A–H, Classification of RMTg neuron types. For each monkey (B and C), the averaged neuronal activity in the 1DR task is shown separately for reward-negative neurons (left) and reward-positive neurons (right). Each group of neurons is further classified into the change-of-value type (top) or the state value type (bottom). The neuronal activity is aligned at fixation point onset, target onset, and reward onset. The thin SDFs indicate the average activity in the first trials after the reversal of the position-reward contingency, while the thick SDFs indicate the average activity except for the first trials. The average activity is shown separately for the reward trials (red) and no-reward trials (blue).
