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.
Journal ArticleDOI
An implantable 455-active-electrode 52-channel CMOS neural probe
Carolina Mora Lopez,Alexandru Andrei,Srinjoy Mitra,Marleen Welkenhuysen,Wolfgang Eberle,Carmen Bartic,Robert Puers,Refet Firat Yazicioglu,Georges Gielen +8 more
TL;DR: The main tradeoff in neural probe design is between minimizing the probe dimensions and achieving high spatial resolution using large arrays of small recording sites.
Journal ArticleDOI
A Neural Probe With Up to 966 Electrodes and Up to 384 Configurable Channels in 0.13 $\mu$m SOI CMOS

TL;DR: A 384-channel configurable neural probe for large-scale in vivo recording of neural signals and results show a total input-referred noise of 6.4%, dual-band recording and a 171.6 Mbps digital interface.
Journal ArticleDOI
