Further, when using reward expectancy neurons only, no increase in the decoder’s performance was observed (Δ performance = +0.01 ± 0.02 with n = 30 neurons, p = 0.21), while there was a statistical trend increase in the decoder’s performance when excluding reward expectancy neurons (Δ performance = +0.10 ± 0.04 with n = 99 neurons, p = 0.059).
