Laura Bonanni, ( University of Chieti-Pescara “G. D’Annunzio”, Italy )

Background: 1) Temporal lobe Epilepsy and Alzheimer’s disease (AD) show similarities of high clinical interest. In AD patients, the incidence of convulsive seizures is 10 times higher than healthy controls and 87 times more frequent with “early-onset” disease manifestation; 2) cognitive decline starts 5.5 years earlier in AD patients with epilepsy than AD controls; and 3) hippocampus hyperactivity is a risk factor for mild cognitive impairment (MCI) and rationalized an antiepileptic preventive treatment trial in MCI using Levetiracetam (NCT01044758). Aims: show new evidence about the prevalence of EEG signatures of over-excitation of cerebral cortex and abnormal functional connectivity networks in AD and Lewy body diseases.

In this symposium we review the available data for invasive and non-invasive markers for DBS efficacy, and present our own results based on invasive recordings from the human ANT.

Symposium 4
Evoked potentials and their clinical implications in CNS diseases
Organiser-Chair: Anna Pokryszko-Dragan

Evoked potentials as a monitoring tool in CNS diseases.
Beata Zakrzewska-Pniewska and Monika Nojszewska
P300 potential in the assessment of cognitive performance in CNS diseases.
Anna Pokryszko-Dragan

The first presentation concerns evoked potentials (EP) as a monitoring tool in CNS diseases. EP reveal normal or altered conduction in selected tracts of the central nervous system in a quantifiable way. Since alteration of signal conduction is the main mechanism of symptoms and signs in many CNS disorders, especially in multiple sclerosis (MS), multimodal EP may serve as a representative measure of the functional impairment in such diseases. Moreover, EP have been shown to be predictive for diseases course, and thus might help to select patient groups at high risk of progression for clinical trials. EP can detect deterioration, as well as improvement of impulse propagation, independently from the mechanism causing the change. Therefore, they might be candidates for biomarkers in many CNS disorders. In the second presentation the role of event-related potentials  will be  highlighted in the assessment of cognitive performance, with a special regard to P300 component. The examples will be shown of  P300 evaluation , complementary to neuropsychological tests, in the patients with primary CNS disorders as well as with CNS involvement in the course of systemic diseases. The pros and cons of the method and its potential future applications will be discussed.

Symposium 5
The Construction of Pain
Organiser-Chair: Luis Garcia-Larrea

The Symposium will discuss how the aversive experience we call “pain” emerges from the coordinated activation of multiple brain areas.

Luis Garcia-Larrea will describe the so-called “pain matrix” as a fluid system of several interacting networks. Initial processing in a ‘nociceptive matrix’ receiving ascending input leads to activation of second-order structures supporting ‘salience’  attributes , passage  from  pre-conscious  nociception  to  conscious  pain, and encoding in memory systems.
Hélène Bastuji will discuss data from intracortical EEG, illustrating  that nociceptive processing is initiated in parallel in sensory and limbic areas, to converge in the anterior insula in less than one second, and underscoring the role of this region in integrating limbic with sensory input to initiate a perceptual decision on the stimulus ‘painfulness’.
Markus Ploner will discuss approaches to cortical nociceptive processing via the study of brain oscillations. Conscious pain depends on integration of brain activity across different areas, and functional connectivity between sensory and high-level networks should determinant for access to consciousness. Interactions between neural oscillations, together with the implementation of graph theory methods are likely solutions to gain access to local and global levels of processing, thus allowing the study of normal and abnormal pain with non-invasive measures.

Symposium 6
Diagnosing amyotrophic lateral sclerosis
Organiser-Chair: Birger Johnsen

Diagnostic criteria in ALS, a review.
Birger Johnsen
Application of diagnostic criteria in individual cases: practical problems.
Mamede De Carvalho
New techniques to support the diagnosis of ALS.
Hatice Tankisi

The diagnosis of amyotrophic lateral sclerosis (ALS) is clinical and relies on the presence of progressing disease with both upper motor neuron (UMN) and lower motor neuron (LMN) involvement, and the exclusion of other diseases. The “revised El Escorial criteria” (rEEC) has proposed an electrophysiological algorithm for supporting diagnosis, which was refined in the recent “Awaji criteria” (AC) with the intention of facilitate earlier diagnosis. The criteria have a high specificity, lack sensitivity although most studies show a higher sensitivity of the AC than the rEEC, and have a rather large inter-rater variation when used by untrained physicians indicating that their use may require training. Development of a reliable objective method for detection of UMN involvement is the most critical item for improvement of diagnostic sensitivity. This symposium will review current criteria, encompass their potentialities and limitations including their correct application and incorporation with clinical findings, and finally review promising new techniques for diagnosing and monitoring of ALS as transcranial magnetic stimulation, the novel motor unit number estimation (MUNE) method, MScanFit MUNE, ultrasound and neuroimaging. The session will be interactive with the presentation of a number of clinical vignettes regarding diagnostic categorization, underlying difficulties, and strategies to overcome practical problems.

