“…Wang et al (54) reported that the Rolandic operculum is associated with the neural mechanisms of tic generation. Decades ago, it was discovered that critical electrical discharges in temporal lobe epilepsy always affect extratemporal structures, such as the Rolandic operculum (55). In the present study, lower NH was found in the bilateral Rolandic operculum of patients with rTLE and in the right Rolandic operculum of patients with lTLE.…”

BackgroundAbnormalities of functional connectivity in the somatomotor network have been thought to play an essential role in the pathophysiology of epilepsy. However, there has been no network homogeneity (NH) study about the ventral somatomotor network (VSN) in patients with temporal lobe epilepsy (TLE). Therefore, we explored the NH of the VSN in TLE patients in this study.MethodsThe sample included 52 patients with left temporal lobe epilepsy, 83 patients with right temporal lobe epilepsy, and 68 healthy controls. The NH method was utilized to analyze the resting-state functional magnetic resonance imaging data.ResultsCompared to the controls, rTLE patients had significantly higher NH in the bilateral postcentral gyrus, and significantly lower NH in the bilateral Rolandic operculum and the right superior temporal gyrus (STG). The NH values of the left postcentral gyrus were significantly higher in lTLE patients than in the healthy controls, and lTLE patients had lower NH in the right Rolandic operculum. The altered NH in the postcentral gyrus was negatively correlated with the illness duration, and the decreased NH in the left Rolandic operculum was negatively correlated with the executive control reaction time (ECRT).ConclusionOur findings suggest that altered NH of the postcentral gyrus, Rolandic operculum and STG might be associated with the pathophysiology of TLE, and thus, highlight the contribution of the VSN to the pathophysiology of TLE.

“…Additionally, ictal propagation to the cingulate gyrus is frequently observed among patients with temporal lobe epilepsy. 38 Therefore, it is no surprise that all of the posterior cases had features suggestive of temporal lobe origin. In our series, ictal patterns involved the ipsilateral temporal lobe; bilateral temporal ictal patterns have also been described.…”

“…During the clinical course of a typical temporal lobe seizure, an asymmetrical dystonic posture may affect the upper limb, contralaterally to the epileptic focus [12, 13]. This has been attributed to the spread of the discharge to the ipsilateral basal ganglia, mainly the sensorimotor part of the putamen, as supported by ictal single photon emission computed tomography (SPECT) data, showing ipsilateral hyperperfusion involving the lenticular nucleus [14] (see also Semah in this issue).…”

This article attempts an overview of the clinical and electrophysiological evidence supporting the involvement of the basal ganglia in epileptic seizures. In contrast to animal data, evidence for a role of these structures in human epilepsies is lacking. However, from the theoretical point of view, it remains conceivable that, given their strong interconnectivity, basal ganglia could be functionally linked to the cerebral cortex during an epileptic seizure. Several clinical ictal aspects have been suggested to be compatible with the involvement of basal ganglia, namely, ictal dystonic posturing during temporal lobe seizures, rotatory seizures and paroxysmal dyskinesia‐like seizures. On the other hand, basal ganglia dysfunction may also influence some aspects of epilepsy, as suggested by pure basal ganglia pathology such as Parkinson's disease, or the described effect of an acute basal ganglia lesion in epileptic patients. The data discussed in this review may stimulate further research to link basic scientific data to human epilepsies, and lead to the development of novel therapeutical solutions.
