Fig. 5From: Electrophoretic deposition of ligand-free platinum nanoparticles on neural electrodes affects their impedance in vitro and in vivo with no negative effect on reactive gliosisTotal spectral power of the local field potential recorded in the subthalamic nucleus of the implanted animals. Data are means + SEM for the differently coated (nanoparticles smaller than 10 nm; 50 nm; mixture of both) and uncoated (NoNP) electrodes. Significant difference between groups is indicated with asterisk (*; ANOVA on Ranks, p < 0.05)Back to article page
