Neuroscience Pentylenetetrazole-Induced Kindling Mouse Model Tadayuki Shimada1, Kanato Yamagata1 1Synaptic Plasticity Project, Tokyo Metropolitan Institute of Medical Science This protocol describes a method of chemical kindling with pentylenetetrazole and provides a mouse model of epilepsy. This protocol can also be used to investigate vulnerability to seizure induction and pathogenesis after epileptic seizures in mice.
