    ABSTRACT: The tendency to approach or avoid novel people is a fundamental human behavior and is a core dimension of social anxiety. Resting state fMRI was used to test for an association between social inhibition and intrinsic connectivity in 40 young adults ranging from low to high in social inhibition. Higher levels of social inhibition were associated with specific patterns of reduced amygdala-cingulate cortex connectivity. Connectivity was reduced between the superficial amygdala and the rostral cingulate cortex and between the centromedial amygdala and the dorsal anterior cingulate cortex. Social inhibition also modulated connectivity in several well-established intrinsic networks; higher social inhibition correlated with reduced connectivity with default mode and dorsal attention networks and enhanced connectivity in salience and executive control networks. These findings provide important preliminary evidence that social inhibition reflects differences in the underlying intrinsic connectivity of the brain in the absence of social stimuli or stressors.

    ABSTRACT: Recent work suggests that leukocyte telomere length (LTL), a marker of cellular aging, is sensitive to effects of social stress and may also provide early indication of premature aging. Using data from a birth cohort with LTL information at birth and in middle adulthood we examined a potential source of race-based health disparity by testing the hypothesis that Blacks would demonstrate a faster rate of telomere shortening than Whites. Linear regression analyses were conducted and adjusted for pack years, BMI, education and social factors, diet, exercise, marital status, and age. At birth black individuals had LTLs that were longer, on average, than their White counterparts (b = 3.85, p < 0.01). However, rate of shortening was greater for Blacks, who showed a larger difference in length between birth and adulthood (b = 5.10, p = 0.01) as compared with Whites, resulting in smaller racial differences in absolute adult LTL.

    ABSTRACT: The study evaluates error and feedback related processing in children with Specific Language Impairment (SLI), and in age and gender matched controls. Participants performed two tasks which varied in the extent to which feedback was provided following each response. Although no group differences were found in accuracy and response time measures, children with SLI corrected a smaller proportion of their errors in comparison with the control group. Neurophysiological data pointed to error and feedback processing differences between the two groups. Errors committed by the control group elicited error-related ERP components (ERN, Pe), while these components were attenuated in the SLI group. A posterior positivity was elicited in association with incorrect responses in both groups. When a feedback stimulus informed the participants about the accuracy of the response, the feedback, rather than the response, elicited an ERN in the control group, while no ERN was elicited in the SLI group. These results suggest that children with SLI have an impaired ability to self-monitor performance and to take advantage of performance feedback.

    ABSTRACT: Executive attention and its relationship with effortful control (EC) were investigated in children with ADHD (n = 24), autism spectrum disorder (ASD; n = 20), and controls (n = 21). Executive attention measures included flanker-performance and event-related potentials (N2, P3, and ERN). EC was assessed using questionnaires. Only the ERN was found to be robustly related to EC across groups. N2 did not differ between groups and only children with ADHD + ODD showed diminished executive attention as expressed in RT and P3. In ADHD, monitoring of incorrect (ERN) and correct (CRN) responses was diminished. Overall, the link between EC and executive attention was less strong as expected and varied depending on group and measure considered. All groups were able to detect conflict (N2) and all but ADHD + ODD were able to allocate extra attention in order to respond correctly (P3). Findings indicate a general reduced response monitoring in ADHD.

    ABSTRACT: Alcohol misuse in bipolar disorder (BD) has a negative impact on illness progression. The NMDA/glutamatergic system is implicated in BD pathophysiology and is critically involved in the effects of alcohol on the brain. Mismatch negativity (MMN) is purported to reflect NMDA receptor output, providing a measure for investigating this association. Forty-two patients and 34 controls (16 - 30 years) were split into low and high-risk drinkers (based on the Alcohol Use Disorders Identification Test) and underwent a two-tone passive auditory oddball, duration deviant MMN paradigm. Multiple regression models revealed risky drinking and BD diagnosis were predictors of impaired temporal MMN. Potentially reflecting an additive effect of alcohol on a perturbed NMDA/glutamatergic system in BD, these findings highlight alcohol as both a modifiable risk factor of neurobiological impairments and as a potential confounder in MMN studies. Given the increasing use of glutamatergic agents for BD treatment, this finding is important clinically.

    ABSTRACT: This study correlated lifetime PTSD diagnostic status with interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) levels, and tested whether these correlations are sensitive to psychological context. Midlife women attended two research visits where blood was drawn (beginning of visits) and saliva and oral mucosal transudate were collected (beginning and end of visits) to measure IL-6 and sIL-6R. Women were classified as PTSD-/- (past and current symptoms below subsyndromal levels), PTSD+/- (past symptoms at or above subsyndromal levels), or PTSD + + (past and current symptoms at or above subsyndromal levels). PTSD+/+ women, compared to the other women, showed more negative emotion at the beginning of the visits, higher salivary IL-6 levels at the beginning versus end of visits, and positive correlations between negative emotion, salivary IL-6, and plasma sIL-6R. Their plasma sIL-6R levels exceeded those of the PTSD+/- women. Overall, IL-6 sensitivity to anticipation and to negative emotions, and higher sIL-6R levels, differentiated persistent versus remitted PTSD.

    ABSTRACT: The study investigated brain responses to emotional adjectives (describing moods) and neutral adjectives (describing objects) within an emotional and neutral context. Participants were randomly assigned to an emotional context, neutral context or zero context group, where they all viewed random sequences of emotional and neutral adjectives. Adjectives were intermixed with IAPS pictures of positive and negative valence for the emotional context group, neutral pictures for the neutral context group and blank screens for the zero context group. There were differences in the processing of emotional and neutral adjectives in all groups. Within the emotional context, these differences were noted as early as 40-80ms after the word onset (P1), with greater positivity evoked by the negative adjectives as opposed to the positive and neutral ones only in the right hemisphere. The right hemisphere was also specifically implicated in the processing of all verbal stimuli at later stages (P2, P3 and LPP window). The most robust effects of the words’ valence were observed in the neutral context group, as early as the P2 (135-175ms) potential, which was greater in response to the positive adjectives than in response to the negative and neutral ones. A similar effect could be observed on the P3b component. There was also a greater negativity of the N400 potential (400-500ms) in response to the neutral adjectives. Within the zero context group only the N400 effect was visible. Thus the context in which adjectives were read seemed to influence word processing on many levels. The seeming preference for positive words can be explained in terms of the specific positivity offset phenomenon. Finally, a special status of the right hemisphere in linguistic and affective processes is suggested, since its activation was especially pronounced in response to all kinds of verbal stimuli at many different stages of word encoding.
