There were focal signs as picks on the left site trace in a former EEG, and in the last one-slow-wave activity was presented.
A favorable effect of the repetitive transcranial magnetic stimulation (rTMS), is discribed in several publications in the literature. We have applied rTMS in a case of epilepsy with very frequent secondary generalized seizures (in the last 3 months average 3 times a day). The beginning was in the early infant age, and at first the seizures have been partial at right. With the age they became generalized, and sometimes complex seizures have been observed by relatives. The neurological examination proved only a latent right-sided hemiparesis. There were focal signs as picks on the left site trace in a former EEG, and in the last one-slow-wave activity was presented. CT did not shure findings. T2 and FLAIR positions of the MRT reveated medial temporal sclerosis bilaterally, more pronounced at right. In IR local bilateral temporal atrophy was demonstrated, more pronounced at the left side. The medication during the last two years consisted of Tegretol 3x200 mg/d and Antelepsin 2x 0.5 mg/d. In the past other AEM have been tried, even in double combination.

Simultaneously the bioelectrical brain activity was registered using 8-chanel Holter-electroencephalography (EEG).
The study was performed in 15 pilots, tested by the method of SACM with maximal +Gz-8G load. The cardiac reactivity was assessed using 3chanels electrocardiography (ECG). A parallel infra-red pletismography at the level of the right temporal artery was applied and the delayed pulse wave (measured in milliseconds between R wave of the ECG and the peak of the pletismography) was estimated. By means of transcranial Doppler sonography the BFV of the right MCA at a depth of 50–55 mm was monitored.

The subsequent increase in the acceleration in the range of 4,5 – 5G resulted in a common delay of the EEG activity with shifting to 6-8 Hz teta frequency maximums.
In overloading up to 3G an increase in the quantity of the fast wave activity within the range of 12–14 Hz was observed. The subsequent increase in the acceleration in the range of 4,5 – 5G resulted in a common delay of the EEG activity with shifting to 6-8 Hz teta frequency maximums. In some of the pilots an appearance of delta activity (2-4 Hz) was found during the 7-8 G hypergravitational stress. A decrease in the MCA BFV was preceded by the appearance of a “blackout” period. The usage of an antigravity suit and antigravity straining maneuvers prevented the severe reduction of brain circulation.

The maximums in the EEG delta range can predict the appearance of “blackout” periods and the subsequent loss of consciousness (e.g. G-LOG).
The study shows typical gradual changes of electrophysiological brain activity and cerebral hemodynamics, which can be used as objective criteria for adaptation to the hypergravitational stress. The maximums in the EEG delta range can predict the appearance of “blackout” periods and the subsequent loss of consciousness (e.g. G-LOG).

In the other report [17], a clinically brain-dead patient with cerebral circulatory arrest on TCD and angiography, EEG examination became isoelectric only several hours later.
a reliable test that can extend clinical criteria in the assessment of the diagnosis brain death. Sensitivity and specificity for a positive pattern of oscillating flow and systolic spikes, indicating cerebral circulatory arrest were high in selected patient population. Few false-positive cases were reported in the literature, but only two instances [10, 17] were defined as false positive according to predefined criteria in this meta-analysis. In one patient [10] with TCD criteria of cerebral circulatory arrest, weak respiration was recorded after TCD examination. In the other report [17], a clinically brain-dead patient with cerebral circulatory arrest on TCD and angiography, EEG examination became isoelectric only several hours later. Both these patients became brain dead shortly after the false-positive TCD examination. Large opening of the scull may result in false negative results. After evaluating validity of TCD diagnosed brain death depending on the time lapse between clinical diagnosis and the performance of TCD, a specificity of 100% 24 hours after the clinical diagnosis was obtained [13].

