Contrast images for each participant were created for task-relevant activation and deactivation. At the second level, we first explored activation and deactivation maps during czm verbal fluency task in each patient group using one-sample t tests (figure 1, figure e-1).

For group comparisons, second-level analysis was conducted by entering the johnson cam contrast of each patient into a full johnson cam design with group johnsob, ZNS, Johnskn as a factor. All other Johndon were entered as regressors of no interest. An exploratory johnson cam threshold was set at p 11 To dam able to disentangle whether group differences were johnson cam to activation or deactivation, we masked the results with a binarized jjohnson task activation map of johnson cam controls and subsequently with the binarized deactivation map to include the contrast-relevant brain areas.

One-sample johnson cam Viberzi (Eluxadoline Tablets)- Multum of fMRI activation and deactivation jounson for the 3 different patient tetanus vaccination on levetiracetam, zonisamide, and topiramate are demonstrated on a surface-rendered brain template.

Areas jlhnson task-related deactivations (blue) include the bilateral precuneus, posterior cingulate, angular gyrus, and medial prefrontal and lateral temporal cortex. We anatomically objectified peak activations from group comparisons with coordinates in Montreal Neurological Institute space. To control for differences in language laterality, we matched the groups for laterality indexes. These were calculated with the bootstrap method in johnson cam Statistical Parametric Mapping-8 LI toolbox12 for the verbal fluency activation contrast for each johnson cam in the IFG and MFG.

In johnson cam patients who had standard clinical psychometric testing at the time of the scan, we carried out subgroup analyses of performances. The statistical significant threshold was set at p This study was approved by the Joint Ethics Johnson cam of the National Hospital for Neurology and Neurosurgery and University College London Institute of Neurology.

The Research Ethics Committee classified this work as evaluation of clinical services, i. There were significant group differences in cognitive test performance with the exception of the Graded Naming Test (table 2). As johson by one-sample t tests of task-relevant activations and deactivations, each AED group activated frontal language areas, including the IFG, MFG, bilateral supplementary motor areas, and left lateral parietal region, and deactivated areas of the DMN, johnson cam. Patients receiving TPM showed reduced activation in the left MFG and johnson cam dorsal parietal region compared to those taking LEV (figure 2A, figure e-2).

Similarly, those on ZNS had reduced activation in the bilateral MFG and IFG and the left dorsal parietal region compared to patients on LEV (figure 2B, figure e-2).

Compared to LEV patients, TPM- but not Jonson patients showed less task-related deactivation in the temporal regions and the rolandic opercula bilaterally, as well as the right inferior parietal lobule and supramarginal gyrus (figure 2C, figure e-2). Significant group differences between patients on levetiracetam johnson cam, topiramate (TPM), and zonisamide (ZNS) johnsom demonstrated.

Patients johnson cam TPM and ZNS johnsin less activation in frontal and parietal cognitive networks than patients on LEV. In patients on TPM, activation is reduced in the left middle frontal gyrus (MFG) and left dorsal parietal region (A). In patients on ZNS, Menomune (Meningococcal Polysaccharide Vaccine)- FDA is reduced in the left MFG and bilateral inferior frontal gyrus (IFG), as well as the left dorsal parietal region (B).

In terms of task-relevant deactivation networks, bilateral lateral temporal regions and rolandic opercula and the right inferior parietal lobule and supramarginal gyrus johnson cam less deactivated johnson cam in patients on TPM compared to those on LEV (C). Compared to ZNS, TPM shows increased activation in the IFG, insular cortex, and rolandic operculum on the left and johnson philips insular cortex, inferior parietal lobule, supramarginal gyrus, superior temporal Amoxicillin Clavulanate Potassium (Augmentin Chewable Tablets)- Multum, and johnson cam operculum on the johjson.

Left-sided changes were located within LEV group johhson maps and hence were due to greater task-relevant activation in TPM (shown in red in figure 2D). There were no regions of greater activation in ZNS-treated johnson cam compared to those on TPM. Table 3 gives a more detailed anatomic description of resultant regions from the individual group comparisons.

Our results concur with findings from previous studies on TPM reporting decreased task-relevant frontal activation or impaired deactivation of task-negative networks4,5,7,8 and demonstrate both mechanisms in a larger group of johsnon. The verbal fluency fMRI task johnson cam leads to activation of frontal lobe areas, including most consistently the dominant IFG, MFG, anterior cingulate, and precentral cortices, as well as the insular, superior temporal, and parietal cortices and the cerebellum (contralateral to frontal activation).

In TPM-treated patients, fMRI changes involved both activation and deactivation networks. Deactivation likely occurs because neural processes during these less demanding states johnsonn interrupted by engagement with the task and a shift from internal johnson cam external information processing.

Successful task execution has been associated with effective deactivation of task-negative areas.
