Do nucleus accumbens neurons track behavioral preferences and reward outcomes during risky decision making?
Consistent with previously demonstrated alterations in prospective reward value with effort and delay, NAc neurons encode information during reward-predictive cues and outcomes in a risk task that tracked the rats' preferred responses. This processing appears to contribute to subjective encoding of anticipated outcomes and thus may function to bias future risk-based decisions.
The present data indicate that a substantial number of patients develop gallbladder complications after LRYGB. Furthermore, CPC can safely be performed during LRYGB. Based on these findings, CPC should be considered a reasonable approach in severely obese patients undergoing LRYGB.
