Triarchic Model

Deficits in response to reward and loss are implicated in antisocial personality disorder (ASPD) and psychopathy. This study examined sex differences in associations of neural response to reward and loss with triarchic model traits and ASPD symptoms. Functional neuroimaging data was collected during a monetary incentive delay task from 158 participants. We predicted that males high in ASPD would show greater neural response to reward anticipation and less neural response to loss. Analyses examining the triarchic model were exploratory. A significant sex by Boldness interaction was associated with left nucleus accumbens response during loss anticipation. There were also significant sex by ASPD associations with left nucleus accumbens and left amygdala activation during the loss feedback condition and left nucleus accumbens during loss anticipation. These results demonstrate the importance of considering the effects of sex and triarchic model traits when examining reward and loss processing in the context of antisocial behavior.

Monetary Incentive Delay

Abnormalities in responses to reward and loss are implicated in the etiology of antisocial behavior and psychopathic traits. Although there is evidence for sex differences in neural response to reward and loss, it remains unclear how sex differences may moderate links between these neural responses and the phenotypic expression of antisocial behavior and psychopathic traits. This study examined sex differences in associations of neural response to reward and loss with antisocial personality symptoms and psychopathic traits. Functional neuroimaging data were collected during a monetary incentive delay task from 158 participants. Among males, during loss anticipation, activation in the left nucleus accumbens was negatively associated with antisocial behavior. Among females, during loss feedback, activation in the left nucleus accumbens and left amygdala was negatively associated with antisocial behavior. These results suggest that phenotypic sex differences in psychopathic traits and antisocial behavior may in part be attributable to different etiological pathways.

ZusammenfassungEine Störung des dopaminergen Belohnungssystems bei schizophrenen Patienten wurde wiederholt postuliert. Ein solcher Zusammenhang liegt aufgrund der bei schizophrenen Störungen bekannten dopaminergen Dysfunktion und der klinischen Phänomenologie vor allem der Negativsymptomatik nahe. Der Artikel berichtet die Ergebnisse zweier Studien mit funktioneller Magnetresonanztomografie (fMRT), in denen dieser Zusammenhang untersucht wurde. Es wurden zum einen unmedizierte schizophrene Patienten und zum anderen Patienten unter Behandlung mit typischen und atypischen Neuroleptika sowie gesunde Kontrollen mit einem motivationalen Paradigma (Monetary Incentive Delay Task, MID) untersucht. Im Vergleich zu den gesunden Kontrollpersonen zeigten unbehandelte schizophrene Patienten eine signifikant reduzierte Aktivierung des ventralen Striatums inklusive des Nucleus accumbens, einer Kernregion des Belohnungssystems, bei der Antizipation von Gewinn. Je niedriger die individuelle Aktivierung im ventralen Striatum ausfiel, desto höher war die Negativsymptomatik der unbehandelten Patienten. Ähnlich wie bei unbehandelten Patienten zeigten Patienten mit typischer neuroleptischer Medikation keine signifikante Aktivierung des ventralen Striatums und wiederum eine Assoziation mit der Negativsymptomatik, während Patienten mit atypischer neuroleptischer Medikation eine mäßiggradige Aktivierung des ventralen Striatums aufwiesen, die nicht mit der Schwere der Negativsymptomatik korrelierte. Diese Beobachtungen weisen darauf hin, dass sowohl unbehandelte Patienten wie Patienten mit hochgradiger Blockade der Dopaminrezeptoren durch typische Neuroleptika eine Beeinträchtigung des Belohnungssystems aufweisen. Die Erfassung der direkten Interaktion zwischen der Funktion des Belohungssystems und der dopaminergen Neurotransmission ist Gegenstand laufender Studien.

Abstract Background Men and women show differences in sensitivity to reward and punishment, which may impact behavior in health and disease. However, the neural bases of these sex differences remain under-investigated. Here, by combining functional magnetic resonance imaging (fMRI) and a Monetary Incentive Delay Task (MIDT), we examined sex differences in the neural responses to monetary wins and losses and how these regional activities vary with individual reward and punishment sensitivity. Methods Sixty-three healthy adults (27 women) participated in the fMRI study with a 3-Tesla scanner. Sensitivity to punishment (SP) and sensitivity to reward (SR) were assessed with the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). In the MIDT, participants pressed a button to collect either $1, 1¢, or nil, with the reaction time window titrated across trials to achieve ~67% success. Imaging data were processed with published routines and evaluated with a corrected threshold. Results The results showed higher SP score in women vs. men and higher SR score in men vs. women. Compared to women, men also showed higher response to the receipt of dollar or cent reward in the medial prefrontal cortex, in the area of the supplementary motor cortex. Regional responses to loss did not show sex differences. Further, in a whole-brain regression, activation of the caudate head during 1¢ loss was correlated positively with SR score in men but not in women, and the sex difference was confirmed by a slope test. Conclusions Together, men showed higher SR and neural sensitivity to the receipt of reward, big or small, than women. Individual differences in SR could be reflected by caudate response to a small loss in men. These findings highlight how men and women may differ in reward-related brain activations in the MIDT and add to the imaging literature of sex differences in cognitive and affective functions.

