Individual performance in mental image processing is correlated with dynamic changes in the gamma-band brain activity

Individual Differences in Mental Imagery Tasks: A Study of Visual Thinkers and Verbal Thinkers

“…Particularly for v1, β bands with central frequencies of 20 and 25 Hz (y axis) show a more highly activated band (reddish) in the direction of the x-axis (time). This corresponds to our previous observation of the presence of low-γ band activity (around 30 Hz) during image processing [20] . On the other hand, compared to sensors in the visual area, those in the frontal language areas show an overall bluish tint, with Group L showing markedly higher activation, particularly under verbal conditions.…”

Brain activities of visual thinkers and verbal thinkers: A MEG study

“…Some EEG/MEG studies [3,12,13,20] suggest that the beta-band power can be used to evaluate the degree of individual performances regarding visual and verbal processing. Therefore, we focus on the brain activities of the high beta-band frequencies (25 Hz), among the alpha (10 Hz), beta (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25), and low gamma bands (30-50 Hz) see Fig.…”

“…Therefore, we focus on the brain activities of the high beta-band frequencies (25 Hz), among the alpha (10 Hz), beta (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25), and low gamma bands (30-50 Hz) see Fig. 3(a).…”

“…Also there are a few papers, which discuss "visual" or "verbal" thinking patterns [15][16][17][18]. Iwaki et al [19,20] have investigated the relationship between image processing ability and brain activation patterns by examining the distribution of visual event-related neural activities in evoked mental image processing. Here, we analyzed differences in image processing associated with spontaneous mental activity.…”

“…Subjects were separated into two groups based on the results of the 5-item questionnaire survey used to evaluate their ability to form mental images, as in our earlier works [2,20,21]. Blazhenkova et al [18] also develop a questionnaire to evaluate subjects according to visual/verbal factors.…”
