Decomposing the brain: components and modes, networks and nodes

Smith and colleagues recently presented a temporal independent component analysis (tICA) decomposition of resting-state functional MRI data. Compared to the widely used spatial ICA (sICA), tICA better allows for a brain region to engage in multiple, independent interactions with other regions and will potentially offer new insights into brain function.

MİLLİ İNKILAP AND THE THRACE INCIDENTS OF 1934

While anti-Semitism had been manifested in Europe since the Middle Ages, the emergence of the Nazi regime raised that phenomenon to a new level. Some publications supported by Nazi Germany tried to effect public opinion in Turkey regarding “scientific” anti-Semitism. The authors of this study support the view that this ideology has not been able to achieve broad support from the Turkish nation or its government. Nevertheless, anti-Semitism did reach Turkey through foreign publications. The specific anti-Semitic events that occurred in the Thrace Region of Turkey in 1934 and the anti-Semitic Milli ?nk?lap (National Revolution), which had a pivotal role in those events, were inspired by Nazi Germany. Nevertheless, Germany does not seem to have played an active role during the events. This article will examine the issues of the openly anti-Semitic Milli ?nk?lap, published from 1 May 1934 to 1 July 1934 and try to compare the influence of Julius Streicher's infamous Der Stürmer on the ideology and content of Milli ?nk?lap.     

Mice optimize timed decisions about probabilistic outcomes under deadlines

Optimal performance in temporal decisions requires the integration of timing uncertainty with environmental statistics such as probability or cost functions. Reward maximization under response deadlines constitutes one of the most stringent examples of these problems. The current study investigated whether and how mice can optimize their timing behavior in a complex experimental setting under a response deadline in which reward maximization required the integration of timing uncertainty with a geometrically increasing probability/decreasing cost function. Mice optimized their performance under seconds-long response deadlines when the underlying function was reward probability but approached this level of performance when the underlying function was reward cost, only under the assumption of logarithmically scaled subjective costs. The same subjects were then tested in a timed response inhibition task characterized by response rules that conflicted with the initial task, not responding earlier than a schedule as opposed to not missing the deadline. Irrespective of original test groups, mice optimized the timing of their inhibitory control in the second experiment. These results provide strong support for the ubiquity of optimal temporal risk assessment in mice.     

Cognitive control of a simple mental image in patients with obsessive--compulsive disorder

The nature of obsessions has led researchers to try to determine if the main problem in obsessive-compulsive disorder (OCD) is impaired inhibitory control. Previous studies report that the effort to suppress is one of the factors that increase the frequency of obsessive thoughts. Based on these results and those of the present study that suggest inferior parietal lobe (IPL) abnormality in OCD and findings of a recent study that reported the importance of the right posterior parietal cortex in cognitive control of a simple mental image, the present cognitive control paradigm study aimed to determine whether there is a difference in brain dynamics between OCD patients and non-obsessive controls while performing tasks that necessitate cognitive control of a simple mental image, and whether the right posterior parietal region is one of the regions in which a difference in activity between the OCD patients and controls would be observed. Functional brain imaging was performed while the participants attempted to suppress, imagine, or manipulate a mental image. The general linear model showed that there was a main effect of group and main effect of task. Accordingly, in all contrasts (suppression minus free-imagination, erasing minus free-imagination, and imagination minus free-imagination), the right IPL, right posterior cingulate cortex, and right superior frontal gyrus activity were lower in the OCD patients than in the healthy controls. These results and the observed correlations between activity levels, and symptom and subjective performance scores are discussed. In conclusion, the results of the present study and those of previous studies suggest that the main problem in OCD might be difficulty activating the right frontoparietal networks during tasks that require cognitive control, which might result in the intrusiveness of obsessive thoughts.     

A Systematic Review of the Effectiveness of Self-Compassion-Related Interventions for Individuals With Chronic Physical Health Conditions

Self-compassion, defined as a mindful way of coping with pain and suffering by showing kindness, care, and concern towards the self, may improve psychological adjustment in people living with a chronic physical health condition (CPHC). Various studies illustrate that self-compassion is associated with positive outcomes in general. The aim of this systematic review is to establish the effect of compassion-related therapies on self-compassion specifically in people with CPHCs. Secondary aims are to (a) establish the effect on other psychological and physiological outcomes and (b) explore the relative effectiveness of different therapy types among those identified. Cochrane, Embase, Medline, PsycINFO, and CINAHL databases were searched using “compassion” AND “chronic disease” AND “psychological outcomes” and their synonyms, from 2004 to March 2019. Eligible studies had an experimental design using a self-compassion scale with an adult population. Risk of bias (RoB) was assessed using the Cochrane RoB tool. Effect sizes were calculated for study outcomes. Fifteen studies, including a total of 1,190 participants, 7 different CPHCs, and 11 types of therapies, were included in the review. Nearly all included therapies significantly increased self-compassion with medium to large effect sizes, and reported positive outcomes, such as decreased depression. None of the therapy types appeared clearly superior to the others. Findings from this review show that included therapies increased self-compassion and improved various outcomes, which may represent clinically significant benefits for patients. However, there is a need to further understand how self-compassion exerts its benefits and determine the best methods to increase self-compassion.     

Catastrophizing,Depression and Anxiety During Pregnancy: Relation Between Lumbopelvic Pain and Physical/Social Functioning

Catastrophizing, a cognitive behavioral aspect of pain, is defined as an excessively negative orientation against a noxious stimulus. The primary goal of the present study is to assess the association between catastrophizing and lumbopelvic pain intensity during the pregnancy period, the secondary goal is to explore the variation of pain catastrophizing, anxiety and depression, and the tertiary goal is to investigate the relationship between catastrophizing and quality of life. After approval, pregnant women with lumbopelvic pain were invited to join in the study. During admission, participants were asked to complete questionnaires including Pain Catastrophizing Scale, Beck Anxiety Inventory, Beck Depression Inventory-II, and Short Form-36. Age, gravida, parity, number of abortus, number of live-births and the pain intensity score were recorded. A total of 429 women were enrolled in the study. Pain catastrophizing scores showed a fluctuation during pregnancy, and were significantly correlated with the scores of Beck Anxiety Inventory, Beck Depression Inventory, Visual Analog Scale, and Short Form-36 sub-scales including social functioning, vitality, physical functioning and mental health. The present study demonstrated that catastrophizing level shows an alteration throughout the pregnancy period, and variation in catastrophizing shows an approximately similar course with pain intensity, depression and anxiety.
