Protocol to Induce Neurodegeneration in a Local Area Of the Mouse Brain by Stereotaxic Injection

In vivo models of brain pathology are crucial for studying neurological diseases. Here, we present a protocol to induce a pathological condition in a mouse brain area by local injection of neurotoxic stimulus. We describe steps for preparing reagents, stereotaxic injection procedures to induce neurodegeneration in the hippocampus, and preparation of brain sections to examine the induced model. This protocol is useful for studying how local pathology affects other brain areas and neighbor cells and its functional consequences in behavior. For complete details on the use and execution of this protocol, please refer to Zhang et al..
