Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Rehabilitation Technology

Background:

  • Paralysis and amputation significantly impair quality of life and independence.
  • Existing assistive technologies often rely on motor signals, limiting their application.
  • Cognitive neural prosthetics (CNPs) offer a novel approach by decoding cognitive states.

Purpose of the Study:

  • To review high-level cortical signals applicable to cognitive neural prosthetics (CNPs).
  • To explore the definition and application of CNPs based on cognitive function extraction.
  • To discuss the potential of parallel signal extraction from multiple cortical areas.

Main Methods:

  • Review of high-level cortical signals including intention, motor imagery, decision making, and attention.
  • Analysis of signal extraction from various cortical areas for CNP applications.
  • Examination of parallel signal processing from multiple cortical regions.

Main Results:

  • CNPs utilize cognitive states (e.g., intention, decision-making) rather than motor execution signals.
  • The application of CNPs is defined by the cognitive function decoded, not the specific cortical region.
  • Parallel signal extraction from multiple cortical areas can expand CNP capabilities.

Conclusions:

  • CNPs represent a versatile method for assisting individuals with paralysis and amputations.
  • The advancement of CNPs relies on understanding neural processes of cognition and neural circuit functions.
  • Future CNP development can leverage parallel processing and a deeper understanding of cognitive neuroscience.
