A new study identifies enhanced excitatory synaptic transmission onto glutamatergic neurons in the basolateral amygdala as a potential mechanism driving aging-related increases in innate anxiety-like behaviors in male mice. Researchers demonstrated that this synaptic strengthening specifically within the basolateral amygdala circuit correlates with heightened anxiety states observed in aged animals. For a neuroscientist investigating placebo analgesia and chronic pain at the Brain and Mind Centre, understanding how age-related circuit-level changes in the amygdala contribute to affective disorders is directly relevant, as these mechanisms may interact with pain processing and placebo responses in aging populations.
