Abstract Visual imagery is a dynamic process recruiting network of brain regions. We used electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) fusion to investigate the dynamics category selective in medial parietal cortex (MPC), ventral temporal (VTC), primary visual (V1). Subjects attended separate EEG fMRI sessions where they created mental images personally familiar people place stimuli. The contrast comparing replicated previous findings category-selectivity cortex. In addition, greater activity for places was found lateral memory areas, frontal eye fields, inferior sulcus, intraparietal sulcus. contrast, fusiform face area right posterior superior Using multivariate decoding analysis fMRI, we could decode individual stimuli within preferred VTC. A more complex pattern emerged MPC, which represented information that not restricted category. were also able data. EEG–fMRI indicated similar timings MPC VTC during imagery. However, VTC, higher regions an early time window, later window. correlations V1 occurred period, possibly reflecting top-down progression from category-selective
