Fig. 1. (A) The MSA contributions (Shapley value) for a test case are compared with the contributions yielded by single lesion analysis and with the FCA contributions (mean and standard deviations across 10 FCA runs using the full set of all 2⁴ multi-lesions). All three values are normalized such that the sum over all elements equals 1. (B) MSA contributions, FCA contributions and predicted MSA contributions of the EAA's neurons. All are based on the full set of 2¹⁰ multi-lesions and are normalized such that the sum of the contributions of all the neurons equals 1.

Fig. 2. Agent performance as a function of pruning level, by MSA and by FCA. In both methods the synapses are incrementally lesioned by ascending order of their contribution. The figure focuses on the first 80 synapses pruned, where the agent has still viable performance.

Fig. 3. Two-dimensional MSA of reversible deactivation experiments. (A) Predicted MSA contributions of the eight regions. Regions 6 and 8 represent SC_R-deep and SC_L-deep, respectively. (B) The symmetric interaction between each pair of regions.
