Table 1.

Distribution of neurons (group 3; n = 65) that responded to both positive and negative feedback by activation, inhibition, or both

Positive feedback (success)/negative feedback (error) Total units Success > error Error > success NS
Activation/activation 49 8 33 8
Activation/inhibition 4 4 0 0
Inhibition/activation 8 0 8 0
Inhibition/inhibition 4
Total 65 12 41

Trials in which the positive feedback (reward) was given out of the task context were excluded. NS, Not significant.
