ABSTRACT We investigated the relationship between action-outcome contingency and stimulus-preceding negativity (SPN), a motivationally sensitive event-related potential. Neuroimaging studies have shown that insular cortex (a known source of the SPN) is more activated prior to rewards that are contingent on prior correct action than rewards that are given gratuitously. We compared two gambling tasks, one in which the participant attempted to guess the profitable key-press option (choice) and one in which rewards were simply given at random (no-choice). The SPN that developed in anticipation of feedback was larger in the choice condition, especially at right anterolateral sites. These findings suggest that the SPN specifically reflects the expectation of response reinforcement, rather than anticipatory attention toward emotionally salient stimuli.

    • "A common aspect between the SPN and FRN components is that both have been associated with reward processing (feedback expectancy vs. evaluation of feedback) and dopaminergic midbrain regulatory mechanisms. However, few experiments have studied both components simultaneously (however, see Donkers et al., 2005; Masaki et al., 2006; 2010). "

    ABSTRACT: The neural basis of feedback expectation, which is crucial in learning theory, has only been minimally studied. Stimulus-preceding negativity (SPN), an ERP component that appears prior to the presentation of feedback, has been proposed as being related to feedback expectation. The present study showed, for the first time, amplitude modulations of the SPN component during learning acquisition in a trial-by-trial associative learning task. The results indicate that SPN could be a plausible electrophysiological index of the cognitive processes engaged while expecting the appearance of relevant feedback during reinforcement learning.

    • "The limiting issue, however, is that responses are very much coupled to the neurotransmitter dopamine and activity of the basal ganglia, just as the performance monitoring/reward anticipation system that we are trying to study. Although the SPN is larger when rewards are contingent on prior action than when they are given gratuitously (Masaki et al., 2010), it would be useful to study motivational processes in isolation. Second, with only few exceptions (e.g., Masaki et al., 2006), FRN investigators only analyze their ERP data after the feedback, because that is when the FRN occurs, and thus do not report on the SPN that precedes it.

    ABSTRACT: Neurobiological accounts of the dopaminergic reward system and psychophysiological explanations of the error-related negativity (ERN) both emphasize the comparison of expected versus actual outcome for voluntary actions. The stimulus-preceding negativity (SPN) constitutes a valuable index of that expectation, in that it has high temporal resolution and its anatomical, cognitive and affective correlates have been reasonably well characterized. This review links established findings regarding the SPN to current research on the dorsal and ventral attention systems, somatic marker hypothesis, ERN, the reward system and relevant neurological and psychiatric findings. Special emphasis is given to the pre-feedback SPN and its origin within anterior insular cortex.

    ABSTRACT: In recent years, micro-bubbles are seen in the photoresist film by advanced laser scan particle detector. These micro-bubbles have potential to cause fatal defects in IC products. Therefore, we need to suppress development of micro-bubbles as possible. First of all, we specified a photoresist process step which micro-bubbles develop. Then, we found a development mechanism of microbubbles that can be explained by considering the behavior of a viscous fluid on a rotating disk. From these experiments and mechanism, we suggest a new photoresist coating method "Step Dynamic Coating", which can suppress micro-bubbles drastically. Moreover, photoresist process trends show micro-bubbles will become more troublesome in the future. We do claim "Step Dynamic Coating" is one of the best solution to suppress microbubbles since this is based on our understanding of the micro-bubble development mechanism
