- fig 1.
Diagram illustrating the acquisition of MR data triggered to the presence (ON state) or absence (OFF state) of an EEG discharge.
- fig 2.
Composite image showing BOLD activation superimposed over T1-weighted anatomic image (reconstructed from 3D MPRAGE acquisition), which corresponds to EEG activity. The region of activation covers a 4.8-cm2 area of the left lateral temporal lobe. This region is distinguished by high positive z scores, with a positive z score maximum of 6.2 and a mean of 2.6 ± 1.1 (standard error, 0.1).

Composite images showing BOLD activation superimposed over T1-weighted anatomic image (reconstructed from 3D MPRAGE acquisition), which corresponds to EEG activity.
A, Right posterior temporal lobe BOLD activation is shown. The region of activation covers a 4.4-cm2 area, with a positive z score maximum of 2.9 and a mean of 1.2 ± 0.6 (standard error, 0.06).
B, Additional focus of right parietal BOLD activation is seen, which is in contiguity with the posterior temporal lobe activation above. Within this 3.2-cm2 region of activation, the positive z score maximum was 3.6, with a mean of 1.6 ± 0.8 (standard error, 0.1).
