The article "Balancing Structure and Function at Hippocampal Dendritic Spines" by Jennifer N. Bourne and Kristen M. Harris reviews the structural and functional plasticity of dendritic spines in the hippocampus. Dendritic spines are crucial for local signaling at synapses and undergo structural changes in response to synaptic activity, developmental stages, and environmental factors. The authors discuss the molecular mechanisms that regulate spine structure, including actin dynamics, protein synthesis, and the involvement of astroglia. They highlight the importance of imaging techniques, such as serial section transmission electron microscopy (ssTEM), in understanding the fine details of spine structure. The review also explores the role of adhesion molecules and trans-synaptic signaling in spine formation and stabilization, and the impact of these processes on synaptic plasticity. The authors conclude by emphasizing the need for further research to fully understand the complex interactions that govern dendritic spine development and function.The article "Balancing Structure and Function at Hippocampal Dendritic Spines" by Jennifer N.
