Neuropixels data for paper "Multichannel neural spike sorting with spike reduction and positional feature"

This is the data of a mouse with the following description. Neural data were recorded by Neuropixels Phase 3A prototype probes (Jun et al. 2017) in awake mice, following procedures described in detail elsewhere (Denman and Reid 2019). All animal procedures were approved by the Allen Institute for Brain Science Institutional Animal Care and Use Committee (IACUC). Mice in this study were male C57BL/6J aged 60 – 182 days. Briefly, animals were first outfitted with a permanently attached head fixation device and habituated to the recording apparatus. On the day of recording, an approximately 2x2 mm cranial window was opened over the primary visual cortex, and a Neuropixels probe lowered through cortex, subiculum or hippocampus, and ventral thalamic structures. Probes were inserted with piezoelectric manipulators at 50 - 100 μm / minute to their target depth. Increased neural activity was elicited with visual stimuli, which consisted of full-field flicker, repeated presentation of natural images, and a repeated naturalistic movie clip.