A randomized, controlled clinical trial with simulated rTMS found a statistically significant reduction in EEG epileptiform activity and improvement in some aspects of cognitive activity lasting about 2 months after stimulation.
Low frequency rTMS (≤ 1 Hz) decreases cortical excitability, while higher frequencies (> 5 Hz) increase it. In experimental conditions, low frequency rTMS (0.5 Hz) reduces the incidence of epileptic status and prolongs the latency of pentilentetrazol-induced seizures in rats. The results from the application of low frequency rTMS in clinical conditions range from optimistic (reduction in seizure frequency by 36.2%) in uncontrolled studies to moderate and not very reliable in controlled randomized trials [2, 27]. In a controlled blind study on 24 patients with focal epilepsy (temporal and extratemporal) and a coil located on the epileptogenic focus, a statistically significant change in relapse frequency was not found. A better effect was observed in neocortical than in mesiotemporal focuses [50]. A randomized, controlled clinical trial with simulated rTMS found a statistically significant reduction in EEG epileptiform activity and improvement in some aspects of cognitive activity lasting about 2 months after stimulation. All patients had cortical defects on brain convexity [27]. The response of surface and neocortical temporal foci correlates with the modern capabilities of TMS – the intensity of the induced electric field decreases rapidly in depth. The introduction of a new design of the stimulating coil, called H-coil would improve the stimulation of deep epileptogenic foci (distance of 5 cm from the scalp). It was found that rTMS is well tolerated by patients and side effects are mild (17.1%). The most frequent complication is headache.

Addressing some key methodological issues (the most appropriate area to promote, optimal simulation parameters), combined with modern technological innovations (H-coil, combining rTMS with EEG) would improve the applicability of the methodology in the future [27].
The introduction of a new design of the stimulating coil, called H-coil would improve the stimulation of deep epileptogenic foci (distance of 5 cm from the scalp). It was found that rTMS is well tolerated by patients and side effects are mild (17.1%). The most frequent complication is headache. Repetitive TMS poses little risk of inducing seizures in strict compliance with approved work instructions [5]. Despite expectations for a new modulation treatment of epilepsy with TMS, the results from its application are poor. Addressing some key methodological issues (the most appropriate area to promote, optimal simulation parameters), combined with modern technological innovations (H-coil, combining rTMS with EEG) would improve the applicability of the methodology in the future [27].

Promising prospects for solving this problem is the simultaneous application of TMS and EEG, offering high resolution in time and evaluation of cortical reactivity and connections [45].
Recently, in scientific practice combined functional MRI (fMRT) and neuronavigated TMS were introduced. This allowed precise localization of areas subject to stimulation and evaluation of TMS-induced anatomical and functional effects on the brain. TMS-induced metabolic changes can be measured using PET and changes in blood oxygen saturation – with fMRT. Both methods have short-term effectiveness: seconds for fMRT and up to five minutes for PET, so that brain responses in the first 10 ms after the stimulus are ignored. Promising prospects for solving this problem is the simultaneous application of TMS and EEG, offering high resolution in time and evaluation of cortical reactivity and connections [45]. Induced by TMS EEG responses are with specific latency and high spatial and temporal resolution. This allows evaluation of impulse spreading through intra-and interhemispheric corticocortical fibers. The introduction of new simulation techniques and equipment, and the identification of optimal simulation parameters would lead to more pronounced and long lasting therapeutic effects.

Six hours Real-time TCD-EEG (Delica NSD-8100) is performed in pre-surgical patients with refractory epilepsy and pre-surgical patients with Moyamoya disease and transient ischemic attacks.
This is an on-going single-center observational study. Six hours Real-time TCD-EEG (Delica NSD-8100) is performed in pre-surgical patients with refractory epilepsy and pre-surgical patients with Moyamoya disease and transient ischemic attacks. The TCD-EEG monitoring includes 10-20 system 16 channels EEG and bilateral middle cerebral artery blood flow velocity (CBFV) monitoring. To further investigate TCD value in the localization of epileptogenic focus, SPECT is performed, if available, in patients with seizure attacks for comparative analysis. To induce transient ischemic attacks, 3 minutes hyperventilation is performed in patients with Moyamoya disease. In patients with seizure attacks, we observe: 1) the synchronicity between CBFV changes and epileptic discharges;2) the consistency between CBFV changes and SPECT findings; 3) the relationship between CBFV changes and epileptogenic focus as defined by EEG and SPECT;4) the correlation between TCD-EEG findings and prognosis after operation. In patients with Moaymoya disease, we observe: 1)the EEG and CBFV changes during hyperventilation; 2) the synchronicity between clinical symptoms and TCD-EEG findings;3) the correlation between TCD-EEG findings and prognosis after operation.

