Latest Neuropixels probes can track neurons over weeks
A new generation of miniature recording probes can track the same neurons inside tiny mouse brains over weeks and even months.
LEUVEN (Belgium), April 20, 2021 The new tools build on the success of the original Neuropixels probes released in 2017 and currently used in more than 400 labs. Neuropixels 2.0 are much smaller about a third the size of their predecessors. They’re designed to record the electrical activity from more individual neurons and have the unique ability to track this activity over extended time periods. That makes them especially useful for studying long-term phenomena like learning and memory in small animals such as mice, says Tim Harris, a senior fellow at HHMI’s Janelia Research Campus who led the project. Harris and his colleagues describe the advance in a paper published online April 16 in the journal
