Aging is one of major risk factor for neurodegenerative disorders. Understanding the normal and healthy aging is still under progress. The analysis of brain field potentials recordedas electroencephalogram (EEG) has been proven to be one of the sensitive tools to characterize brain aging. In the present study, we examined the EEG pattern of young (4 months) and oldwistar rats (24 months old) for beta and theta wave pattern in frontal and parietal cortical lobesand also the role of Na+/K+ATPase studied in context, that altered electrical activity is coupledwith membrane bound enzyme. Further, we studied the role of antioxidants namely carnitineand lipoic acid on the electrical pattern in young and aged rats. Significant increase in beta wavepattern with a significant decrease in theta pattern (p<0.05) is observed in aged rat brain whencompared to the wave patterns observed in young subjects. However, supplementation of carnitineand lipoic acid to aged rats displayed a normal pattern as that of young rats. Young rats treatedwith carnitine and lipoic acid did not show a significant change. These observations providedan insight that carnitine and lipoic acid have an impact in normalizing electrical activity duringaging. The biological significance of the results is discussed.
