Background:

Neural prosthetic devices require robust animal models for development and testing.
Existing models may not fully replicate the complexity of human neural systems or device integration challenges.

Purpose of the Study:

To establish a comprehensive system for neural prosthetic device development and testing using a domestic pig model.
To introduce a novel stereotactic frame and a wireless microsystem for neural data acquisition.

Main Methods:

Development of a specialized stereotactic frame for precise pig brain implantation.
Implantation of an ultra-low power, 16-channel wireless neural microsystem.
Utilizing a new data acquisition paradigm for actuator control and neural recording.

Main Results:

Successful implantation of the neural microsystem in pigs using the novel stereotactic frame.
Collection of neural data over a 5-week period, demonstrating clear single-unit spiking activity.
Validation of the wireless infrared telemetry link for broadband data transmission.

Conclusions:

The domestic pig is a viable and effective model for neural prosthetic research.
The developed system facilitates the advancement of neural prosthetic device technology.
This platform supports future research in brain-computer interfaces and neuroprosthetics.
