A summary of the task EEG-fMRI studies since 2014.

Reference	Application Field	Subjects	MR field	MR sequence details	EEG	preprocessing	TASK	Results
Herweg et al. (52)	Behavioral/ Cognitive	19 Healthy Control	3T	EPI TR/TE = 4,000/25 ms RES: 2 × 2 × 2 mm	Braincap MR; Brain Products 64-channels	MRI: SPM12b EEG: BrainVision Analyzer 2.0; EEGLAB	Recognition memory task inside of the scanner.	Theta-alpha power is linked to hippocampal connectivity with the striatum and PFC
Zotev et al. (53)	Neurofeedback	15 Healthy Control	3T	EPI TR/TE = 5.0/1.9 ms RES: 0.94 × 0.94 × 1.2 mm 3 mm	Brain Products 32-channels	EEG: BrainVision Analyzer 2.1 software Frmi: AFNI	Retrival of happy autobiographical monets	Emotional control training can improve alpha activity and functional connectivity of amygdala and prefrontal cortex
Pisauro et al. (54)	Neuroscience	21 Healthy Control	3T	EPI TR/TE = 2.5 s/40 ms RES: 3 × 3 mm	Brain Amps MR-Plus 64-channels	EEG: Matlab MRI: FMRIB's Software Library	Independent reward-based decision-making task	task-dependent correlation with the ventromedial prefrontal cortex and the striatum
Andreou et al. (55)	Translational Psychiatry	22 Healthy Control	3T	EPI TR/TE = 2,000/ TE = 25 ms RES: 1 × 1 × 1 mm	BrainVision Recorder 64channel	EEG: Brain Vision Analyzer Version 2.0 MRI: SPM 12	Gambling Task	Negative feedback: Increase in theta band power associated that correspond with activation of fronto-parietal areas. Positive feedback: Increasing in beta band power that reflect activation of subcortical areas
Guo et al. (56)	Neuropsychology	20 Healthy Control	3T	EPI TR/TE = 2,000 ms/35 ms RES: 1 × 1 × 1 mm	Net Station (EEG Electrical Geodesics) 64-channels	EEG: Net Station Software MRI: SPM8	Monerary gambling task	Egg-fMRI acquisition during gambling task underline activation of a posterior cingulate, medial pre-frontal cortex and ventral striatum
Zotev et al. (53)	Neurofeedback	30 Patients with PTSD	3T	EPI TR/TE = 2,000/30 ms RES: 1.875 × 1.875 × 2.9 mm	Brain Products 32 Channels	EEG: BrainVision Analyzer 2.1 software Frmi: AFNI	Think of and write down five happy autobiographical memories.	rtfMRI-nf of the amygdala activity has the potential to correct the amygdala-prefrontal functional connectivity deficiencies specific to PTSD
Zich et al. (57)	Neuropsychology	24 Healthy Control	3T	EPI TR/TE = 1.5 s/2.52 ms RES: 3.1 × 3.1 × 3.0 mm	Brain Product 32-channels	EEG: Brain Vision Analyzer RMI: spm8	Eeg neurofeedback- motor task	Indicate a complex relationship between MI EEG signals and sensorimotor cortical activity and support the role of MI EEG feedback in motor rehabilitation.
