幼年猪群渐进性脑缺血多模式病理生理学数据集的更新：听觉、感觉和高频感觉诱发电位
Update on the multimodal pathophysiological dataset of gradual cerebral ischemia in a cohort of juvenile pigs: auditory, sensory and high-frequency sensory evoked potentials
摘要：
我们将幼年猪在不同的镇静、缺血和恢复状态下的脑电活动的自发电位（EP）数据集扩展为皮层电图（ECoG）和丘脑电图（EThG）。该EP数据集包括三种刺激范式：听觉（AEP，40和2000 Hz），感觉（SEP，左和右上颌神经）和高频振荡（HFO）SEP。这允许在这些条件下推导出皮质丘脑通信的脑电图（EEG）生物标志物。数据集以2000 Hz的全频带采样形式呈现。我们为镇静、缺血和恢复状态的诱发反应提供了技术验证。这个扩展的数据集现在允许在记录的模态中自发和诱发活动之间的相互推断。未来对该数据集的研究可能有助于开发新的大脑监测技术，这将有助于预防神经损伤。
英文摘要：
We expand from a spontaneous to an evoked potentials (EP) data set of brain electrical activities as electrocorticogram (ECoG) and electrothalamogram (EThG) in juvenile pig under various sedation, ischemia and recovery states. This EP data set includes three stimulation paradigms: auditory (AEP, 40 and 2000 Hz), sensory (SEP, left and right maxillary nerve) and high-frequency oscillations (HFO) SEP. This permits derivation of electroencephalogram (EEG) biomarkers of corticothalamic communication under these conditions. The data set is presented in full band sampled at 2000 Hz. We provide technical validation of the evoked responses for the states of sedation, ischemia and recovery. This extended data set now permits mutual inferences between spontaneous and evoked activities across the recorded modalities. Future studies on the dataset may contribute to the development of new brain monitoring technologies, which will facilitate the prevention of neurological injuries.
