测量跨时间尺度的神经处理动态需要跟踪数千个单个神经元在毫秒和数月内的尖峰。为了满足这一需求,我们引入了Neuropixels 2.0探头以及新的分析算法。该探针有超过5,000个位点,并被小型化,以促进小型哺乳动物的慢性植入,并在不受限制的行为期间进行记录。在六个实验室的小鼠和大鼠中可靠地获得了长时间尺度的高质量记录。改进的位点密度和排列结合新的数据处理方法,可以对大脑运动进行自动事后校正,允许对相同的神经元进行两个多月的记录。这些探针和算法能够在自由行为期间从数千个位点进行稳定的记录,即使是在小动物(如小鼠)中。
Measuring the dynamics of neural processing across timescales requires following the spiking of thousands of individual neurons over milliseconds and months. To address this need, we introduce the Neuropixels 2.0 probe together with novel analysis algorithms. The probe has over 5,000 sites and is miniaturized to facilitate chronic implants in small mammals and for recording during unrestrained behavior. High quality recordings over long timescales were reliably obtained in mice and rats in six laboratories. Improved site density and arrangement combined with new data processing methods enable automatic post-hoc correction for brain movements, allowing recording from the same neurons for over two months. These probes and algorithms enable stable recordings from thousands of sites during free behavior even in small animals such as mice.
