Summary: There is a consensus that circuits in the prefrontal and anterior cingulate cortex play a critical role in reward-based decision making. The functional specialization of PFC/ACC circuits in humans and primates involve microcircuits that support persistent activity during cognitive tasks and macrocircuit connections that vary between different cytoarchitectonic subregions, contributing uniquely to reward-based decision tasks. This variation in circuit connections predicts distinctive neural representations in different regions of the brain during sequential attention-guided choice.

Summary: This study aimed to investigate the efficacy of adjunctive NAC in improving negative symptoms, cognition, and quality of life in treatment-resistant schizophrenia patients on clozapine treatment. The results showed that NAC did not significantly improve symptoms, cognition, or quality of life over a 1-year period compared to placebo, and there were no significant differences in reported side effects between the groups.

Summary: This article presents a systematic review of the role of affect and cognition in managerial decision making, based on the recent cross-fertilization of management studies with neuroscience. The results support the emerging unified mind processing theory, where affective states play a driving role towards cognition in decision making. A research agenda for future studies in this area is also provided.

Summary: The study suggests that psychopathic traits are associated with a reduced tendency to cooperate and no difference in considering others' retaliation possibilities. However, the context in which economic decision-making games are employed moderates the relationship between psychopathy and total gain obtained.

Summary: Shared decision making (SDM) is not widely used in mental health due to inconsistent definitions, models, measurement tools, and lack of evidence for its effectiveness. This study aims to analyze the global development trends and challenges of SDM research, clarify the meaning and measurement of SDM in mental health, and create a theoretical framework for effective SDM components. The current landscape of SDM in mental health is disconnected from the needs and experiences of potential end-users, and the SDM-MH framework expands its scope and offers potential target outcomes to reduce heterogeneity.

Ethics

Summary: The evaluation of patients' decision-making capacity presents an ethical dilemma for psychiatrists as patients may not be aware their capacity is being assessed. Ethical practice requires patients to be informed about the assessment, but this may lead to negative reactions and hinder therapeutic engagement. Systemic initiatives are needed for universal awareness of patients about the assessment of their capacity in healthcare systems.

Summary: The results of three studies suggest that there is no consistent relationship between testosterone and financial behavior or preferences. Although significant effects were found in specific cases, these findings did not replicate in other studies or would not remain significant when controlling for family-wise error rate. Potential contextual moderators that may determine under what circumstances testosterone affects economic decision making are considered.

Summary: Neuroeconomics emerged as a new scientific field in the late 1990s, benefiting from converging trends in economics, psychology, and neuroscience, as well as the availability of experimental designs and advances in understanding brain functioning. The paper explores the emo-rational brain, social brain, and computational brain as three main topics in neuroeconomics, emphasizing critical findings for its birth and development. It also highlights the porous boundaries between neuroeconomics and recent sub-fields of cognitive neuroscience.

Summary: The study found that European psychiatrists prefer shared clinical decision-making style, with significant differences in non-SDM decision-making styles. The importance of dialogue and educational efforts to harmonize clinical practice across Europe was emphasized.

Summary: Cognitive impairment is related to both white matter macrostructure and microstructure in bipolar disorder patients. However, there is inconsistency in the results of the studies examining this relationship. Some studies have found an association between higher fractional anisotropy in white matter and better complex attention skills and executive functioning in bipolar disorder patients, while others have found no associations. Further research with increased statistical power and standardized methods is needed.

Summary: In recent years, pigs have gained attention as an important model animal for studying human neuroanatomy, physiology, and behavior. Their high intelligence and ability to perform various behaviors make them valuable in understanding neurological conditions. Pigs have particularly emerged as a relevant species for studying traumatic brain injury. The use of pigs in cognitive and behavioral research, as well as physiological assessment, is discussed in this review.

Summary: In this study, latent class analysis (LCA) was used to identify different typologies of patient preferences for involvement in the decision-making process in mental healthcare settings. Three distinct preference typologies were identified, accounting for 78% of the variance. These findings highlight the variations in psychiatric patients' preferences for treatment involvement based on demographic variables and health status, offering valuable insights for mental healthcare research.

Summary: Tourette syndrome (TS) and its comorbidities are associated with risky behavior, but it is unclear if this translates to a general attitude towards risk. This study found that impaired evaluation of risk and ambiguity in TS was not related to TS itself, but rather to the presence of comorbidities.

Summary: Expected Utility Theory describes choices as a process of maximizing utility, where decision makers assign subjective value to each choice option and select the one with the highest utility. The continuity axiom is central to the theory, requiring decision makers to be indifferent between different gambles, which is crucial for defining numerical utilities.

Summary: Human social behavior crucially depends on our ability to reason about others, and theory of mind plays a vital role in social cognition by helping us understand hidden thoughts and beliefs of others. Although brain regions linked to social reasoning have been identified, the basic cellular mechanisms underlying theory of mind remain undefined.

Summary: Competitive interactions play a vital role in the ecology of animal species and strongly influence group behavior. Researchers have discovered neurons in the anterior cingulate that adaptively represent the social rank of animals and influence their decision-making. These neurons can track other individuals within a group and accurately predict future success. The application of neuromodulation techniques also reveals that these neurons conditionally influence competitive effort.
