Analysis of Brain Activity for Given Auditory Stimulus Using Functional MRI

H. N. Suma and H. N. Champa
Abstract—Functional Magnetic Resonance Imaging (fMRI) is one of the most recent (and most advanced) techniques to record brain activity. fMRI Technique can be used to produce activation maps showing which parts of the brain are involved in a particular physical / mental process. It measures brain function indirectly, i.e., not through the direct computation or calculation of neuronal activity, but through a mapping of blood perfusion levels in the brain. This method uses perfusion as a substitute or proxy for brain activity. This is because of the demonstrated fact that neuronal activation in any region of the brain increases the flow of blood to that region. A trial to understand and study the brain activity patterns for a given auditory stimulus. The auditory cortex of the brain is expected to show activity on either hemisphere in a healthy subject. A study done over different age groups or patients with abnormalities is useful to identify reasons of reduced or abnormal (diseased) activities of human body.

Index Terms—Auditory cortex, auditory stimulus, blood oxygenation, brain activity, functional magnetic resonance imaging.
