My master degree annual work was to make characterizing measurements of a brain probe, made for solving a current brain scientist’s interest. The brain researchers of Research Centre for Natural Sciences, Hungarian Academy of Sciences (HAS) are investigating the temperature dependence of transient brain signals in mice. For this purpose, a new recording electrode has been manufactured in the Institute for Technical Physics & Material Sciences, Centre for Energy Research, HAS. Its innovative advantage is that the device has three different functions integrated on a single substrate: electrophysiology, temperature measurement and heating.
In my work, I briefly introduce the brain researchers’ goals and specifications, the conditions of the electrode’s usage, and related technical solutions. I explain the technology of the electrode fabrication. I describe the theoretical basics of my fulfilled measurements (thermal calibrations, EIS). I detail applied experimental methods and finally present the results. In the appendix, the applied Matlab codes can be read.
