Abstract
The Metabolic Syndrome (MS) is a set of alterations that increase the risk of developing type 2 diabetes mellitus (DM2). There is evidence that obesity and the development of metabolic syndrome lead to alterations in cognitive processes. In this work it was proposed to determine if generating the metabolic syndrome produces changes in the electric unitary spontaneous activity in the hippocampus as a possible sustain of the learning alterations. In Wistar rat with a hypercaloric diet, metabolic syndrome was provoked, and this was confirmed with the determination of body and metabolic parameters as a measure of intraperitoneal fat, glucose, triglycerides, and cholesterol. Electrophysiological records were made in the hippocampus and it was determined that rats treated with a hypercaloric diet show a significant decrease in such activity. Thus, it is shown that rats that were caused metabolic syndrome, alter their hippocampal electrophysiological activity.
