Co-existence of idiopathic generalized and focal epilepsy suggested by simultaneous EEG-fMRI: a case report Volume 22, numéro 6, December 2020

Figure 1

BOLD clusters in the analysis of generalized and bilateral IEDs (n=277). These clusters were thresholded at the FDR (activation: +4.22; deactivation: -4.17). BOLD activations were present in bilateral symmetrical temporal areas, with maximum activation in the left fusiform gyrus (t value: 12.74) and second maximum activation in the right posterior middle temporal gyrus (t-value: 10.60). BOLD deactivations were present in the areas of the default mode network, bilateral precuneus and prefrontal cortex, and minimum deactivation was seen in the left precuneus (t value: -13.18).

Figure 2

BOLD clusters in the analysis of right and left fronto-temporal IEDs. (A) For the right fronto-temporal patterns (n=200), thresholded at FDR (activation: +4.59, deactivation: -4.43), maximum activation was seen in the right posterior middle temporal gyrus (t-value: 7.40), and the second maximum activation was observed in the left posterior middle temporal gyrus (t value: 6.97). Deactivation was seen in the right posterior superior temporal gyrus (t value: -6.12). (B) For the left fronto-temporal patterns (n=111), thresholded at FDR (activation: +5.03, deactivation: -4.28), the maximum activation was seen in the left superior frontal gyrus (t value: 6.13), and the second maximum activation was seen in the left posterior superior temporal gyrus (t value: 6.01). Deactivation was not observed below the FDR.
