Neuropixels single-mouse LFP data

NWB 格式的单鼠标 Neuropixels 记录（尖峰和 LFP）。 Klein, N., Siegle, JH, Teichert, T. 和 Kass, RE 的论文“基于高斯过程电流源密度的神经活动的跨种群耦合”中使用的数据集（预印本：https://arxiv.org /abs/2104.10070)。该数据是 Allen Brain Observatory Neuropixels 数据集的一部分（©2019 Allen Institute for Brain Science，可从 https://portal.brain-map.org/explore/circuits/visual-coding-neuropixels 获得）。六个 Neuropixels 探针同时通过视觉皮层、海马、丘脑和中脑插入。在每个探头上，从多达 374 个电极位置记录 LFP 数据，以跨越两个空间维度的棋盘布局：四列间隔 16 微米，行之间间隔 20 微米。在应用 1000 Hz 低通滤波器后，以 2500 Hz 采集 LFP 数据。基于单位密度的降低以及生理特征（例如海马中升高的 theta 带活动）手动识别区域之间的边界。没有区域标签的 LFP 电极不包括在分析中。可以通过 AllenSDK 或 DANDI 存档 https://dandiarchive.org/dandiset/000021/draft 访问该鼠标的尖峰训练和下采样 LFP 数据（主题 ID：730760270；会话 ID：755434585）。用于此分析的原始 LFP 数据作为 Allen Brain Observatory AWS 公共数据集的一部分提供 https://registry.opendata.aws/allen-brain-observatory/。

Single-mouse Neuropixels recordings (spikes and LFP) in NWB format. The dataset used in the paper "Cross-population coupling of neural activity based on Gaussian process current source density" by Klein, N., Siegle, JH, Teichert, T. and Kass, RE (preprint: https://arxiv.org/abs/2104.10070). This data is part of the Allen Brain Observatory Neuropixels dataset (©2019 Allen Institute for Brain Science, available at https://portal.brain-map.org/explore/circuits/visual-coding-neuropixels). Six Neuropixels probes were inserted simultaneously through the visual cortex, hippocampus, thalamus, and midbrain. On each probe, LFP data was recorded from up to 374 electrode positions arranged in a checkerboard layout spanning two spatial dimensions: four columns spaced 16 μm apart, with rows separated by 20 μm. LFP data was acquired at 2500 Hz after applying a 1000 Hz low-pass filter. Boundaries between brain regions were manually identified based on reduced unit density and physiological characteristics (e.g., elevated theta-band activity in the hippocampus). LFP electrodes without regional labels were excluded from the analysis. Spike trains and downsampled LFP data for this mouse (subject ID: 730760270; session ID: 755434585) can be accessed via the AllenSDK or the DANDI archive at https://dandiarchive.org/dandiset/000021/draft. The raw LFP data used for this analysis is available as part of the Allen Brain Observatory AWS public dataset at https://registry.opendata.aws/allen-brain-observatory/.
