Abstract

In this project, using experimental results and computational modeling, we aimed to investigate the influence of gap junctions (GJ) channels on neuronal synchronization and we intend to study the effects of drugs on the attenuation of epileptic seizures. Electrophysiological records, both in vivo and in vitro, of the hippocampus and cortex of healthy rats and pilocarpine-induced status epilepticus(SE) rats will be performed. These results will be analyzed using statistical and modeling tools considering networks of adaptive exponential integrate-and-fire neurons. Firstly, simulations of healthy rat firing patterns will be done, as wellas analyzes of the effects of blocking GJ channels on previously simulated patterns, in order to observe the contribution of these channels in neuronal activity under physiological conditions. Then, similar simulations and analyzes will beperformed based on the neuronal activity observed in the condition of epileptic seizures, in order to verify the contribution of GJ channels in epilepsy. With these analysis we expect the elucidation of mechanisms involved with the generation of epileptic seizures, making possible the development of therapeutic strategies.
