Quantificação da coluna dendrítica usando um software automático de reconstrução tridimensional de neurônios

Overview

This study focuses on the structural profile of dendritic spines in the hippocampus, targeting the CA-one apical dendrite. It aims to address how diverse inputs to different regions of the same dendrite are encoded at the cellular level. The protocol presented balances the need for high-resolution images with reliable, less burdensome spine analysis.
