There are increasing studies indicating neuroprotective effects for vitamin B12. In the present study, the effect of intracortical microinjection of vitamin B12 was investigated on penicillin-induced epileptiform activity. We also examined the effects of intracortical microinjection of diazepam (a GABA-benzodiazepine receptor agonist) and flumazenil (a GABAbenzodiazepine receptor antagonist) to...