Symposium 9
Can salience mask the genuine nociceptive brain activity?
Organiser-Chair: Massimiliano Valeriani (Neurology, Ospedale Pediatrico Bambino Gesú, Rome, Italy)

Physiology of the so-called “Pain Matrix”
Ulf Baumgaertner ( Department of Neurophysiology, Heidelberg University, Germany )
Is the cerebral cortex stimulation painful?
Alexandra Montavont ( Service épilepsie, sommeil et explorations fonctionnelles neuropédiatriques, HFME, Lyon, France )
“Pain Matrix” or “Salience Matrix”? That is the question.
Marina de Tommaso ( Applied Neurophysiology and Pain Unit,  Bari University, Italy )

The network of the cortical areas processing the nociceptive input is commonly known as “Pain Matrix”. In the last decades, new neuroimaging and neurophysiological techniques have increased our knowledge about the physiology of these brain regions. However, the concept itself of “Pain Matrix” has been recently challenged by studies which showed that the cortical activities following a painful stimulation can be evoked by salient non-painful stimuli. The hypothesis has been made that the pattern of cerebral activation, traditionally considered as a marker of pain perception, is a mere expression of the salience of the incoming input, independently of its nociceptive quality. The major aim of this symposium will be to compare the elements in favour of the existence of a specific pain representation within the brain with those which are against this view.

Symposium 10
Applications of novel therapeutic transcranial magnetic stimulation techniques
Organiser-Chair: Letizia Leocani ( Hospital San Raffaele. Milano. Italy )

Single pulse transcranial magnetic and other forms of stimulation for migraine.
Francesca Puledda ( Institute of Neuroscience. King’s College. London. UK )

Transcranial magnetic stimulation has been used as a therapeutic method for more than 30 years. New forms of stimulation have appeared in the recent past that have been selectively used, or have shown the potential for use, in certain disorders. The H-coil produces stimulation centered in the depth of the brain. Letizia Leocani will present and discuss the advantages and disadvantages of it and the disorders in which the deep H-coil may be more suitable. A magnet over the scalp has shown to induce a change in brain excitability. Antonio Oliviero will comment on mode of action and future perspectives for clinical application. Finally, many non-pharmacological types of therapy have been proposed for migraine, including a single-pulse portable TMS. Francesca Puledda will review these therapeutic options.

Professor Franssen will focus on the changes in axonal excitability in common polyneuropathies, and Dr Czesnik will address changes in motor axon excitability that are presumably the result of plastic changes in the properties of the innervating motoneurons. Professor Krarup will focus on disordered Na+ channel function in a validated mouse model of Charcot-Marie-Tooth disease, showing how blocking Na+ channel function can ameliorate the deficit in this model.

Symposium 12
Human brain networks in physiological and pathological aging: graph theory application
Organiser-Chair: Fabrizio Vecchio

Speakers: Fabrizio Vecchio (Italy); Francesca Miraglia (Italy); Paolo Maria Rossini (Italy)

Human behavior and cognition are characterized by engagement of functional distributed networks within the brain. Such networks organization is especially significant in physiological and pathological aging and requires a high degree of intra-modal and inter-modal integration of information flow arriving from several, different and often remote brain sources. These networks dynamically connect adjacent and/or remote cortical neuronal assemblies via cortico-cortical connections. A novel approach, applying concepts from graph theory to neurophysiological data, is a promising new way to characterize brain activity, providing a method to evaluate whether functional connectivity patterns between brain areas resemble the organization of theoretically efficient, flexible or robust networks, based on strength of synchronization of different brain regions. The present proposed symposium is structured in three communication that summarize the possible aspect of connectivity analyses, including EEG graph theory, in both physiological and pathological aging. Specifically, the symposium will be opened by a brief exploration of the modern techniques for the study of brain connectivity. It will be investigated brain connectivity in physiological aging by graph theoretical analysis of resting-state EEG recordings.  Furthermore, it will be illustrated possible way to investigate and diagnosticate neurodegeneration such as Alzheimer’s disease through the study of the brain connectivity modulation

The symposium considers the value of neurophysiological, clinical and provocative tests in the diagnosis of entrapment neuropathies. In the first lecture, experience in combining neurophysiological and clinical techniques will be related. The remaining three talks focus on Carpal Tunnel Syndrome. The first of these compares the value of neurophysiology and provocative tests while the second considers the utility of single fibre EMG in the diagnosis of early CTS. The last lecture will give data on the usefulness of repetitive magnetic stimulation for the alleviation of pain in CTS.

Maeike Zijlmans ( Brain Center Rudolf Magnus, University Medical Center Utrecht, The Netherlands )

The quest for high frequency oscillations (HFO) as biomarkers of epileptogenic tissue has led to ever-increasing frequencies but has cast doubt on their physiological plausibility and their clinical applicability. In this symposium, we will first present controversial physiological recordings to elucidate the physiological origin of HFO and discuss their role in epileptogenicity. Are HFO related to neuronal action potentials or mere effects of signal filtering? To address clinical relevance, we will then ask whether and how HFO can be defined prospectively to predict post-surgical seizure outcome. Is the experts’ agreement on HFO detection sufficient to warrant a more widespread interest in HFO? Here we plan four short presentations (Jiruska, Brazdil, Sarnthein, Zijlmans) followed by a debate between speakers and audience.

