Protocol for the culturing of primary hippocampal mouse neurons for functional in vitro studies.

Primary hippocampal cultures grown from genetically modified mice provide a simplified context to study molecular mechanisms underlying neuronal development, synaptogenesis, and synapse plasticity in vitro. Here, we describe a simple protocol for culturing hippocampal neurons from P0 to P2 mice and a strategy for inducing alterations in synaptic strength at inhibitory and excitatory synapses in vitro. We also describe approaches for immunofluorescent labeling, image acquisition, and quantification of synaptic proteins. For complete details on the use and execution of this protocol, please refer to Cramer et al..
