“…To our knowledge, all previous EEG studies on pain anticipation used uncertain anticipation conditions and compared them with safe, that is, no pain, conditions. Others [Hellwig et al, 2008] applied an uncertain condition (50% of trials) that was comparable to our study and contrasted it with a safe condition. Some studies [Baas et al, 2002;Boecker et al, 2001] compared a highly uncertain pain condition (only 6% of all trials followed by a shock) with a safe condition.…”

“…Dipole modeling suggests generators in midline frontal areas such as the ACC. A more midcentral and posterior parietal SPN has also been reported during the last 1500 ms before actual painful stimulation [Hellwig et al, 2008]. The early SPN showed a broad frontocentral distribution but did not differ between certain or uncertain cues.…”

“…The late SPN had a more central distribution. A more midcentral and posterior parietal SPN has also been reported during the last 1500 ms before actual painful stimulation [Hellwig et al, 2008]. In addition, there is evidence that longer anticipation duration and unpredictability in stimulus timing increases the amplitude of the stimulationrelated P2 component [Clark et al, 2008;Hauck et al, 2007].…”

Our results reflect that during early anticipation uncertainty is strongly associated with affective mechanisms and seems to be a more salient event compared to certain anticipation. During the last 2 s before stimulation, attentional control mechanisms are initiated related to the increased salience of uncertainty. Furthermore, stimulus-specific preparatory mechanisms during certain anticipation also shaped the response to stimulation, underlining the adaptive value of stimulus-targeted preparatory activity which is less likely when facing an uncertain event.

BackgroundDopamine plays an important role in orienting and the regulation of selective attention to relevant stimulus characteristics. Thus, we examined the influences of functional variants related to dopamine inactivation in the dopamine transporter (DAT1) and catechol-O-methyltransferase genes (COMT) on the time-course of visual processing in a contingent negative variation (CNV) task.Methods64-channel EEG recordings were obtained from 195 healthy adolescents of a community-based sample during a continuous performance task (A-X version). Early and late CNV as well as preceding visual evoked potential components were assessed.ResultsSignificant additive main effects of DAT1 and COMT on the occipito-temporal early CNV were observed. In addition, there was a trend towards an interaction between the two polymorphisms. Source analysis showed early CNV generators in the ventral visual stream and in frontal regions. There was a strong negative correlation between occipito-temporal visual post-processing and the frontal early CNV component. The early CNV time interval 500–1000 ms after the visual cue was specifically affected while the preceding visual perception stages were not influenced.ConclusionsLate visual potentials allow the genomic imaging of dopamine inactivation effects on visual post-processing. The same specific time-interval has been found to be affected by DAT1 and COMT during motor post-processing but not motor preparation. We propose the hypothesis that similar dopaminergic mechanisms modulate working memory encoding in both the visual and motor and perhaps other systems.

Hey, what is your choice? Uncertainty and inconsistency enhance subjective anticipation of upcoming information in a social context

This research examined whether uncertainty would modulate subjective anticipation during social interactions as it does in the non-social context, and further explored how response consistency between participants would influence one's anticipation. We set up an encyclopedic knowledge quiz involving two anonymous same-sex players and manipulated the difficulty of proposed questions (high-uncertainty accompanies highly difficult questions). An enlarged stimulus-preceding negativity was observed when participants were anticipating the presentation of their counterparts' responses to high-uncertainty questions (versus low-uncertainty ones), as well as when they were anticipating the display of correct answers to high-uncertainty questions after they found out that responses given by their partners were inconsistent (versus consistent) with their own. In addition, inconsistent responses gave rise to a more salient difference wave reward positivity and a more positive P300 during the feedback stage. Taken together, these results suggested that both uncertainty and inconsistency would enhance subjective anticipation of upcoming information during social interactions, and that inconsistency would strengthen one's concern and attention over outcomes.
