BACKGROUND AND PURPOSE Voxel-mirrored intrinsic functional connectivity allows the depiction of interhemispheric homotopic connections in the human brain, whereas time-shift intrinsic functional connectivity allows the detection of the extent of brain injury by measuring hemodynamic properties. We combined time-shift voxel-mirrored homotopic connectivity analyses to investigate the alterations ...

Objectives: Depression and anxiety are commonly seen among epileptic patients. These comorbidities have a negative effect on achievement of effective treatment and improvement in the quality of life of epileptic patients. We aimed to determine the frequency of anxiety and depression in epilepsy and in subgroups of epileptic patients and their correlation with disease duration and seizure freque...

Glial cells are now recognized as active communication partners in the central nervous system, and this new perspective has rekindled the question of their role in pathology. In the present study we analysed functional properties of astrocytes in hippocampal specimens from patients with mesial temporal lobe epilepsy without (n = 44) and with sclerosis (n = 75) combining patch clamp recording, K...

PURPOSE To evaluate speech recognition in patients with focal intractable epilepsy and surgical resections in the nondominant (right) hemisphere. METHODS Speech recognition was tested prospectively, under different listening conditions, in 22 patients with right temporal lobe (11 patients) or extra-temporal lobe epilepsy. All were left-hemisphere dominant for language on preoperative intracar...

Anterior temporal lobe resection controls seizures in 50-60% of patients with intractable temporal lobe epilepsy but may impair memory function, typically verbal memory following left, and visual memory following right anterior temporal lobe resection. Functional reorganization can occur within the ipsilateral and contralateral hemispheres. We investigated the reorganization of memory function ...

Functional magnetic resonance imaging has demonstrated reorganisation of memory encoding networks within the temporal lobe in temporal lobe epilepsy, but little is known of the extra-temporal networks in these patients. We investigated the temporal and extra-temporal reorganisation of memory encoding networks in refractory temporal lobe epilepsy and the neural correlates of successful subsequent

Objective: To examine the expressions of mitochondrial translation elongation factors Tu (EF-Tumt) and Ts (EF-Tsmt) in the epileptogenic zone of patients with refractory temporal lobe epilepsy. Methods: Epileptogenic zone resection specimens were obtained from 20 patients with refractory temporal lobe epilepsy. Control samples were temporal lobe cortex tissues derived from 6 non-epileptic patie...

Children with temporal lobe epilepsy frequently suffer memory deficits, often marked in face processing. To determine the neural correlates of this dysfunction, we investigated face processing in adolescents with intractable epilepsy compared to typically developing controls. The M170 and M220 MEG event-related fields (ERFs) were recorded while the adolescents completed an n-back task on blocks...

Anterior temporal lobe resection controls seizures in 50–60% of patients with intractable temporal lobe epilepsy but may impair memory function, typically verbal memory following left, and visual memory following right anterior temporal lobe resection. Functional reorganization can occur within the ipsilateral and contralateral hemispheres. We investigated the reorganization of memory function ...

most common hypotheses of seizure initiation are increased neural excitation, decreased inhibition or both. but, the conditions that lead to these activation states not to be clear yet. recent studies challenge traditional concepts and indicate new evidence that a key epileptogenic process may actually begin in the blood vessel. seizures could be initiate by a variety of insults to the brain, s...
