Data to support observation of late and ultra-late latency components of cortical laser evoked potentials
نویسندگان
چکیده
Data are provided to document the presence of late and ultra-late latency components of cortical laser evoked potentials (LEPs) following noxious laser stimulus in Stancak et al. (2015) [3]. The latency components, labeled provisionally as N4, N5, and N6, were observed in 16 healthy human participants who were asked to fully attend their painful and non-painful sensations occurring in association with noxious laser stimulus. Individual laser evoked potential waveforms are provided in support of this observation. Data provided demonstrate the cortical sources of the late and ultra-late laser evoked potentials. The cortical sources of LEPs were reconstructed using the standardized Low Resolution Electromagnetic Tomography (sLORETA) method.

Native-like Event-related Potentials in Processing the Second Language Syntax: Late Bilinguals
Background: The P600 brain wave reflects syntactic processes in response to different first language (L1) syntactic violations, syntactic repair, structural reanalysis, and specific semantic components. Unlike semantic processing, aspects of the second language (L2) syntactic processing differ from the L1, particularly at lower levels of proficiency. At higher L2 proficiency, syntactic violatio...
متن کاملCurrent source density analysis of laser heat-evoked intra-cortical field potentials in the primary somatosensory cortex of rats.
The role of the primary somatosensory cortex in thermal pain perception has been established. However, the cortical circuitry that mediates the thermo-nociceptive information processing has not been elucidated. The aim of present study was to investigate the intracortical synaptic currents in primary somatosensory cortex evoked by short laser pulses and to determine their transmission pathway. ...

Background : To determine the effect of binocular summation on the time domain transient VEP wave's components. Methods : The monocular and binocular transient visual evoked potentials of 21 normally vision volunteers 18 to 24 years (mean ± SD, 20.7 ± 1.9) during a reversing checkerboard stimulus with spatiotemporal frequency of 2.18-4 cpd-Hz were recorded. The amplitude and latency of N75,...
متن کاملAuditory brainstem response, middle latency response, and late cortical evoked potentials in children with learning disabilities.
Auditory evoked potentials (AEPs) and behavioral tests were used to evaluate auditory processing in 10 children aged 7 to 11 years who were diagnosed as learning disabled (LD). AEPs included auditory brainstem responses (ABRs), middle latency responses (MLRs), and late cortical responses (P1, N1, P2, P3). Late cortical responses were recorded using an active listening oddball procedure. Auditor...

This study investigated the tonotopic organization of pure-tone-evoked middle latency auditory evoked potentials (MAEPs) recorded at the auditory cortical surface in unanesthetized gerbils. Multielectrode array recording and multiple linear regression analysis of the MAEP demonstrated different degrees of tonotopic organization of early and late MAEP components. The early MAEP components P1 and...
