Fig. 3From: Biocompatibility and magnetic resonance imaging characteristics of carbon nanotube yarn neural electrodes in a rat modelThickness of neuron-depleted areassurrounding CNTY and control Pt–Ir electrodes. At 1, 6, and 12 weeks after electrode implantation, the thickness of the neuron-depleted layer of brain tissue surrounding the electrodes were compared. * P < 0.05, ** P < 0.01Back to article page
