Behavioral performance, model fittings, and premotor neural activities during the target-holding period in the wood experiment. (A) Overview of the task-performing platform showing the wood arm. (B) The ownership illusion score in both arm and wood conditions in the human questionnaire experiment. (C) Spatial drifts in the V arm and wood conditions. (D and E) BCI model fitting in the wood and arm conditions and plots of the prior (Pprior) and the index of posterior common source probabilities (Pcom) (defined in Fig. 2J) in both humans (n = 17 participants) and monkeys (n = 69 sessions). The index was defined as the HWHM of the respective curves (Fig. 2J). (F and H) Plots of the example neuron of the VP weights of each trial under both V and wood conditions. (G) Pattern of VP weight in the population (n = 69) neural activity from 2 monkeys in both V arm and wood conditions. (I) Comparison of the dynamic of VP weight of the population neurons between the arm and the wood conditions. Error bars represent 1 SEM. **P < 0.01.
