Embelin also exhibited significant and dose dependant delayed onset of clonic-tonic actions and protection from PTZ induced mortality and may be interfering with GABAergic mechanism to exert its anticonvulsant effect (Gale 1992).
We expect this to be the first of many discoveries by Neuralstem of key fate-determining factors that will enable controlled differentiation of neural stem cells into specific types of neurons, such as dopamine-producing neurons, acetylcholine-producing neurons, and GABAergic neurons," said Richard Garr, President and CEO of Neuralstem.
