The localizing and lateralizing values of eye and head ictal deviations during frontal lobe seizures are still matters of debate. In particular, no specific data regarding the origin of ipsilateral head turning in frontal lobe seizures are available. We report a patient with frontal lobe seizures associated with reproducible, early, ipsilateral head deviation, where imaging and video-stereo-ele...

Objective The aim of the present work was to observe the activation/deactivation of cerebral functional regions after electroacupuncture (EA) at Yintang (EX-HN3) and GV20 by functional MRI (fMRI). Design A total of 12 healthy volunteers were stimulated by EA at Yintang and GV20 for 30 min. Resting-state fMRI scans were performed before EA, and at 5 and 15 min after needle removal. Statistical p...

in the recent years, the coherence index is used in many electroencephalographic studies for investigation of brain connectivity in children with adhd disorder. it is suggested that the coherence is a useful index in discrimination of adhd subjects from normal subjects. however, a few studies are accomplished in subtypes of adhd to identify of differences in functional connectivity between adhd...

The frontal lobe is the largest lobe of the brain and it is thus commonly involved in stroke. Moreover, almost one in five strokes is limited to the prerolandic areas.This high frequency of anatomical involvement is in sharp contrast with the apparent rarity of clinical frontal dysfunction in stroke. It is remarkable that frontal behavioural syndromes have rather uncommonly been reported in pat...

Frontal lobe epilepsy accounts for only 10-20% of the patients in surgical series, but the incidence in non-surgical patient cohorts seems to be much higher. The typical clinical presentation of the seizures includes contralateral clonic movements, uni- or bilateral tonic motor activity as well as complex automatism. The yield of surface EEG may be limited due to the difficulty in detection of ...

Frontal lobe epilepsy makes up between 20 and 30% of all partial epilepsies and is the biggest subgroup of the extratemporal lobe epilepsies. Of the patients who undergo surgery for epilepsy up to 18% have a frontal lobe focus. The aetiology of frontal lobe epilepsy is varied, clinical semiology is diverse and seizures are often frequent, disabling and refractory to treatment. Imaging and EEG f...

Patients with limited focal frontal and nonfrontal lesions were tested for visual perspective taking and detecting deception. Frontal lobe lesions impaired the ability to infer mental states in others, with dissociation of performance within the frontal lobes. Lesions throughout the frontal lobe, with some suggestion of a more important role for the right frontal lobe, were associated with impa...

AIM Comprising large areas of association cortex, the parietal lobe is part of an extensive synaptic network elaborately intertwined with other brain regions. We hypothesize that such widespread projections are responsible for producing inaccurate localisation readings on scalp EEG and clinical semiology in patients with parietal lobe epilepsies, as opposed to frontal or temporal lobe epilepsie...

Temporal lobe epilepsy (TLE) is typically associated with long-term memory dysfunction. The frontal lobes support high-level cognition comprising executive skills and working memory that is vital for daily life functioning. Deficits in these functions have been increasingly reported in TLE. Evidence from both the neuropsychological and neuroimaging literature suggests both executive function an...
