Correlation based active regions identification from fMRI data

The studies of neuroimaging have been shown that odorant-induced responses to the prolonged stimulation in primary olfactory cortex (POC) are characterized by a rapidly habituating time course. This paper is concerned the identification of the active regions in the brain after that stimulation. The correlation technique is used to obtain the quantity that could be a parameter to exhibit the regions of interest. This paper also illustrates the ways to remedy problems that occurred during data acquisition process. The real functional magnetic resonance imaging (fMRI) data obtained from the experiment is used to evaluate the performance of the method.
