Economists, nutritionists, urban planners and public health professionals had been calculating what the scale of the relief task ahead would be.
During the battle Lieutenant Colonel Daniel F. Shungel – Commander of Company C, 5th Special Forces Group – had to fight his way out of the camp in order to escape the North Vietnamese attack, until rescued by a relief task force led by Major George Quamo.
No voxels within this region showed a significant relationship with relief hedonics during the relief task.
In the relief task, a warning signal was 50% predictive of intense pain (Figure 1A).
However, a similar relationship was not found for the relief task.
In summary, we compared hedonic and BOLD responses during a relief task with responses during an appetitive reward task.
Appetitive reward and relief task activation converged in the ventromedial prefrontal cortex, including the rostral anterior cingulate region.
Here, BOLD signal in the NAc correlated significantly with subjective reports of pleasantness during the relief task, but not during the appetitive reward task (Figure 3).
Trials of the two tasks were intermixed during the scan, such that each relief trial was followed by an appetitive reward task trial, which was followed by another relief task trial, and so on.
To identify areas where activity in the two tasks differed significantly, we performed a paired t-test comparing the main effect of the relief task and the reward task for each participant.
