Relevant results were obtained by a combination of spectral analysis and manual review. High-frequency oscillations (HFO) were quantified across different SOP by an automatic detection method.Results: We identified six SOP according to previous work by Lagarde et al.: (1) Low-voltage fast activity (LVFA); (2) Rhythmic spikes followed by LVFA; (3) Burst of spikes followed by LVFA; (4) Periodic spikes or spike-wave followed by LVFA; (5) Rhythmic spike or spike-wave; (6) Theta or alpha sharp activity. Notably, Periodic spikes or spike-wave followed by LVFA had a high prevalence in all seizures (37 %). A significant association was established between Periodic spike followed by LVFA and HS-mTLE (P < 0.05). Furthermore, the counts of ripples and fast ripples were significantly higher in SOP displaying LVFA compared to those that did not (P < 0.05). Rhythmic spikes followed by LVFA had the best prognosis (92 % seizure-free), while Burst of spikes followed by LVFA were linked to poorest prognosis (67 % SF).Conclusion: HS-mTLE and non-HS-mTLE exhibit distinct SOP characteristics, which can offer valuable prognostic insights with a more informative interpretation of ictal iEEG for clinical guidance.","PeriodicalId":19134,"journal":{"name":"Neurophysiologie Clinique/Clinical Neurophysiology","volume":"55 1","pages":"103040"},"PeriodicalIF":2.7,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142927699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patient data were collected from existing medical records. The study aimed to analyze pre-existing electrophysiological data, including abnormal muscle response (AMR) and facial synkinesis, focusing on parameters such as AMR latency, amplitude, and duration.Results: In the HFS group, AMR could be induced in all patients, with synkinesis present in 31.8 %. In the PFPS group, AMR and synkinesis were induced in 79.5 % and 100 % of patients, respectively. Compared with the PFPS group, the HFS group had a shorter AMR latency and higher amplitude (P < 0.05). The duration of the AMR did not significantly differ between the two groups (P > 0.05). Synkinesis in the HFS group was typically accompanied or followed by an involuntary spasm episode, but not every eye closure or pouting led to synkinesis. In contrast, synkinesis in the PFPS group occurred with every voluntary movement and was synchronized with these movements.Conclusions: Patients with HFS and PFPS may exhibit similar clinical symptoms. Neurophysiological tests, particularly electromyography, provide valuable information for the differential diagnosis of HFS and PFPS.","PeriodicalId":19134,"journal":{"name":"Neurophysiologie Clinique/Clinical Neurophysiology","volume":"55 2","pages":"103019"},"PeriodicalIF":2.7,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey captured institutional characteristics, geographic distributions, intracranial EEG utilization, and barriers to SEEG. Respondents were representative epilepsy centers across the region.Results: Four epilepsy centers with established intracranial/ SEEG and two centers from a country without any access to SEEG participated. The responses identified that 1. Access to SEEG remained highly restricted across the region with an estimated one capable epilepsy center per 100 million people; 2. The region includes over half a billion people living in countries with no access to SEEG; 3. Staffing/ financial constraints were universal factors that limited growth of services or development of new services; 4. SEEG numbers have plateaued as a result of these challenges.Conclusion: The study puts into real numbers the challenges faced by the region in accessing SEEG.

Along with homeostatic and cognitive control, it forms part of the control of food intake (hedonic control), and does not only correspond to the pleasure that can be described of food intake. There are many factors that cause variations in eating pleasantness between individuals, such as age, sex, culture, co-morbidities, treatments, environmental factors or the specific characteristics of foods. The control of food intake is based on four determinants: conditioned satiety, the reward system, sensory specific satiety and alliesthesia. These four determinants follow one another over time, in the per-prandial and inter-prandial periods, and complement one another. There are many cerebral areas involved in the hedonic control of food intake. The most involved brain areas are the orbitofrontal and anterior cingulate cortices, which interact with deep neural structures (amygdala, striatum, substantia nigra) for the reward circuit, with the hippocampi for memorising pleasant foods, and even with the hypothalamus and insula, brain areas more recently involved in the physiology of food pleasantness. Changes in brain activity secondary to modulation of food pleasantness can be measured objectively by recording taste-evoked potentials, an electroencephalography technique with very good temporal resolution.","PeriodicalId":19134,"journal":{"name":"Neurophysiologie Clinique/Clinical Neurophysiology","volume":"55 1","pages":"103031"},"PeriodicalIF":2.7,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142792083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, surgical outcomes remain varied, often influenced by lesion type and location. Traditional lesion-centric approaches may overlook the complex organization of the epileptogenic zone (EZ), which often extends beyond the visible lesion, emphasizing the need for comprehensive presurgical evaluations like stereo-electroencephalography (SEEG) in some cases. This article delves into the concept of epileptogenic networks, moving beyond the notion of a lesional epileptic focus. Through SEEG, three primary network types have been identified: the Epileptogenic Zone Network (EZN), characterized by regions with heightened epileptogenicity and seizure initiation; the Propagation Zone Network (PZN), involving regions with delayed and less intense epileptic activity; and Non-Involved networks (NI). Quantitative measures, such as the epileptogenicity index (EI), aid in delineating these networks, revealing that EZN can be focal or networked, with the latter being more prevalent.</div><div>The relationship between epilepsy-associated lesions and network organization is complex. Intrinsically epileptogenic lesions, like focal cortical dysplasia and periventricular nodular heterotopias, often generate epileptiform activities but may still involve broader epileptogenic networks. Non-intrinsically epileptogenic lesions, such as cavernomas and post-stroke lesions, typically lack inherent neuronal activity but can facilitate the development of extensive epileptogenic networks.</div><div>Understanding the intricacies of these networks is crucial for optimizing surgical interventions. Recognizing that lesions may represent just one node within a broader epileptogenic network underscores the importance of comprehensive SEEG evaluations to achieve better surgical outcomes.</div></div>","PeriodicalId":19134,"journal":{"name":"Neurophysiologie Clinique/Clinical Neurophysiology","volume":"54 6","pages":"Article 103023"},"PeriodicalIF":2.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
