Figure 9.

Decoding of reward size during the waiting period when spike vectors from the reward delivery period were used for encoding. A reconstruction ensemble of 26 neurons was used, and the decoding time window was 1.5 s. For all four two-trial blocks (see also Fig. 7), a decoding score was obtained significantly above chance level. The fourth trial block showed a significantly lower decoding score with respect to the previous three trial blocks. Error bars indicate SEM values.
