It has been shown that gamma-aminobutyric acid (GABA) is densely packed in the inner nuclear and plexiform layers in the rat retina, where it is mainly located within a subgroup of amacrine cells. This study examined the effects on the electroretinogram of GABA antagonists infused into the vitreous
1. In rats anaesthetized with pentobarbitone sodium, a unilateral acute arthritis was produced by the injection of kaolin and carrageenan into one knee-joint cavity. Four hours after injection, the medial articular nerve (MAN) was sectioned distally and recordings obtained from the proximal stump of
Using multibarrel electrodes, recordings were made in the cortical taste area (CTA), specifically in the granular and dysgranular parts of the insular cortex (areas GI and DI), of urethane-anesthetized rats. The effects of an iontophoretic application of gamma-aminobutylic acid (GABA) and
We examined the effects of caloric vestibular stimulation on the neuronal activity of the locus coeruleus (LC) in urethane-anesthetized rats. The middle ear cavity was irrigated with hot (44 degrees C) or cold (30 degrees C) water through a polyethylene tube. Most neurons (hot water: 76%, 55/72;
Rhythmical jaw movements (RJM) were induced by stimulation of the cerebral peduncle or the oral cavity in the anesthetized rat and iontophoretic application of glutamate was examined on each reticular neuron with phase-dependent rhythmical activity during RJM (RJM-phasic neuron). Glutamate activated
Neurocysticercosis, caused by Taenia solium, is a common cause of neurologic disease in developing countries and among immigrants to the United States. Seizures are the most common clinical manifestation of neurocysticercosis. Imaging studies of patients with seizures from neurocysticercosis
