DEVICE FOR SIMULTANEOUSLY READING MULTIPLE ELECTROENCEPHALOGRAPHIC AND BIOCHEMICAL SIGNALS

Abstract

The present invention relates to a device that allows the reading of electroencephalographic and biochemical signals in rodent brains. This is achieved using supports with three-axis rotation for the electrodes and microdialysis cannulas, manually adjustable mechanisms, and air-expandable sections. The mechanism is manually operated by sliding elements with a locking mechanism, and includes an air-expanding element for the vertical insertion of the electrodes. Additionally, it has the capacity to simultaneously introduce microdialysis cannulas to obtain cerebrospinal fluid for subsequent biochemical signal analysis while simultaneously acquiring electroencephalographic signals.
