Treating Brain Diseases with Brain-Machine Interactive Neuromodulation and NVIDIA Jetson
Summary
Brain-Machine Interactive Neuromodulation (BMINT) is a groundbreaking technique that combines neural sensing, machine learning algorithms, and real-time electrical stimulation to treat brain diseases such as Parkinson’s, epilepsy, and depression. The BMINT research tool, powered by NVIDIA Jetson, has achieved significant advancements in precision and personalized electronic medicine. This article explores the main ideas behind BMINT and its potential to revolutionize brain disease treatment.
Understanding Neuromodulation
Neuromodulation is a technique that enhances or restores brain function by directly intervening in neural activity. It is commonly used to treat conditions like Parkinson’s disease, epilepsy, and depression. The shift from open-loop to closed-loop neuromodulation strategies enables on-demand modulation, improving therapeutic effects while reducing side effects.
The Brain-Machine Interactive Neuromodulation Research Tool
The BMINT research tool is designed to address the challenges of real-time neural decoding and encoding. It consists of three main hardware modules:
- Recording: Includes eight channels for recording neurophysiological signals with a 24-bit amplitude resolution and a 2000 Hz sampling frequency.
- Computing: Features various I/O ports to deliver control commands to interface with other neuromodulation devices, such as transcranial magnetic stimulation (TMS) and ultrasonic stimulation.
- Stimulation: Delivers 2-channel constant current electrical stimulation, with pulse parameters (amplitude, frequency, and pulse width) adjusted in real time.
The Role of NVIDIA Jetson
The researchers chose the NVIDIA Jetson platform as the computing module due to its public pretrained AI model libraries, pretrained AI models (such as NVIDIA NGC, TorchVision, and TensorFlow Hub), and various optimization and acceleration tools (such as CUDA, cuDNN, and NVIDIA TensorRT) for custom-trained AI models. The Jetson Nano developer kit was selected for its edge AI computing capability and compact form factor, low power consumption.
Performance and Results
The integration of the Jetson Nano significantly boosted computational efficiency, achieving a 14.77x increase compared to CPU usage alone. The BMINT tool demonstrated a system time delay of 2.829 ± 0.057 ms, allowing for precise cycle-by-cycle phase modulation in treating brain diseases.
In a simulated online demonstration, the BMINT showcased its capability in real-time closed-loop neuromodulation for epilepsy, achieving a sensitivity of 96.16 with a false positive rate of 1.42. Such performance is critical in optimizing algorithms for better sensitivity and specificity during epilepsy treatment.
The Future of Brain Disease Treatment
The BMINT tool represents a significant advancement in intelligent closed-loop neuromodulation, enabling precise neural sensing and electrical stimulation. Its ability to achieve low system time delays and integrate machine learning algorithms efficiently makes it a promising solution for personalized electronic medicine.
