Abstract Behavioral studies found evidence for superior cognitive empathy (CE) in pedophilic men without a history of child sexual offending (P-CSO) compared to pedophilic men with a history of CSO (P+CSO). Functional magnetic resonance imaging (fMRI) studies also point to differences between P-CSO and P+CSO. Neural processing associated with CE has not yet been investigated. Therefore, the present study aimed to explore the neural correlates of CE in subjects with pedophilia with (P+CSO) and without (P-CSO) child sexual offending. 15 P+CSO, 15 P-CSO, and 24 teleiophilic male controls (TC) performed a CE task during fMRI. We observed reduced activation in the left precuneus (Pcu) and increased activation in the left anterior cingulate cortex (ACC) in P-CSO compared to P+CSO. P-CSO also showed stronger connectivity between these regions, which might reflect a top-down modulation of the Pcu by the ACC toward an increased self-focused emotional reaction in social situations. There was also evidence for increased right superior temporal gyrus activation in P-CSO that might constitute a potentially compensatory recruitment due to the dampened Pcu activation. These findings provide first evidence for altered neural processing of CE in P-CSO and underline the importance of addressing CE in pedophilia and CSO in order to uncover processes relevant to effective prevention of child sexual abuse.

BackgroundThe neurocognitive basis of auditory verbal hallucinations is unclear.AimsTo investigate whether people with a history of such hallucinations would misattribute their own speech as external and show differential activation in brain areas implicated in hallucinations compared with people without such hallucinations.MethodParticipants underwent functional magnetic resonance imaging (fMRI) while listening to pre-recorded words. The source (self/non-self) and acoustic quality (undistorted/distorted) were varied across trials. Participants indicated whether the speech they heard was their own or that of another person. Twenty people with schizophrenia (auditory verbal hallucinations n=10, no hallucinations n=10) and healthy controls (n=11) were tested.ResultsThe hallucinator group made more external misattributions and showed altered activation in the superior temporal gyrus and anterior cingulate compared with both other groups.ConclusionsThe misidentification of self-generated speech in patients with auditory verbal hallucinations is associated with functional abnormalities in the anterior cingulate and left temporal cortex. This may be related to impairment in the explicit evaluation of ambiguous auditory verbal stimuli.

The urgent need to recognize danger quickly has been shown to rely on preferential processing in dedicated neural circuitry. In previous behavioral studies examining the pattern of the face when displaying anger, we found evidence that simple noncontextual geometric shapes containing downward-pointing V-shaped angles activate the perception of threat. We here report that the neural circuitry known to be mobilized by many realistic, contextual threatening displays is also triggered by the simplest form of this V-shaped movement pattern, a downward-pointing triangle. Specifically, we show that simple geometric forms containing only downward-pointing V-shapes elicit greater activation of the amygdala, subgenual anterior cingulate cortex, superior temporal gyrus, and fusiform gyrus, as well as extrastriate visual regions, than do presentations of the identical V-shape pointing upward. Thus, this simple V-shape is capable of activating neural networks instantiating detection of threat and negative affect, suggesting that recognition of potential danger may be based, in part, on very simple, context-free visual cues.

Individuals with alcohol use disorder (AUD) show elevated brain metabolism of acetate at the expense of glucose. We hypothesized that a shift in energy substrates during withdrawal may contribute to withdrawal severity and neurotoxicity in AUD and that a ketogenic diet (KD) may mitigate these effects. We found that inpatients with AUD randomized to receive KD (n = 19) required fewer benzodiazepines during the first week of detoxification, in comparison to those receiving a standard American (SA) diet (n = 14). Over a 3-week treatment, KD compared to SA showed lower “wanting” and increased dorsal anterior cingulate cortex (dACC) reactivity to alcohol cues and altered dACC bioenergetics (i.e., elevated ketones and glutamate and lower neuroinflammatory markers). In a rat model of alcohol dependence, a history of KD reduced alcohol consumption. We provide clinical and preclinical evidence for beneficial effects of KD on managing alcohol withdrawal and on reducing alcohol drinking.

