Analysis of functional connectivity can be useful tool which can describe the correlation between functionally related regions. This study was performed with seven volunteers on a 3T scanner. Time courses from auditory cortex were used as references in correlation analysis in individual subject. Similarity of the time courses demonstrated the connection between structures in auditory pathway and gives the reason to applied correlation analysis. Results demonstrate a tight functional relation between auditory cortex and brainstem in the human brain and provide an improvement in the t-test analysis about location of activated areas within the brainstem by correlation analysis