Abstract Background Methamphetamine (METH) use disorder is prevalent worldwide. There are reports of sex differences in quantities of drug used and relapses to drug use among individuals with METH use disorder. However, the molecular neurobiology of these potential sex differences remains unknown. Methods We trained rats to self-administer METH (0. 1 mg/kg/infusion, i.v.) on an fixed-ratio-1 schedule for 20 days using two 3-hour daily METH sessions separated by 30-minute breaks. At the end of self-administration training, rats underwent tests of cue-induced METH seeking on withdrawal days 3 and 30. Twenty-four hours later, nucleus accumbens was dissected and then used to measure neuropeptide mRNA levels. Results Behavioral results show that male rats increased the number of METH infusions earlier during self-administration training and took more METH than females. Both male and female rats could be further divided into 2 phenotypes labeled high and low takers based on the degree of escalation that they exhibited during the course of the METH self-administration experiment. Both males and females exhibited incubation of METH seeking after 30 days of forced withdrawal. Females had higher basal mRNA levels of dynorphin and hypocretin/orexin receptors than males, whereas males expressed higher vasopressin mRNA levels than females under saline and METH conditions. Unexpectedly, only males showed increased expression of nucleus accumbens dynorphin after METH self-administration. Moreover, there were significant correlations between nucleus accumbens Hcrtr1, Hcrtr2, Crhr2, and Avpr1b mRNA levels and cue-induced METH seeking only in female rats. Conclusion Our results identify some behavioral and molecular differences between male and female rats that had self-administered METH. Sexual dimorphism in responses to METH exposure should be considered when developing potential therapeutic agents against METH use disorder.

BackgroundChildhood adversity is associated with significantly increased risk of psychiatric disorder. To date, functional magnetic resonance imaging (fMRI) studies of children have mainly focused on institutionalisation and investigated conscious processing of affect.AimsTo investigate neural response to pre-attentively presented affect cues in a community sample of children with documented experiences of maltreatment in the home.MethodA masked dot-probe paradigm involving pre-attentive presentation of angry, happy and neutral facial expressions was employed. Eighteen maltreated children were compared with 23 carefully matched non-maltreated peers.ResultsIncreased neural response was observed in the right amygdala for pre-attentively presented angry and happy faces in maltreated v. non-maltreated children. Level of amygdala activation was negatively associated with age at onset for several abuse subtypes.ConclusionsMaltreatment is associated with heightened neural response to positive and negative facial affect, even to stimuli outside awareness. This may represent a latent neural risk factor for future psychiatric disorder.

IntroductionDeep brain stimulation (DBS) is a promising therapy option for otherwise treatment-resistant neuropsychiatrie disorders, especially in obsessive-compulsive disorder (OCD), major depression (TRD) and Tourette's Syndrome (TS).ObjectiveThe brain coordinates of the DBS targets are mainly reported using measurements in original, unnormalized brains. In the neuroimaging community stereotactic data are mainly indicated in the standardized Montreal Neurological Institute (MNI) space, i.e. a three-dimensional proportional grid system.AimsImproved comparability between targets in DBS studies and molecular and functional neuroimaging data from PET, SPECT, MRI, fMRI, mostly published with stereotactic data.MethodsA comprehensive and systematic literature search for published DBS case reports or studies in TRD, OCD and TS was performed. We extracted the tip positions of electrode leads as provided in the publications or by the authors, and transferred individual coordinates to the standard brain in the MNI space.Results46 publications fulfilled the inclusion criteria. The main targets for the specific disorders and one or two examples of their calculated MNI coordinates are indicated in the table:[MNI coordinates of the main DBS targets]ConclusionsWe provide DBS data of neuropsychiatrie disorders in the MNI space, improving the comparability to molecular, functional and structural neuroimaging data.

Functional imaging has become a primary tool in the study of human psychology but is not without its detractors. Although cognitive neuroscientists have made great strides in understanding the neural instantiation of countless cognitive processes, commentators have sometimes argued that functional imaging provides little or no utility for psychologists. And indeed, myriad studies over the last quarter century have employed the technique of brain mapping—identifying the neural correlates of various psychological phenomena—in ways that bear minimally on psychological theory. How can brain mapping be made more relevant to behavioral scientists broadly? Here, we describe three trends that increase precisely this relevance: (i) the use of neuroimaging data to adjudicate between competing psychological theories through forward inference, (ii) isolating neural markers of information processing steps to better understand complex tasks and psychological phenomena through probabilistic reverse inference, and (iii) using brain activity to predict subsequent behavior. Critically, these new approaches build on the extensive tradition of brain mapping, suggesting that efforts in this area—although not initially maximally relevant to psychology—can indeed be used in ways that constrain and advance psychological theory.
