   This study explores the role of the Wnt pathway in regulating dendritic spine morphology and synaptic function. The authors found that activation of the Wnt pathway leads to the formation of new spines and enhances synaptic strength. Their findings suggest a novel mechanism by which the Wnt pathway influences synaptic plasticity and cognitive function.
