Abstract

Implanting electrodes for recording the neural signals in the deep brain regions is promising to observe various physiological phenomena, and add a number of their applications. For those purposes, it is important to place the electrodes made of bio-compatible materials in the target regions precisely. This work has discussed the feasibility of titanium wires, which were known for their high bio-compatibility and weak magnetism, as neural electrodes. The titanium and tungsten wires coated with Parylene polymer were implanted in the rat brain. For each electrode, the signal measurement abilities in the acute experiment and the characteristics in magnetic resonance imaging (MRI) scan were confirmed. Our results showed that the recorded signals and the MR images had no remarkable differences in their signals and images property, which suggested possibility of utilizing titanium wires, as well as conventional tungsten wires, for recording neural signals in the deep brain regions.
