A review of EEG and fMRI studies JF Neurosciences Journal JO Neurosciences (Riyadh) FD Prince Sultan Military Medical City SP 330 OP 344 VO 18 IS 4 A1 Hafeezullah Amin A1 Aamir S. Malik YR 2013 UL http://nsj.org.sa/content/18/4/330.abstract AB Human memory is an important concept in cognitive psychology and neuroscience. Our brain is actively engaged in functions of learning and memorization. Generally, human memory has been classified into 2 groups: short-term/working memory, and long-term memory. Using different memory paradigms and brain mapping techniques, psychologists and neuroscientists have identified 3 memory processes: encoding, retention, and recall. These processes have been studied using EEG and functional MRI (fMRI) in cognitive and neuroscience research. This study reviews previous research reported for human memory processes, particularly brain behavior in memory retention and recall processes with the use of EEG and fMRI. We discuss issues and challenges related to memory research with EEG and fMRI techniques.
