Basolateral and central amygdala orchestrate how we learn whom to trust.

Cooperation and mutual trust are essential in our society, yet not everybody is trustworthy. In this fMRI study, 62 healthy volunteers performed a repeated trust game, placing trust in a trustworthy or an untrustworthy player. We found that the central amygdala was active during trust behavior planning while the basolateral amygdala was active during outcome evaluation.

Neural Correlates of Interpersonal Space Permeability and Flexibility in Autism Spectrum Disorder.

Previous research indicates that the size of interpersonal space at which the other is perceived as intrusive (permeability) and the ability to adapt interpersonal distance based on contextual factors (flexibility) are altered in Autism Spectrum Disorder (ASD). However, the neurophysiological basis of these alterations remains poorly understood. To fill this gap, we used fMRI and assessed interpersonal space preferences of individuals with ASD before and after engaging in cooperative and non-cooperative social interactions.

Fairness norm violations in anti-social psychopathic offenders in a repeated trust game.

Psychopathic offenders have a high propensity to violate social norms, as indicated for instance by their widespread lying and cheating behaviour. The reasons for their norm violations are not well understood, though, as they are able to recognise norms in a given situation and also punish norm violators. In this study, we investigated whether psychopathic offenders would violate fairness norms during a repeated trust game because of increased profit-maximising concerns.

The Human Basolateral Amygdala Is Indispensable for Social Experiential Learning.

Trust and betrayal are central to our social world, and adaptive responses to generous and selfish behavior are crucial to our economic and social well-being [1]. We learn about others' trustworthiness through trial and error during repeated interactions [2]. By reinforcing and suppressing behavior during positive and negative interactions with conspecifics, rodent research has established a crucial role for the basolateral amygdala (BLA) in social experiential learning [3, 4].

Efficacy and Safety of Massage for Osteoarthritis of the Knee: a Randomized Clinical Trial.

Background: Current treatment options for knee osteoarthritis have limited effectiveness and potentially adverse side effects. Massage may offer a safe and effective complement to the management of knee osteoarthritis.

Objective: Examine effects of whole-body massage on knee osteoarthritis, compared to active control (light-touch) and usual care.

Slow touch targeting CT-fibres does not increase prosocial behaviour in economic laboratory tasks.

Field studies have demonstrated that humans become more generous, helpful and compliant after having been touched by another person. Here, we explored whether these effects are larger for touch activating the C-tactile (CT) fibres, as it is ascribed a particular role in establishing and maintaining bonds and affiliative interactions. The role of CT-targeted and non-targeted touch on prosocial behaviour was investigated in three different experiments using a trust game and a task measuring individual differences in social value orientations (the SVO task).

Massage Therapy and Quality of Life in Osteoarthritis of the Knee: A Qualitative Study.

Objective: We hypothesized that participants receiving Swedish massage would experience benefits such as stress reduction and enhanced quality of life, in addition to the osteoarthritis-specific effects assessed in a randomized controlled clinical trial.

Design: Qualitative methods were used to explore a deeper contextual understanding of participants' experiences with massage and osteoarthritis, in addition to the quantitative data collected from primary and secondary outcome measures of the dose-finding study.

Setting: Two community hospitals affiliated with academic health centers in Connecticut and New Jersey.

Testosterone abolishes implicit subordination in social anxiety.

Neuro-evolutionary theories describe social anxiety as habitual subordinate tendencies acquired through a recursive cycle of social defeat and submissive reactions. If so, the steroid hormone testosterone might be of therapeutic value, as testosterone is a main force behind implicit dominance drive in many species including humans. We combined these two theories to investigate whether the tendency to submit to the dominance of others is an implicit mechanism in social anxiety (Study-1), and whether this can be relieved through testosterone administration (Study-2).

Project ASPIRE: Incorporating Integrative Medicine Into Residency Training.

Griffin Hospital, a community hospital affiliated with Yale School of Public Health and Yale School of Medicine, received Health Resources and Services Administration funding to strengthen and improve its combined internal medicine and general preventive medicine residency program by incorporating an integrative medicine curriculum. The purpose of project ASPIRE (Advancing Skills of Preventive medicine residents through Integrative medicine Education, Research and Evaluation) was to create, implement, and evaluate a needs-based, innovative training curriculum in integrative medicine. Through this robust new training, the authors aimed to produce preventive medicine-trained physicians with competencies in integrative medicine to collaboratively work with other integrative medicine practitioners in interdisciplinary teams to provide holistic, patient-centered care.

Cortisol administration induces global down-regulation of the brain's reward circuitry.

Research in rodents and humans has shown divergent effects of the glucocorticoids corticosterone and cortisol (CRT) on reward processing. In rodents, administration of CRT increases reward drive by facilitating dopamine release in the ventral striatum. In humans, correspondingly, risky decision-making increases when CRT levels are elevated.

Acute effects of Sceletium tortuosum (Zembrin), a dual 5-HT reuptake and PDE4 inhibitor, in the human amygdala and its connection to the hypothalamus.

The South African endemic plant Sceletium tortuosum has a long history of traditional use as a masticatory and medicine by San and Khoikhoi people and subsequently by European colonial farmers as a psychotropic in tincture form. Over the past decade, the plant has attracted increasing attention for its possible applications in promoting a sense of wellbeing and relieving stress in healthy individuals and for treating clinical anxiety and depression. The pharmacological actions of a standardized extract of the plant (Zembrin) have been reported to be dual PDE4 inhibition and 5-HT reuptake inhibition, a combination that has been argued to offer potential therapeutic advantages.

Development of a manualized protocol of massage therapy for clinical trials in osteoarthritis.

Background: Clinical trial design of manual therapies may be especially challenging as techniques are often individualized and practitioner-dependent. This paper describes our methods in creating a standardized Swedish massage protocol tailored to subjects with osteoarthritis of the knee while respectful of the individualized nature of massage therapy, as well as implementation of this protocol in two randomized clinical trials.

Methods: The manualization process involved a collaborative process between methodologic and clinical experts, with the explicit goals of creating a reproducible semi-structured protocol for massage therapy, while allowing some latitude for therapists' clinical judgment and maintaining consistency with a prior pilot study.

Regional differences in the developmental trajectory of lateralization of the language network.

The timing and developmental factors underlying the establishment of language dominance are poorly understood. We investigated the degree of lateralization of traditional frontotemporal and modulatory prefrontal-cerebellar regions of the distributed language network in children (n = 57) ages 4 to 12--a critical period for language consolidation. We examined the relationship between the strength of language lateralization and neuropsychological measures and task performance.

Functional anatomy of listening and reading comprehension during development.

Listening and reading comprehension of paragraph-length material are considered higher-order language skills fundamental to social and academic functioning. Using ecologically relevant language stimuli that were matched for difficulty according to developmental level, we analyze the effects of task, age, neuropsychological skills, and post-task performance on fMRI activation and hemispheric laterality. Areas of supramodal language processing are identified, with the most robust region being left-lateralized activation along the superior temporal sulcus.

The fMRI success rate of children and adolescents: typical development, epilepsy, attention deficit/hyperactivity disorder, and autism spectrum disorders.

Functional magnetic resonance imaging (fMRI) in children is increasingly used in clinical application and in developmental research; however, little is known how pediatric patient and typically developing populations successfully complete studies. We examined pediatric success rates with epilepsy, attention deficit/hyperactivity disorder (ADHD), autism spectrum disorders (ASD), and typically developing children (TYP). We also examined the affect of age, and, for ADHD populations, medication status on success rates.
