Human Brain Mapping with Functional Magnetic Resonance Imaging

Abstract -

Functional Magnetic Resonance Imaging (fMRI) is a relatively new technique that allows imaging of the brain while it is performing a task. Traditional MRI images take many minutes to collect but in the last 5 years or so, ultra fast imaging methods have been developed that provide temporal resolution down to about 1 second and spatial resolution down to about 1-2 millimeters. The possibility for the first time of such high resolution noninvasive whole human-brain imaging has caused tremendous excitement in the Neuroscience community. However the problem of analysing fMRI data is a complex one involving elements of time series, image processing and inverse problems. In this talk we will give some background to the problem and describe some of our approaches to the signal processing issues. We illustrate with results from a particular set of experimental data.
