Multimodal assessments were performed pre\u2010 and post\u2010intervention, including structural and functional MRI for analysing grey matter volume (GMV), fractional amplitude of low\u2010frequency fluctuations (fALFF), and regional homogeneity (ReHo). Cognitive function was evaluated using standardized computerized tasks (the Flanker and N\u2010back). Additionally, comprehensive metabolic profiles were assessed, including markers of glucose and lipid metabolism along with inflammatory cells.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Semaglutide treatment significantly improved systemic metabolic health, inducing weight loss and reducing glycolipid levels and leukocyte counts. Neuroimaging revealed targeted neurobiological effects in the left temporal lobe: specifically, increased GMV in the left inferior temporal gyrus and decreased fALFF in the left middle and superior temporal gyri alongside reduced ReHo in the left middle temporal gyrus. These neural changes occurred despite no significant improvement in cognitive task performance. Importantly, the alterations in brain structure and function were not statistically correlated with the degree of weight loss or metabolic improvement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A 24\u2010week semaglutide intervention induces significant neurobiological remodelling in the left temporal lobe of adults with overweight or obesity.
