Identification of Epileptic Seizure Using ReHo from Rs-fMRI

Abstract

Localization of the epileptic seizure sources is a very essential procedure that assists the surgeon in concentrating on the diseased area leaving its vicinity unaffected. Epilepsy is a condition in which the brains own neurons releases abnormal electrical pulses that inhibits the normal activities of other neurons, that needs surgery to be corrected. Hence to enhance the surgical intervention a suitable methodology must be formulated that ensures the spatial localization of the epileptic seizure. This paper studies about Regional homogeneity (ReHo) which is a powerful correlating method that could be employed in measuring the brain activity. Two sample t tests are followed to compare the pre-defined standard with the ReHo that provides clear detailed epileptic seizure localization. Amplitude of Low Frequency Fluctuations (ALFF) is also measured and the resultant is subjected to sample t test and they are compared with ReHo to measure the similarity.
