In Drosophila, the protocerebral anterior medial (PAM) cluster dopamine neurons mediate reward signals. Here, we show that localized inhibitory input to the presynaptic terminals of the PAM neurons titrates olfactory reward memory and controls memory specificity. The inhibitory regulation was mediated by metabotropic gamma-aminobutyric acid (GABA) receptors clustered in presynaptic microdomain of the PAM boutons. Cell type-specific silencing the GABA receptors enhanced memory by augmenting internal reward signals. Strikingly, the disruption of GABA signaling reduced memory specificity to the rewarded odor by changing local odor representations in the presynaptic terminals of the PAM neurons. The inhibitory microcircuit of the dopamine neurons is thus crucial for both reward values and memory specificity. Maladaptive presynaptic regulation causes optimistic cognitive bias.Etuaptmumk or Two-Eyed Seeing (E/TES) is foundational in ensuring that Indigenous ways of knowing are respected, honoured, and acknowledged in health research practices with Indigenous Peoples of Canada. This paper will outline new knowledge gleaned from the Canadian Institute of Health Research and Chronic Pain Network funded Aboriginal Children's Hurt & Healing (ACHH) Initiative that embraces E/TES for respectful research. We share the ACHH exemplar to show how Indigenous community partners take the lead to address their health priorities by integrating cultural values of kinship and interconnectedness as essential components to enhance the process of community-led research. E/TES is conceptualised into eight essential considerations to know in conducting Indigenous health research shared from a L'nuwey (Mi'kmaw) perspective. L'nu knowledge underscores the importance of working from an Indigenous perspective or specifically from a L'nu
