The role of dorsomedial striatum and parvalbumin interneurons in schizophrenia-related cognitive deficits: insights from disrupted strategic decision-making in Akt1 heterozygous mice.

ABSTRACT: Schizophrenia, a debilitating disorder with genetic and neurobiological underpinnings, often manifests cognitive deficits, including impaired decision-making. Utilizing Akt1 heterozygous mutant (HET) mice as a model, which mimic schizophrenia due to AKT1's implication as a susceptibility gene, we investigated the involvement of Akt1 and its neural mechanisms influencing strategic decision-making to identify potential therapeutic targets for schizophrenia-associated cognitive impairments. In six experiments, we first revealed that lesions targeting the dorsomedial striatum (DMS) significantly impacted performance in a mouse version of the two-choice probabilistic decision-making task, surpassing effects observed in other striatal subregions. Behavioral assessments in HET mice unveiled notab
