Nevertheless, the cortical generators underlying the various components of CCEPs in humans have not yet been elucidated. Our aim was to describe the laminar pattern arising under SPES evoked CCEP components (P1, N1, P2, N2, P3) and to evaluate the similarities between N2 and the downstate of sleep slow waves. We used intra-cortical laminar microelectrodes (LMEs) to record CCEPs evoked by 10 mA bipolar 0.5 Hz electric pulses in seven patients with medically intractable epilepsy implanted with subdural grids. Based on the laminar profile of CCEPs, the latency of components is not layer-dependent, however their rate of appearance varies across cortical depth and stimulation distance, while the seizure onset zone does not seem to affect the emergence of components. Early neural excitation primarily engages middle and deep layers, propagating to the superficial layers, followed by mainly superficial inhibition, concluding in a sleep slow wave-like inhibition and excitation sequence.}, year = {2024}, eissn = {2045-2322}, orcid-numbers = {Szabó, Johanna Petra/0000-0001-7690-9171; Wittner, Lucia/0000-0001-6800-0953; Erőss, Loránd/0000-0002-5796-5546; Ulbert, István/0000-0001-9941-9159; Fabó, Dániel/0000-0001-5141-5351} } @misc{MTMT:34428213, title = {Long-term results with the novel anti-seizure medication, cenobamate, in a single center in Hungary}, url = {https://m2.mtmt.hu/api/publication/34428213}, author = {Jordán, Zsófia and Pető, Nóra and Sákovics, Anna and Hajnal, Boglárka Zsófia and Szabó, Johanna Petra and Ujvári, Ákos and Kelemen, Anna and Fabó, Dániel}, unique-id = {34428213}, year = {2023}, orcid-numbers = {Szabó, Johanna Petra/0000-0001-7690-9171; Kelemen, Anna/0000-0003-3942-3409; Fabó, Dániel/0000-0001-5141-5351} } @article{MTMT:34019088, title = {The role of superficial and deep layers in the generation of high frequency oscillations and interictal epileptiform discharges in the human cortex}, url = {https://m2.mtmt.hu/api/publication/34019088}, author = {Fabó, Dániel and Bokodi, Virág and Szabó, Johanna Petra and Tóth, Emília and Salami, Pariya and Keller, Corey J and Hajnal, Boglárka Zsófia and Thesen, Thomas and Devinsky, Orrin and Doyle, Werner and Mehta, Ashesh and Madsen, Joseph and Eskandar, Emad and Erőss, Loránd and Ulbert, István and Halgren, Eric and Cash, Sydney S}, doi = {10.1038/s41598-022-22497-2}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {34019088}, abstract = {Describing intracortical laminar organization of interictal epileptiform discharges (IED) and high frequency oscillations (HFOs), also known as ripples. Defining the frequency limits of slow and fast ripples. We recorded potential gradients with laminar multielectrode arrays (LME) for current source density (CSD) and multi-unit activity (MUA) analysis of interictal epileptiform discharges IEDs and HFOs in the neocortex and mesial temporal lobe of focal epilepsy patients. IEDs were observed in 20/29, while ripples only in 9/29 patients. Ripples were all detected within the seizure onset zone (SOZ). Compared to hippocampal HFOs, neocortical ripples proved to be longer, lower in frequency and amplitude, and presented non-uniform cycles. A subset of ripples (≈ 50%) co-occurred with IEDs, while IEDs were shown to contain variable high-frequency activity, even below HFO detection threshold. The limit between slow and fast ripples was defined at 150 Hz, while IEDs' high frequency components form clusters separated at 185 Hz. CSD analysis of IEDs and ripples revealed an alternating sink-source pair in the supragranular cortical layers, although fast ripple CSD appeared lower and engaged a wider cortical domain than slow ripples MUA analysis suggested a possible role of infragranularly located neural