AbstractBrain blood vessels constitute a micrometer-scale vascular network responsible for supply of oxygen and nutrition. In this study, we analyzed cerebral tissues of the anterior cingulate cortex and superior temporal gyrus of schizophrenia cases and age/gender-matched controls by using synchrotron radiation microtomography or micro-CT in order to examine the three-dimensional structure of cerebral vessels. Over 1 m of cerebral blood vessels was traced to build Cartesian-coordinate models, which were then used for calculating structural parameters including the diameter and curvature of the vessels. The distribution of vessel outer diameters showed a peak at 7–9 μm, corresponding to the diameter of the capillaries. Mean curvatures of the capillary vessels showed a significant correlation to the mean curvatures of neurites, while the mean capillary diameter was almost constant, independent of the cases. Our previous studies indicated that the neurites of schizophrenia cases are thin and tortuous compared to controls. The curved capillaries with a constant diameter should occupy a nearly constant volume, while neurons suffering from neurite thinning should have reduced volumes, resulting in a volumetric imbalance between the neurons and the vessels. We suggest that the observed structural correlation between neurons and blood vessels is related to neurovascular abnormalities in schizophrenia.

The article explores the idea of ‘offender-centric’ policing in cases of rape, with its focus on suspect and offender admissions and behaviours. It features discussion of 11 cases, illustrating offender-centric pathways to charge or conviction, the challenges facing complainants, suspects and police officers, along with missed opportunities to focus on a suspect’s behaviour. The importance of victim care and support is discussed, and it is argued that victim care should accompany an offender-centric approach to rape investigation. It is also argued that there are potential dangers with offender-centric tactics, specifically, that without due care it may become a self-confirming investigative tool influenced by confirmation bias which may lead to flawed decision-making. The article concludes by arguing that offender-centric policing has benefits in those cases with suspects who engage in predatory behaviour, have a history of previously undisclosed sexual offending and domestic violence and other problematic behaviours. It also has value in focusing the attention of investigators on what steps were taken by a suspect to ascertain the complainant’s consent. While the offender-centric approach cannot address all investigative challenges in rape cases, it is a useful addition to existing strategies.

Abstract Background Auditory hallucinations have been linked to aberrant functioning of the left superior temporal gyrus (STG) and are associated with impaired cognitive control regulated by areas in the prefrontal cortex. However, the mechanisms behind these dysfunctions are still unclear. Methods The current study combined resting state connectivity fMRI with MR spectroscopy (MRS) in a sample of 81 psychosis patients to explore how neurochemical correlates of auditory hallucinations modulate left STG functioning. The analyses were focused on glutamate (Glu) and gamma-aminobutyric acid (GABA), two neurotransmitters with excitatory and inhibitory functions, respectively, since these have previously been implicated in psychosis. Results Glu and GABA showed differential relationships with left STG connectivity in patients with and without hallucinations. Specifically, Glu concentration in the anterior cingulate cortex (ACC) was positively related to functional connectivity between the left and right temporal lobe in hallucinating patients only. In contrast, GABA concentration in the ACC was negatively related to connectivity between the left and right temporal lobe in non-hallucinating patients only. Discussion These findings support a recently proposed model of interhemispheric temporal lobe miscommunication in auditory hallucinations and indicate prefrontal neurochemical modulation as a potential underlying mechanism. The results can further be integrated with previously suggested excitatory/inhibitory imbalances as neurochemical modulators in AVH.

