NEUROSCIENCE LETTERS Vol. 482 ( 3 ) page： 220 - 224 2010.10

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER IRELAND LTD

Life choices (e.g., occupational choice) often include situations with two or more possible correct answers, thereby putting us in a situation of conflict. Recent reports have described that the evaluation of conflict might be crucially mediated by neural activity in the dorsal anterior cingulate cortex (dACC), although the reduction of conflict might rather be associated with neural activity in the medial prefrontal cortex (MPFC). What remains unclear is whether these regions mutually interact, thereby raising the question of their functional connectivity during conflict situations. Using psychophysiological interaction (PPI) analyses of functional magnetic resonance imaging (fMRI) data, this study shows that the dACC co-varied significantly higher with the MPFC during an occupational choice task with two possible correct answers when compared to the control task: a word-length task with one possible correct answer. These results suggest that the MPFC has a functional relation with dACC, especially in conflict situations where there is no objective correct answer. Taken together, this lends support to the assumption that the MPFC might be crucial in biasing the decision, thereby reducing conflict. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

The Somatic Marker Revisited: Brain and Body in Emotional Decision Making

Hideki Ohira

EMOTION REVIEW Vol. 2 ( 3 ) page： 245 - 249 2010.7

Language：English Publishing type：Research paper (scientific journal) Publisher：SAGE PUBLICATIONS INC

One important function of emotions is to guide decision making and behaviors for survival in complex environments. In the context of such reasoning, the somatic marker hypothesis (Damasio, 1994) has argued that bodily states are represented in specific brain regions, such as the insula, and would play critical roles in decision making. However, it still remains unclear what causal roles bodily states would play in decision making, and how the bodily states would change accompanying decision making. Thus, the aim of this article is to reconsider aspects of the brain and bodily states in decision making based on recent findings. Questions for future research are proposed based on such findings.

Phasicheart rate responses for anticipated threat situations. Reviewed International journal

Murakami, H, Matsunaga,M, Ohira, H

International Journal of Psychophysiology Vol. 77 ( 1 ) page： 21 - 25 2010.7

Language：English Publishing type：Research paper (scientific journal)

The effects of anticipated threat situations and the valence of the stimuli on the deceleration of the phasic heart rate (HR) were investigated in a single experiment using an S1-S2 paradigm. There were certain S1 cues that were always expected to be followed by neutral pictures (S2 stimuli), and uncertain S1 cues that had a 50% probability of being followed by neutral or unpleasant pictures (S2 stimuli). Greater phasic HR deceleration was observed for S2 stimuli following uncertain S1 cues than for S2 stimuli following certain S1 cues, regardless of the valence of the S2 stimuli. This result suggests that an anticipated threat situation in which participants anticipate facing potentially unpleasant stimuli leads to the allocation of more attentional resources. Additionally, correlation analyses revealed that highly anxious individuals tended to show greater HR deceleration in response to unpleasant stimuli, possibly reflecting maladaptive attentional bias for threat stimuli.

Human Visual System Automatically Encodes Sequential Regularities of Discrete Events

Kimura Motohiro, Schroeger Erich, Czigler Istvan, Ohira Hideki

JOURNAL OF COGNITIVE NEUROSCIENCE Vol. 22 ( 6 ) page： 1124 - 1139 2010.6

Language：English Publishing type：Research paper (scientific journal) Publisher：Journal of Cognitive Neuroscience

For our adaptive behavior in a dynamically changing environment, an essential task of the brain is to automatically encode sequential regularities inherent in the environment into a memory representation. Recent studies in neuroscience have suggested that sequential regularities embedded in discrete sensory events are automatically encoded into a memory representation at the level of the sensory system. This notion is largely supported by evidence from investigations using auditory mismatch negativity (auditory MMN), an event-related brain potential (ERP) correlate of an automatic memory-mismatch process in the auditory sensory system. However, it is still largely unclear whether or not this notion can be generalized to other sensory modalities. The purpose of the present study was to investigate the contribution of the visual sensory system to the automatic encoding of sequential regularities using visual mismatch negativity (visual MMN), an ERP correlate of an automatic memory-mismatch process in the visual sensory system. To this end, we conducted a sequential analysis of visual MMN in an oddball sequence consisting of infrequent deviant and frequent standard stimuli, and tested whether the underlying memory representation of visual MMN generation contains only a sensory memory trace of standard stimuli (trace-mismatch hypothesis) or whether it also contains sequential regularities extracted from the repetitive standard sequence (regularity-violation hypothesis). The results showed that visual MMN was elicited by first deviant (deviant stimuli following at least one standard stimulus), second deviant (deviant stimuli immediately following first deviant), and first standard (standard stimuli immediately following first deviant), but not by second standard (standard stimuli immediately following first standard). These results are consistent with the regularity-violation hypothesis, suggesting that the visual sensory system automatically encodes sequential regularities. In combination with a wide range of auditory MMN studies, the present study highlights the critical role of sensory systems in automatically encoding sequential regularities when modeling the world. © 2009 Massachusetts Institute of Technology.

EEG evidence of face-specific visual self-representation

Makoto Miyakoshi, Noriaki Kanayama, Tetsuya Iidaka, Hideki Ohira

NEUROIMAGE Vol. 50 ( 4 ) page： 1666 - 1675 2010.5

Language：English Publishing type：Research paper (scientific journal) Publisher：ACADEMIC PRESS INC ELSEVIER SCIENCE

Cognitive science has regarded an individual's face as a form of representative stimuli to engage self-representation. The domain-generality of self-representation has been assumed in several reports, but was recently refuted in a functional magnetic resonance imaging study (Sugiura et al., 2008). The general validity of this study's criticism should be tested by other measures to compensate for the limitation of the time resolution of the blood-oxygen-level-dependent (BOLD) signal. In this article, we report an EEG study on the domain-generality of visual self-representation. Domain-general self-representation was operationally defined as the self-relevance common to one's own Face and Cup; three levels of familiarity, Self. Familiar, and Unfamiliar, were prepared for each. There was another condition, Visual Field, that manipulated visual hemifield during stimulus presentation, but it was collapsed because it produced no interaction with stimulus familiarity. Our results confirmed comparable phase resetting in both domains in response to familiarity manipulation, which occurred within the medial frontal area during 270-390 ms poststimulus and in the theta band. However, self-specific dissociation was observed only for Face. The results here support the conclusion that visual self-representation is domain-specific and that the oscillatory responses observed suggest evidence of face-specific visual self-representation. Results also revealed an inter-trial phase coherency decrease specifically for Self-Face within the right fusiform area during 170-290 ms poststimulus and in the alpha and theta band, suggesting reduced functional demand for Self-Face represented by sharpened networks.

The authors investigated whether self-knowledge has a function to reduce conflict by biasing one of two choices during occupational choice (e.g., Which occupation do you think you could do better-dancer or chemist). In the three experiments, event-related brain potentials were recorded. Experiment I revealed that the amplitude of the conflict-related negativity (CRN) reflects strength of conflict during occupational choice. Results of Experiment 2 demonstrated that the CRN amplitude during occupational choice was smaller when self-knowledge was activated than when other-knowledge was activated. Experiment 3 showed that the CRN amplitude during occupational choice was decreased more when self-knowledge that biases one choice of occupation was activated than when self-knowledge that does not bias was activated. These results suggest that self-knowledge reduces conflict by biasing one of multiple choices in situations where two or more possible correct answers can be given.
