Computational Analysis Techniques: A Case Study On Fmri For Autism Spectrum Disorder

Functional magnetic resonance imaging (MRI) is one of the most promising techniques in neuro-imaging. It is mainly used to either record the response of a subject to a certain task (task based fMRI) or to assess the functional connectivity while at rest (resting state fMRI). In this survey, both fMRI techniques are explained and the most commonly used techniques in each of them are discussed and criticized. For each technique the hypothesis used and the mathematical background is discussed
