TL;DR: The fully integrated functionality and small size of Neuropixels probes allowed large populations of neurons from several brain structures to be recorded in freely moving animals and opens a path towards recording of brain-wide neural activity during behaviour.

TL;DR: Rats repeatedly ran through a sequence of spatial receptive fields of hippocampal CA1 place cells in a fixed temporal order, consistent with evidence that the hippocampus is crucial for spatial learning in rodents and the formation of long-term memories of events in time in humans.

TL;DR: This work proposes a mechanism by which a temporal code can be generated through an interaction between an asymmetric rate code and oscillatory inhibition, and the resulting spike timing satisfies the temporal order constraints of hebbian learning.

TL;DR: A suite of electrophysiological tools comprising a miniaturized high-density probe, recoverable chronic implant fixtures, and algorithms for automatic post hoc motion correction are demonstrated, enabling an order-of-magnitude increase in the number of sites that can be recorded in small animals, such as mice, and the ability to record from them stably over long time scales.

TL;DR: In this paper, the authors used whole-cell recording in freely moving rats exploring a novel maze, and observed differences in intrinsic cellular properties and input-based sub-threshold membrane potential levels underlying this division into place and silent cells.
