Introduction: Visualization of processes that are happening in an organism is implemented by
means of rapid progress of electronics and computer systems. Especially valuable is visualization of
physiological processes in central nervous system as they are short-term, unexplored, and complicated in their mechanism. We propose a new controlling system over the course of neurophysiological
experiment during implantation into a brain of a rat multichannal electrode.
Materials and Methods: Eight channel original steel microelectrode with interspaces
between each conductor. Through the trepanation opening the electrode was placed stereotaxicaly
in motor cortex under narcosis. A chain of devices pre-amplifier, filters, post-amplifier, conductor
and receiver were produced in neurophysiological experiment lab of National Pirogov Memorial
Medical University. Registration of biopotentials is held through analog-to-digital converter on
magnetic carrier at the same time potential from each channel was passed to eight channel amplifier
and then to dynamics placed along the perimeter of a lab.
Discussion results: The same time with visual control over neurons’ biopotentials we
controlled the course of experiment using audiosystem.
Conclusion: The proposed device improves the perception of the experiment course by the
researcher, helps to imagine the spatial arrangement of neurons surrounding the eight channel
electrode and provides new opportunities for assessment of interaction between neurons. |
