Abstract:
:Intracerebroventricular (i.c.v.) injection of rat corticotropin-releasing factor (rCRF) at doses of 5-20 micrograms in rats induces epileptogenic activity characterized by pacemaker-like spikes localized in the hippocampal leads. Such an effect was still present in rats neonatally treated with saline but was absent in those neonatally treated with monosodium glutamate (MSG), a treatment that caused marked changes in the concentration of several brain neurotransmitters and neuropeptides in hypothalamic nuclei where CRF is highly concentrated and is believed to induce endocrinologic and behavioral effects. The present results suggest the rCRF-induced spiking activity is mediated by activation of neuronal pathways sensitive to MSG neurotoxic effect.

EPILEPSIA文献大全abstract::More than 28,000 neuroscientists and 3,000 epileptologists gathered at their respective 2001 meetings of the Society for Neuroscience and the American Epilepsy Society. Yet only six articles, one directly and five indirectly, discussed the corpus callosum (CC). Is not this in itself a remarkable finding? Are there no ...
