We first tested whether we could replicate previous findings that unpredicted rewards activated striatal regions, while predictable rewards induced activity in the vmPFC [3], [4].
She sounded like a loving, needy, mildly anxious personality type who was easily shaken by unfamiliar activity or unpredicted events.
There was a scene happening, unexpected, unpredictable and unpredicted, but there and real.
As noted above, the dopamine-producing neurons of the pars compacta of the substantia nigra display short periods of increased activity after the unpredicted presentation of food or liquid reinforcers and are believed to be involved in acquisition of behavior based on reinforcement.
Indeed, it was previously reported that the HvLDI antisense lines showed unpredicted pleiotropic effects on numerous enzyme activities, including α- and β-amylases, starch synthases, as well as starch granule types, all of which affect malt extract [ 35].
The crisis was not an act of God, unpredictable to and unpredicted by ordinary mortals.
Changes in specificity may cause phosphorylation and activation of unpredicted targets that lead to disease states.
To summarize, our findings replicate previous results that reward-predicting cues and unpredicted rewards are associated with enhanced activity of the ventral striatum, while predictable rewards induce an increased BOLD response in the vmPFC.
Indeed, the contrast of predicted vs. unpredicted rewards was associated with significant activity in the medial orbitofrontal cortex (-3, 39, -15; Fig. 4A), while the reverse contrast showed significant activity in bilateral ventral striatum (left caudate nucleus, -12, 12, 6; and a cluster centered in the internal capsule between caudate, nucleus accumbens and putamen, 15, 9, 0; Fig. 4B).
A gene with carboxy-lyase activity and one of unpredicted function were significantly overexpressed in accessory glands of sexually mature males.
As described in the Introduction, we were particularly interested in activity during consumption of predicted and unpredicted rewards.
