In visual oddball studies, deviant compared to standard stimuli elicited a posterior negative ERP at around 100-250 ms. To determine the underlying processes of the negativity, we used the equiprobable sequence in which bar stimuli of five types of orientation were presented with equal probabilities (control 20% each) as well as the oddball sequence in which two stimuli with the closest orientation were presented with different probabilities (deviant 20% and standard 80%). Deviant compared to standard stimuli elicited two negativities at around 100-150 ms with no hemispheric dominance and 200-250 ms with right hemispheric dominance, while deviant compared to control stimuli elicited only a negativity at around 200-250 ms with right hemispheric dominance. These results suggest that the early negativity reflects refractory effect, while the late negativity reflects memory-comparison-based change detection effect (visual mismatch negativity).

It is hypothesized that experiencing positive emotions such as pleasure leads to a perception of the body being in a positive state. This study demonstrated associations among positive mood, brain, and cardiovascular activities by simultaneously recording these activities when positive emotions were evoked in participants watching films revolving around a love story. Heart rate variability analysis revealed increased parasympathetic nervous activity while watching the film. The following brain regions were significantly activated in the positive condition relative to the control condition: medial prefrontal. cortex, thalamus, superior temporal gyrus, inferior frontal gyrus, and cerebellum. Further, covariate analyses indicated that these brain regions were temporally associated with subjective positive mood. Activities of brain regions considered to be related to interoceptive awareness, such as the insular cortex, anterior cingulate cortex, amygdala, and orbitofrontal cortex, were also temporally associated with the cardiovascular change. These results suggest that while an individual experiences positive emotions, activities of the central nervous system and cardiovascular system may be interrelated, and the brain may perceive the body to be in a positive state.

Metacognitive strategies of emotion regulation such as an objective perspective of one's self are known as primary factors in mindfulness intervention. Earlier studies, however, suggest that the effect of mindfulness differs because of the individual variability. In this study, we investigated the influence of the serotonin transporter gene polymorphism during the application of a metacognitive strategy of emotion regulation. Short (S) homozygotes showed more negative emotional states than SL individuals in both metacognition and control conditions. The high frequency of heart rate variability, however, increased in the metacognition condition only in S homozygotes. This result indicated that the metacognitive strategy of emotion regulation is more effective for increasing parasympathetic dominance in S homozygotes than in SL individuals.

Multisensory processing and neural oscillatory responses: separation of visuotactile congruency effect and corresponding electroencephalogram activities Reviewed

Noriaki Kanayama, Hideki Ohira

By using electroencephalogram, we aimed at identifying the neural oscillations corresponding to two subcomponents of the visuotactile congruency process, facilitation and interference effects. The participants identified the location of the tactile stimulus presented at their index finger or thumb while ignoring simultaneous visual stimuli presented at the same (congruent) or different (incongruent) finger. Significant differences in reaction time were found between the congruent or incongruent condition and the unimodal baseline condition, indicating two different effects of visuotactile interaction. Electroencephalogram results showed significant increases in the gamma-band response in the congruent condition and in the theta-band response in the incongruent condition. These results suggest two systems of multisensory interaction. NeuroReport 20:289-293 (C) 2009 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins.

The rubber hand illusion represents all illusory experience during the mislocalization of own hand when correlated visuotactile stimuli are presented to the actual and fake hands. The visuotactile integration process appears to cause this illusion; the corresponding brain activity was revealed in many Studies. In this Study, We investigated the effect of the rubber hand illusion on the crossmodal integration process by measuring EEG. The participants who experienced less intensive illusion showed greater Congruency effect on reaction time (RT), greater power increase at the parietal zero electrode (Pz) and smaller interelectrode synchrony of the gamma band activity. On the other hand, the participants who experienced more intense illusion showed greater interelectrode synchrony. The results suggested that the gamma band activity in the parietal area reflects the visuotactile integration process and that its synchrony causes the illusory intensity.
