly on the cognitive task considered.
