Animal models are crucial for brain-machine interfaces (BMIs) to help patients. Researchers reviewed rhesus monkey models and suggest exploring diverse alternatives for next-generation BMI systems.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Rehabilitation Technology

Background:

  • Brain-machine interfaces (BMIs) translate neural signals into control for assistive devices.
  • Animal models, particularly rhesus monkeys, have been vital for developing current BMIs.
  • Advancing to next-generation BMIs requires evaluating suitable animal models for broader patient applications and enhanced performance.

Purpose of the Study:

  • To review existing rhesus monkey models used in BMI research.
  • To identify and describe complementary animal models for BMI development.
  • To address the need for diverse animal models that mimic various neurological conditions.

Main Methods:

  • Review of four established rhesus monkey models in BMI research.
