Decoding of visual information from human brain activity_A review of fMRI and EEG studies

Brain is the command center for the body and contains a lot of information which can be extracted by using different non-invasive
techniques. Electroencephalography (EEG), Magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI)
are the most common neuroimaging techniques to elicit brain behavior. By using these techniques different activity patterns can
be measured within the brain to decode the content of mental processes especially the visual and auditory content. This paper
discusses the models and imaging techniques used in visual decoding to investigate the different conditions of brain along with
recent advancements in brain decoding. This paper concludes that it's not possible to extract all the information from the brain,
however careful experimentation, interpretation and powerful statistical tools can be used with the neuroimaging techniques for
better results.
