We aimed to develop and validate a reliable method for stable long-term recordings of EEG activity in zebrafish, which is less prone to artifacts than current invasive techniques. EEG activity was recorded with a blunt electrolyte-filled glass pipette placed on the zebrafish head mimicking surface EEG technology in man. In addition, paralysis of agarose-embedded fish using D-tubocurarine exclud...

The effect of the nootropic drug piracetam (100 mg/kg) on kindled seizures, kindling-induced learning deficits, and histological alterations due to changes in central excitability was investigated in Wistar rats. The animals were kindled by repeated i.p. injections of an initially subconvulsive dose of pentylenetetrazol (PTZ). As a control, piracetam or physiological saline was given 60 minutes...

BACKGROUND It has been reported that epilepsy is a disorder of the central nervous system that causes memory impairment. This study examines the role of the aqueous extract of Boswellia on the learning disability of the pentylenetetrazol (PTZ)-induced kindled rats. METHODS In this experimental study, 64 male rats were used. Kindling seizures were induced by three injections of 25 mg/kg of PTZ...

PURPOSE 2-Deoxy-D-glucose (2-DG), a glucose analog that accumulates in cells and interferes with carbohydrate metabolism by inhibiting glycolytic enzymes, has anticonvulsant actions. Recognizing that severe glucose deprivation can induce seizures, we sought to determine whether acute treatment with 2-DG can promote seizure susceptibility by assessing its effects on seizure threshold. For compar...

OBJECTIVE To evaluate the aqueous extract from aerial parts of Artemisia copa Phil. (Asteraceae) administered orallyfor its psychopharmacological activities in several experimental models. METHODS The extract was administered p.o. in Swiss albino mice and tested on pentobarbital-induced hypnosis, locomotor activity, exploration in the hole-board, anxiolytic like profile evaluated in the marbl...
