Background:

Existing Brain-Computer-Interface (BCI) systems often face limitations with constant voltage stimulators.
Rat-robot navigation research requires precise and controllable neural stimulation methods.

Purpose of the Study:

To develop and characterize a novel remote stimulator for rat-robot navigation utilizing Brain-Computer-Interface (BCI) technology.
To overcome the limitations of constant voltage stimulators by implementing a constant current output.
To evaluate the effects of varying current stimulation levels on rat behavior in the dorsolateral periaqueductal gray (dlPAG) area.

Main Methods:

Development of a miniaturized (32 mm*25 mm*6mm, ~20 g) five-channel constant current stimulator.
Integration of a power supply, micro control unit (MCU), constant current source, and Bluetooth transceiver.
Characterization of electrical parameters in three rats with varying post-surgery recovery times.
Application of increasing current stimulations to the dorsolateral periaqueductal gray (dlPAG) area.

Main Results:

The developed stimulator provides a constant current output ranging from 0 to 1000 µA.
The device's performance and electrical parameters were successfully characterized across multiple subjects.
Initial behavioral responses to dlPAG current stimulation were observed and recorded.

Conclusions:

The developed constant current remote stimulator represents an advancement for BCI-based rat-robot navigation.
This technology offers improved control and precision compared to previous constant voltage systems.
Further research can explore the behavioral outcomes of targeted neural stimulation for navigation tasks.
