Figure 3. A diffusion process underlies NB stimulation-induced improved performance.

Figure 3.

A. Bump center vs. time for 50 network initializations (for a cue presented at 0 degrees). The bump center follows a random walk. B. Diffusivity vs. FF input. Diffusion decreases for strong enough FF inputs. Shaded area: bootstrapped 95% confidence intervals. Grey line, relative bump amplitude (see Material and Methods). C. Distributions of bump centers endpoint location for two different values of the FF input (for 1000 initial conditions). Lines are kernel density estimates. D. Two sources of errors in the experimental data: response bias and response variance. E-F. Distributions of saccades (i.e., mean corrected saccadic endpoint, see Material and Methods) in Remember 1st and Remember 2nd trials in the data. NB stimulation leads to a sharper distribution of endpoints (see regression analysis, Material and Methods). Line are Gaussian fits. Blue: control. Orange: NB stimulated trial.
