Age-dependent changes in the neural substrates of empathy in autism spectrum disorder

In typical development, empathic abilities continue to refine during adolescence and early adulthood. Children and adolescents with autism spectrum disorders (ASD) show deficits in empathy, whereas adults with ASD may have developed compensatory strategies. We aimed at comparing developmental trajectories in the neural mechanisms underlying empathy in individuals with ASD and typically developing control (TDC) subjects. Using an explicit empathizing paradigm and functional magnetic resonance imaging, 27 participants with ASD and 27 TDC aged 12–31 years were investigated. Participants were asked to empathize with emotional faces and to either infer the face’s emotional state (other-task) or to judge their own emotional response (self-task). Differential age-dependent changes were evident during the self-task in the right dorsolateral prefrontal cortex, right medial prefrontal cortex, right inferior parietal cortex, right anterior insula and occipital cortex. Age-dependent decreases in neural activation in TDC were paralleled by either increasing or unchanged age-dependent activation in ASD. These data suggest ASD-associated deviations in the developmental trajectories of self-related processing during empathizing. In TDC, age-dependent modulations of brain areas may reflect the ‘fine-tuning’ of cortical networks by reduction of task-unspecific brain activity. Increased age-related activation in individuals with ASD may indicate the development of compensatory mechanisms.     

The Mother,The Psychoanalyst,The Poet and The Artist: Containment and Growth of The Mind

This paper considers the difficulties which humans have in using and developing their capacity for thought. Growth of the human mind, through attunement of the mother's unconscious experience with the infant's, is explored along with the distortions which arise because of aversion to uncertainty and suffering. It then looks at psychoanalysis and the verbal and visual arts in the light of the maternal function, and the way in which they also promote the growth of the mind. Four products of the human mind – an excerpt from an infant observation published in 1998, some post‐Kleinian psychoanalytic clinical case material from the 1980s, John Keats's 19th century Ode to a Nightingale and Lucas Cranach's 1526 painting, Adam and Eve – are used to illustrate some of the similarities and differences among them in giving conscious form to the unconscious.     

The Effects of Anxiety on Affective Learning and Serial Position Recall

Sixty-five college-aged adults participated in a study that examined the effects of trait and state anxiety on learning positive and negative emotional words from the Affective Auditory Verbal Learning Test (AAVL). Self-reported state and trait anxiety were measured via Speilberger's State-Trait Anxiety Inventory (STAI). Each participant completed the five learning trials and delayed recall trial of the positive and negative word lists; order of administration for the word lists was counterbalanced across participants. Using ANOVA, initial analyses revealed significant effects for order of administration of the positive and negative word lists. ANCOVAs (using state and trait anxiety as covariates) yielded a significant interaction involving serial position, trial, and state anxiety as well as an interaction involving serial position, trial, and trait anxiety. Post hoc analyses did not support a priori hypotheses. However, state anxiety was associated with decreased word recall on the first learning trial. The results of this study indicate that state anxiety is initially associated with decreased performance when learning emotional words. However, these initial effects dissipate with subsequent learning trials. Implications for task performance are discussed.     

Early visual ERPs are influenced by individual emotional skills

Processing information from faces is crucial to understanding others and to adapting to social life. Many studies have investigated responses to facial emotions to provide a better understanding of the processes and the neural networks involved. Moreover, several studies have revealed abnormalities of emotional face processing and their neural correlates in affective disorders. The aim of this study was to investigate whether early visual event-related potentials (ERPs) are affected by the emotional skills of healthy adults. Unfamiliar faces expressing the six basic emotions were presented to 28 young adults while recording visual ERPs. No specific task was required during the recording. Participants also completed the Social Skills Inventory (SSI) which measures social and emotional skills. The results confirmed that early visual ERPs (P1, N170) are affected by the emotions expressed by a face and also demonstrated that N170 and P2 are correlated to the emotional skills of healthy subjects. While N170 is sensitive to the subject’s emotional sensitivity and expressivity, P2 is modulated by the ability of the subjects to control their emotions. We therefore suggest that N170 and P2 could be used as individual markers to assess strengths and weaknesses in emotional areas and could provide information for further investigations of affective disorders.

Piccolo genotype modulates neural correlates of emotion processing but not executive functioning

Major depressive disorder (MDD) is characterized by affective symptoms and cognitive impairments, which have been associated with changes in limbic and prefrontal activity as well as with monoaminergic neurotransmission. A genome-wide association study implicated the polymorphism rs2522833 in the piccolo (PCLO) gene—involved in monoaminergic neurotransmission—as a risk factor for MDD. However, the role of the PCLO risk allele in emotion processing and executive function or its effect on their neural substrate has never been studied. We used functional magnetic resonance imaging (fMRI) to investigate PCLO risk allele carriers vs noncarriers during an emotional face processing task and a visuospatial planning task in 159 current MDD patients and healthy controls. In PCLO risk allele carriers, we found increased activity in the left amygdala during processing of angry and sad faces compared with noncarriers, independent of psychopathological status. During processing of fearful faces, the PCLO risk allele was associated with increased amygdala activation in MDD patients only. During the visuospatial planning task, we found no genotype effect on performance or on BOLD signal in our predefined areas as a function of increasing task load. The PCLO risk allele was found to be specifically associated with altered emotion processing, but not with executive dysfunction. Moreover, the PCLO risk allele appears to modulate amygdala function during fearful facial processing in MDD and may constitute a possible link between genotype and susceptibility for depression via altered processing of fearful stimuli. The current results may therefore aid in better understanding underlying neurobiological mechanisms in MDD.     

A Historical View of the Stress Field

Abstract

An analysis is presented of selected aspects of stress theory and research in biology and medicine, both before and after the introduction of Selye's stress formulations, which have been of major importance in the development and popularity of this research area. An attempt is made to explore some possible sources of present confusion and controversy in the stress field, with a view to the development of new research strategies that may enable us to clarify, update, and revise stress concepts and to facilitate future progress. In particular, it is suggested that an experimental re-evaluation of the concept of the non-specificity of pituitary-adrenal cortical response is a matter of particular strategic importance, if we are to move out of the present prolonged period of stalemate and confusion over stress theory and terminology. Recent experimental studies which suggest that the nonspecificity concept may have been applied erroneously to lower level physiological mechanisms, rather than to higher level psychological processes, are reviewed. The possible implications of this development are discussed in terms of clarifying current concepts and providing guidelines for future lines of approach in stress research.     

Attention modulates the dorsal striatum response to love stimuli

In previous functional magnetic resonance imaging (fMRI) studies concerning romantic love, several brain regions including the caudate and putamen have consistently been found to be more responsive to beloved‐related than control stimuli. In those studies, infatuated individuals were typically instructed to passively view the stimuli or to think of the viewed person. In the current study, we examined how the instruction to attend to, or ignore the beloved modulates the response of these brain areas. Infatuated individuals performed an oddball task in which pictures of their beloved and friend served as targets and distractors. The dorsal striatum showed greater activation for the beloved than friend, but only when they were targets. The dorsal striatum actually tended to show less activation for the beloved than the friend when they were distractors. The longer the love and relationship duration, the smaller the response of the dorsal striatum to beloved‐distractor stimuli was. We interpret our findings in terms of reinforcement learning. By virtue of using a cognitive task with a full factorial design, we show that the dorsal striatum is not activated by beloved‐related information per se, but only by beloved‐related information that is attended.
