Denne protokol beskriver opførelsen af et billigt mikroinjektionssystem, dets stereotaxiske implantation i dybhjernestrukturer og proceduren for tidsurige mikroinjektioner af tetrodotoksin hos vågne og hæmningsløse rotter. Målet er at afsløre deltagelsen af hypothalamus strukturer i reguleringen af ægløsning ved at hæmme deres neurale aktivitet.
