Effect of reward sequences on changes in accuracy and reaction times (RTs).
<p>(A) The change in accuracy showed an increase in all cases, but to different extents. The highest increase in accuracy was for one rewarded and one unrewarded trial (U-R and R-U), due to strengthening of the cortico-striatal projection to dSPNs of the optimal choice along with strengthening...

| Summary: | <p>(A) The change in accuracy showed an increase in all cases, but to different extents. The highest increase in accuracy was for one rewarded and one unrewarded trial (U-R and R-U), due to strengthening of the cortico-striatal projection to dSPNs of the optimal choice along with strengthening of cortico-striatal projections to iSPNs of the sub-optimal choice. (B) The change in RTs after plasticity for the four outcome sequences. All sequences involving at least one rewarded trial yielded a decrease in RT, whereas the sequence with two consecutive unrewarded trials (U-U) induced an increase in RT.</p> <p>(TIFF)</p> |