Sensory sensitivities occur in up to 90% of autistic individuals. With the recent inclusion of sensory symptoms in the diagnostic criteria for autism, there is a current need to develop neural hypotheses related to autistic sensory perception. Using activation likelihood estimation (ALE), we meta-analysed 52 task-based fMRI studies investigating differences between autistic (n=891) and control (n=967) participants during non-social sensory perception. During complex perception, autistic groups showed more activity in the secondary somatosensory and occipital cortices, insula, caudate, superior temporal gyrus, and inferior parietal lobule, while control groups showed more activity in the frontal and parietal regions. During basic sensory processing, autistic groups showed hyperactivity in the lateral occipital cortex, primary somatosensory and motor cortices, insula, caudate, and thalamus, while controls showed heightened activity in the precentral gyrus, middle frontal gyrus, precuneus, and anterior cingulate cortex. We conclude that autistic individuals, on average, show distinct engagement of sensory-related brain networks during sensory perception. These findings may help guide future research to focus on relevant neurobiological mechanisms underpinning the autistic experience.

Friendship, a mutual and profound relationship, permeates history of human culture and occurs in all social situations, including professional and informal human activities. In organizations, it devel­ops through processes of communication and generates a communication culture of kindness and support. Organizational friendship enhances work engagement and satisfaction, as well as helps to promote individual ends. This article investigates the more vital significance of friendship in alter­native organizations. Such organizations, operating at the margins of the currently dominant profit-oriented business model, offer a plethora of insights of possible structures and practices. Our ethno­graphic qualitative research shows the implications of workplace friendship as organizing principle. It helps to make organizations more humane, and redressed the moral imbalance, so prevalent in contemporary organizing and management. This has important implications for any kind of com­munication, creating social awareness around important themes related to management and organ­izations. Patterns of friendship are meaningful for organizing and organizations and their most vi­tal significance concerns the area of social communication.

Keroncong merupakan musik, instrumen musik, dan genre yang diklaim sebagai warisan budaya indonesia. Keroncong sebagai warisan budaya tentunya memiliki sejarah yang panjang.sejarah yang panjang juga tidak akan luput dari pasang surut dan perkembangan. Pasang surut dan perkembangan umumnya dipengaruhi politik dan situasi sosial. Untuk memetakan sejarah keroncong di Indonesia yang diwarnai politik dan situasi sosial, data dikumpulkan melalui dokumentasi, telaah pustaka, dan wawancara. Data valid dikonfirmasi dan dipaparkan secara kronologis berdasar periodesasinya. Hasil penelitian ini menunjukkan bahwa keroncong bermula dari diseminasi instrumen musik bangsa Portugis yang menjalin hubungan dengan Majapahit. Diseminasi instrumen fado di nusantara mengalami perubahan morfologi dan teknik perlakuan alatnya. Perubahan morfologi dan perlakuan alat ini melahirkan instrumen keroncong atau cukulele. Gaya lirik dibangun oleh kearifan lokal nusantara sesuai demografi dan situasi sosial di masing-masing lokasi penciptaannya. Gaya lirik dan pasang surut popularitas keroncong sebagai kelompok musik didorong dan dihentikan oleh naik turunnya kekuatan politik Portugis, Majapahit, Belanda, Jepang, dan Orde Lama dan Orde Baru. Political and Social Situations in the History of Keroncong in IndonesiaAbstract:Keroncong is music, musical instrument, and the genre that is claimed to be Indonesia's cultural heritage. Keroncong, as a cultural heritage, certainly has a long history. A long history will not escape its ups and downs and developments. Political and social situations generally influence the ups and downs and developments. In order to map the history of keroncong in Indonesia, which is colored by politics and social situations, data is collected through documentation, literature review, and interviews. Valid data are confirmed and presented chronologically based on the periodization. The results of this study indicate that keroncong originated from the dissemination of Portuguese musical instruments, which had a relationship with Majapahit. The dissemination of fado instruments in the archipelago has changed the morphology and treatment techniques of the tools. Changes in the morphology and treatment of this tool gave birth to the keroncong or Cukulele instrument. The local wisdom of the archipelago builds the lyric style according to the demographics and social situations in each location of its creation. The lyric style and the ebb and flow of keroncong's popularity as a musical group was driven and stopped by the ups and downs of the political power of the Portuguese, Majapahit, Dutch, Japanese, and the Old and New Order.
