Section of the nervi corporis cardiaci I and provoked release of median gonadotropic factor in the African locust


The in vivo electrostimulation of the pars inercerebralis of Locusta migratoria, after cutting the nervi corporis cardiaci I, does not provoke the release of the gonadotropic hormone from the cell bodies. The provoked release of the gonadotropic hormone recommences soon as the axon terminals are regenerated (reentry of the nerves into the original corpora cardiaca for all the histological controls). The electrostimulation of the pars intercerebralis seems to favour the bilateral reentry of the nerves into the corpora cardiaca.
