Emergence of a Stable Cortical Map for Neuroprosthetic Control

Specificity of neural adaptations to the decoder.

(A) Reversible drop in performance with a change in the applied decoder. The upper panel compares the two applied decoders. Pair of bars shows the mean weight for each neuron in each decoder (paired t-test, an asterisk [*] indicates p<0.05, FDR corrected for multiple comparisons). The lower panel shows the number of correct and incorrect trials in the presence of DecoderOLD (black bar) and DecoderNEW (green bar). a.u., arbitrary units. (B) Changes in performance for similar trials (n = 4) in both monkeys with substitution of newly trained decoders (mean±standard error; ANOVA, p<10−5; the asterisk [*] indicates p<0.05, FDR corrected for multiple comparisons).
