简介：
Overview
This article discusses the preparation of sex-stratified primary dissociated neuronal cultures from embryonic hippocampal tissue. By sexing embryos prior to isolation, researchers can create separate male and female cultures, facilitating the study of sex-specific signaling mechanisms in neuron death.
