title: Regional difference in depolarization-elicited accumulation of cyclic AMP in cobalt-induced epileptic cortex of the rat.
abstract: The appearance of epileptiform discharges in electrocorticograms was induced by a unilateral injection of CoCl2 solution into the sensorimotor cortex of rats. Accumulation of cyclic AMP elicited by ouabain or a high concentration of potassium ions was determined in slices from different cortical areas of rats 9 or 10 days after the injection. In the anterior cortex, the depolarization-elicited accumulation of cyclic AMP was significantly higher in the cortical area ipsilateral to the injection site than in the contralateral cortical area. In the posterior cortex, a similar but not significant difference in the accumulation of cyclic AMP was noted.