populations in ripple and IED generation. Laminar distribution of peak frequencies derived from HFOs and IEDs, respectively, showed that supragranular layers were dominated by slower (< 150 Hz) components. Our findings suggest that cortical slow ripples are generated primarily in upper layers while fast ripples and associated MUA in deeper layers. The dissociation of macro- and microdomains suggests that microelectrode recordings may be more selective for SOZ-linked ripples. We found a complex interplay between neural activity in the neocortical laminae during ripple and IED formation. We observed a potential leading role of cortical neurons in deeper layers, suggesting a refined utilization of LMEs in SOZ localization.}, year = {2023}, eissn = {2045-2322}, orcid-numbers = {Fabó, Dániel/0000-0001-5141-5351; Szabó, Johanna Petra/0000-0001-7690-9171; Erőss, Loránd/0000-0002-5796-5546; Ulbert, István/0000-0001-9941-9159} } @article{MTMT:33649610, title = {Spectral analysis of after-discharges elicited by intracranial 50 Hz stimulation of epileptic patients}, url = {https://m2.mtmt.hu/api/publication/33649610}, author = {Szabó, Johanna Petra and Hajnal, Boglárka Zsófia and Sákovics, Anna and Erőss, Loránd and Fabó, Dániel}, doi = {10.1016/j.brs.2023.01.632}, journal-iso = {BRAIN STIMUL}, journal = {BRAIN STIMULATION}, volume = {16}, unique-id = {33649610}, issn = {1935-861X}, year = {2023}, eissn = {1876-4754}, pages = {335-335}, orcid-numbers = {Szabó, Johanna Petra/0000-0001-7690-9171; Erőss, Loránd/0000-0002-5796-5546; Fabó, Dániel/0000-0001-5141-5351} } @article{MTMT:34428168, title = {Long-term results with the novel anti-seizure medication, cenobamate, in a single centre in Hungary}, url = {https://m2.mtmt.hu/api/publication/34428168}, author = {Pető, Nóra and Jordán, Zsófia and Hajnal, Boglárka Zsófia and Ujvari, A. and Kelemen, Anna and Fabó, Dániel}, journal-iso = {EUR J NEUROL}, journal = {EUROPEAN JOURNAL OF NEUROLOGY}, volume = {29}, unique-id = {34428168}, issn = {1351-5101}, year = {2022}, eissn = {1468-1331}, pages = {733-733}, orcid-numbers = {Kelemen, Anna/0000-0003-3942-3409; Fabó, Dániel/0000-0001-5141-5351} } @CONFERENCE{MTMT:33632094, title = {Perisomatic inhibition and its relation to epilepsy and to synchrony generation in the human neocortex}, url = {https://m2.mtmt.hu/api/publication/33632094}, author = {Tóth, Estilla Zsófia and Szabó, Gyöngyvér Felicia and Kandrács, Ágnes and Molnár, Orsolya Noémi and Nagy, Gábor and Bagó, Attila György and Fabó, Dániel and Hajnal, Boglárka Zsófia and Rácz, Bence and Wittner, Lucia and Ulbert, István and Tóth, Kinga}, booktitle = {International Neuroscience Meeting, Budapest 2022}, unique-id = {33632094}, year = {2022}, orcid-numbers = {Nagy, Gábor/0000-0001-8831-3340; Fabó, Dániel/0000-0001-5141-5351; Wittner, Lucia/0000-0001-6800-0953; Ulbert, István/0000-0001-9941-9159} } @article{MTMT:33075628, title = {A humán agykéreg elektromos ingerlésével kiváltott válaszok alatti lokális hálózati és egysejt-szintű aktivitásváltozásainak vizsgálata}, url = {https://m2.mtmt.hu/api/publication/33075628}, author = {Hajnal, Boglárka Zsófia and Entz, László and Tóth, Emília and Wittner, Lucia and Ulbert, István and Erőss, Loránd and Fabó, Dániel}, journal-iso = {IDEGGYÓGY SZEMLE PROC}, journal = {IDEGGYÓGYÁSZATI SZEMLE PROCEEDINGS / CLINICAL NEUROSCIENCE PROCEEDINGS}, volume = {7}, unique-id = {33075628}, issn = {2498-6240}, year = {2022}, pages = {18}, orcid-numbers = {Wittner, Lucia/0000-0001-6800-0953; Ulbert, István/0000-0001-9941-9159; Erőss, Loránd/0000-0002-5796-5546; Fabó, Dániel/0000-0001-5141-5351} } @article{MTMT:32801245, title = {Concealment of Allergic Reactions to Alteplase by Face Masks in Non-Communicating Acute Stroke Patients.