The EEG repetitive visual stimulation and visual evoked potentials were associated with color hallucinations during and after the investigation (Charles Bonnet syndrome).
The right eye was with pars plana vitrectomy and corneal leucoma and the left bulb was with phthisis. Ocular fundus was not visible on both sides. The 2D/3D/4D eye images showed severe deformation of the left eye with chronic retinal detachment and optic nerve atrophy. The right bulb was fully anechoic, with a normal shape but no images of the lens, optic disc and optic nerve were obtained due to silicon filling of the vitreous. Both ophthalmic arteries and veins had normal ultrasound pattern. The EEG repetitive visual stimulation and visual evoked potentials were associated with color hallucinations during and after the investigation (Charles Bonnet syndrome). These findings correlated with neuroimaging studies where normal occipital cortex, optic nerve atrophy and severe eye deformation were found.

The parallel application of EEG and visual evoked potentials gives additional information about the functional capacity of the retina, visual pathways and the occipital cortex after the trauma.
The parallel application of EEG and visual evoked potentials gives additional information about the functional capacity of the retina, visual pathways and the occipital cortex after the trauma. Dispite of the practical blindness established from the neuro-ophthalmological examination, during the repetitive photostimulation a change in the baseline alpha activity was registered on the occipital cortex, which is significant only in the left temporooccipital area during stimulation of the right eye. This electrophisiological sign for photic influence on the visual cortex allows us to assume the existence of some functional capacity reserve of the right eye and visual pathways, which matters for the prognosis of the illness.

The diagnosis of sporadic Creutzfeldt-Jakob disease (CJD) is still made on clinical grounds, with rapidly progressive dementia and electroencephalogram (EEG) changes as hallmarks, while definite confirmation requires neuropathological evaluation.
The diagnosis of sporadic Creutzfeldt-Jakob disease (CJD) is still made on clinical grounds, with rapidly progressive dementia and electroencephalogram (EEG) changes as hallmarks, while definite confirmation requires neuropathological evaluation. Several publications demonstrated that signal increase in the cerebral cortex, caudate nucleus and putamen on diffusionweighted imaging (DWI) and fluid attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) is useful in diagnosis of sporadic CJD. Transcranial B-mode sonography (TCS) enables visualization of different tissue echogenicity, which can be associated with changes in cerebral metabolism of various metals, one of potential mechanisms of brain damage in CJD.

There are conclusions from routine electroencephalograms (EEG) most of which are normal (last EEG from 1999).
A 23-year-old male with dysgenesis of the corpus callosum is examined. The male is adopted, therefore there are no records of his prenatal development. There is history of a single febrile seizure at 8-months of age, followed by antiepileptic medical treatment with phenobarbital and tegretol since 2-years of age until year 2000. During that period no imaging studies were made. There are conclusions from routine electroencephalograms (EEG) most of which are normal (last EEG from 1999). According to the father, the patient has poor vocabulary background, cannot execute coordinated activities with both hands, has a periodic migraine accompanied by copious amounts of perspiration and irritability of noise, followed by falling asleep; suffers from various phobias. Sometimes he experiences quivering of the limbs and problem swallowing solid foods. He finished high school with low grades after a lot of extra work. He has made short attempts to work and was unsuccessful in trying to fit in the social environment.

At the Port-Royal Hospital in Paris, under the supervision of professor A. Minkovski, doctor L. Daskalova–Curzi studied EEG for premature, mature neonates as well as neonates at risk. Her research helps assess the impact of hemodynamic changes associated with rhythm and respiratory failure in newborns, on the bioelectric activity of the brain. With her research she proves the importance of the polysomnographic methodology as an objective method for classifying respiratory disorders during sleep as wells as differentiation of central and obstructive apnea. Nowadays, polysomnography is a routine method in the intensive treatment of children with

In electrophysiological methods (EEG, MEG) the indicator giving information about the mirror function of the neurons, is the so-called μ (mu) rhythm.
In electrophysiological methods (EEG, MEG) the indicator giving information about the mirror function of the neurons, is the so-called μ (mu) rhythm. The μ-wave reflects the electrical activity of the motor cortex at rest. It represents a synchronized activity of multiple pyramidal neurons with a frequency ranging from 8 to 13 Hz. Normally these waves are suppressed by body movements, phenomenon called “event-related desynchronization”. Already in 1950, Gastaut discovered that such desynchronization also occurred during observation and/or imagining a motor act, which later became associated with the presence of a network of mirror neurons. Similar results were also reported using MEG [31].
