Juxtasomal Biocytin Labeling to Study the Structure-function Relationship of Individual Cortical Neurons

To understand the structure of neuronal networks, functional and morphological characterization of individual neurons is a necessity. Here, we demonstrate juxtasomal biocytin labeling, which allows electrophysiological recordings in the extracellular configuration, yet maintaining the ability to intracellularly label the neuron for post hoc reconstruction of dendritic and axonal architecture
