Extended Data Fig. 3

Representative multiplexed electrophysiology recordings of control probe (a) and VasES (b) at 7 (I) and 14 (II) days post-implantation. Scale bars, 100 ms (lateral) and 100 µV (vertical). c, Bar chart of chronic electrophysiology recording signal-to-noise ratios (SNRs) of control probe and VasES (details in the Supplementary Note 2), showing that VasES has higher SNRs than control probe on 4–14 days post-implantation. Data includes 77 channels from 3 control probes and 69 channels from 3 VasES probes. Left to right, P = 0.316, **P = 1.63 × 10−3, **P = 8.28 × 10−3, **P = 4.51 × 10−3; two-tailed t-test. Bars represent mean values.
