BCIwiki (bciwiki.com) — SpikeGadgets has introduced Neuropixels-compatible wireless dataloggers that allow animals to carry the entire recording system untethered, enabling high-density neural recordings during natural behavior. Over the past year, four studies have used this setup in freely moving or flying animals, yielding new insights.
According to SpikeGadgets' website, the Yartsev lab at UC Berkeley used a SpikeGadgets Neuropixels Datalogger Headstage weighing about 19 g to record wirelessly from freely flying Egyptian fruit bats, marking the first wireless Neuropixels recording of large-scale neural activity in a freely flying mammal. At Janelia Research Campus, the Karpova lab used the hardware to record from hundreds of neurons in the rostral anterior cingulate cortex of freely moving rats. Two independent groups at Western University and UC San Diego used Neuropixels probes and SpikeGadgets dataloggers to study vocal communication in freely moving marmosets.
SpikeGadgets has also introduced next-generation products: the Bennu Neuropixels Datalogger supports Neuropixels 1.0 and 2.0 probes, and the Satori NHP Neuropixels Datalogger is designed for freely moving large-brain models, including non-human primates.
