First paper accepted: “Optogenetic and chemogenetic manipulation of seizure threshold in mice”
Dec 24, 2022 - First paper accepted: “Optogenetic and chemogenetic manipulation of seizure threshold in mice”
We were thrilled to learn that the Mattis lab's first paper has been accepted for publication in STAR Protocols! In this paper, we detail a protocol for the use of optogenetics or chemogenetics to assess the neuronal circuits contributing to seizure initiation, with a focus on hyperthermia-induced seizures. Congratulations to first author Julia Kravchenko!
