Figure 8. Performances of the ndBMI by using a data set generated from a Gamma Interval process with different values of the shape parameter k.

Figure 8

(A, C) Ideal ad actual trajectories superimposed to the sensory regions obtained by using data generated by using five different values of the shape parameter Inline graphic of a Gamma interval process used to set the inter-spike intervals of the simulated spike trains. We ran the interface using the Gaussian (A) and Dipole (C) force fields with the Multiple-points algorithm. (B, D) Average within-trajectory position error across the three different conditions shows how the error decreases by increasing the regularity of the spiking of the M1 neurons. The * denotes that wpte depended significantly on Inline graphic (Inline graphic one-way ANOVA) and is placed in correspondence of the values of Inline graphic for which wpte was significantly different from the “reference” condition with Inline graphic (Tukey hsd Inline graphic).
