The rational decision-making model contends that cooperation is the best strategy for maximizing benefits in an iterative prisoner’s dilemma.

In this study, we used functional magnetic resonance imaging to study underlying neural differences in brain regions related to fairness when people interact with an opponent who tend to cooperate or betray, at different decision-making stages. Results based on 40 university students (25 women) indicate that experiences of cooperation or betrayal affect people’s fairness perception. Distinct neural activities occur in expectation, decision, and outcome phases of decisions. In the expectation phase, those in the cooperative condition exhibited increased activation in the anterior cingulate gyrus, medial superior frontal gyrus, and caudate nucleus compared to those in the uncooperative condition. During the decision phase, those in the cooperative condition showed greater activation in the middle frontal gyrus, caudate nucleus/frontal insula, inferior frontal gyrus, and cingulate gyrus compared to those in the uncooperative condition. In the outcome feedback phase, the caudate nucleus, insula, cingulate gyrus, and inferior frontal gyrus of the orbit were more active in the uncooperative condition than in the cooperative condition.

This study explored the potential therapeutic role of famotidine, a histamine (H2) receptor antagonist, as a glycogen synthase kinase-3β (GSK-3β) inhibitor in the context of AD induced by aluminium chloride (AlCl₃) in a rat model. The intricate relationship between GSK-3β dysregulation and AD pathogenesis, particularly in amyloid-β (Aβ) production, formed the basis for investigating famotidine's efficacy. Molecular modelling revealed famotidine's efficient binding to GSK-3β, suggesting inhibitory potential. In behavioural assessments, famotidine-treated groups exhibited dose-dependent improvements in Morris Water Maze, Novel Object Recognition, and Y-Maze tests, comparable to the standard Rivastigmine tartrate group. Biochemical analyses showed that famotidine inhibits acetylcholinesterase, decreases lipid peroxidation, increases antioxidant activity, and mitigates oxidative stress. Moreover, famotidine significantly lowered the levels of GSK-3β, IL-6, and Aβ(1−42). The neuroprotective effects of famotidine were further supported by histopathological analysis. This comprehensive investigation underscores famotidine's potential as a GSK-3β inhibitor, providing insights into its therapeutic impact on AD induced by AlCl₃.