Symposium 15
Brain Stimulation – Networks, Semiology, Clinical Value

Networks of ictal symptoms evoked by intracranial stimulation in patients with drug-resistant epilepsy explored through stereo-EEG method
Irina Popa ( Univ. Emergency Hospital of Bucharest, Neurology Dept., Bucharest, Romania )

Session description: High-frequency intracranial stimulation is an essential method for mapping brain function. It is commonly considered that clinical effects result from tissue activation near the stimulation site. However, it may be possible that certain symptoms are the result from activation of broader networks. By using alternating stimulation polarity, we show that it is possible to overcome the stimulation artifact and identify brain networks activated during ~50Hz stimulation in 10 patients undergoing presurgical evaluation for drug-resistant epilepsy using stereo-EEG method. The activation of the networks at stimulation levels evoking a clinical symptom was compared with the below-threshold stimulation, that did not elicit any clinical effects, allowing to evidence a selective recruitment of pathways associated with a particular symptom. The method allowed identification of physiologic networks associated with various somatosensory, motor or language-related symptoms, among others. In addition, we selected patients in which typical ictal symptoms were elicited during stimulation using alternating polarity in several brain regions. Thus, networks underlying ictal symptoms in each patient were identified and then compared to ictal onset activation in order to determine the overlap between epileptogenic and symptomatogenic zone. As early clinical symptoms are the main indicators of the epileptogenic network, this work might play an important role in tailoring depth electrode implantation charts and surgical resections.

Muscle and Nerve Damage in Intensive Care: electrophysiological studies
Organiser-Chair: Mamede De Carvalho ( Portugal )

Speakers: Mamede De Carvalho ( Portugal ), Werner Z’Graggen ( Switzerland ), Jean-Philippe Camdessanche ( France )

Neuromuscular dysfunction is increasingly recognized as a complication in patients cared in the intensive care unit (ICU). This condition is a predictor of mortality risk and is the most frequent cause of prolonged ventilator dependency. Risk factors for both intensive care myopathy and neuropathy are use of steroids, clinical severity, sepsis and multi-organ failure. Muscle lesion spectrum varies from sarcolema inexcitability and myofibrilhar destruction to muscle fibre necrosis. Axonal lesion is a less frequent cause of weakness in the intensive care setting, but can aggravate the manifestations derived from muscle fibre lesion damage. Diagnosis require clinical and laboratory evaluation. Electro- diagnostic testing is essential to evaluate the cause and severity of the intensive care neuromuscular dysfunction. In addition to conventional techniques to assess conduction velocity, spontaneous activity and morphology of motor unit potentials, novel techniques should be considered to investigate these patients. In this session, we aim to stress the importance of threshold technique to address muscle fibre and axonal membrane excitability, and to discuss the relevance of performing neurophysiological tests to investigate diaphragm function. In addition we intend to discuss the strategies to investigate these patients using the available neurophysiological armamentarium.

Symposium 17
Facial Reinnervation and Function

Scientific outlook on the advanced techniques for assessing the re-innervation after muscle transplantation.
Utku S. Yavuz ( Institute of Applied Mechanics, University of Stuttgart. Stuttgart. Germany )

Following up the reinnervation is a remarkable topic in full-face transplantation which usually completes within nine months. On the other hand, reinnervation does not mean to regain the complete function. Recovery of facial expressions improves the nonverbal communication, but reinnervation of muscle and skin is complex. Moreover,  it is predictable to have plastic changes in primary and secondary association cortices following total loss of innervation. Face transplantation patients generally have different backgrounds and exhibit different degrees of sensorymotor improvement. Therefore, each case needs to be treated individually. The complexity of facial nerves and randomness of reinnervation may be responsible for unexpected observations of aberrant reinnervation and synkinesis after facial transplantation. In this symposium, we will present and discuss neurophysiological approach to individualized rehabilitation strategies after full-face transplantation.

Sleep disorder are common affecting a significant part of the population. Central for the diagnose is the polysomnographic (PSG) evaluation which is considered as the gold standard. The technology rely decades of experiments, which however also have proven limitations primary due to the initial definition and manual scoring of the physiological measures. During latest decades significant advances have improved. In this symposium we focus on the medical and technical advantages which have appeared in 1) REM sleep Behavior Disorders (RBD) which are strongly associated with narcolepsy and alfasynucleinopathies, primarily Parkinson’s Disease PD, and 2) narcolepsy with cataplexy which have associated with loss of hypocretinergic neurons in hypothalamus. We will discuss the current neurophysiological findings and evaluation for diagnosing these disorders. We will discuss both the use of traditional electrophysiological methods but also the use of advance diagnostic methods taking the basic disease pathophysiological understanding into consideration.
