Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Neural Engineering

Background:

  • Artificial stimulation has been a cornerstone of neuroscience research for 150 years.
  • Electrical and optogenetic stimulation techniques are being developed for neuroprosthetic applications.
  • These technologies aim to replace lost sensory inputs and introduce novel information into the nervous system.

Purpose of the Study:

  • To review the progress in utilizing artificial stimulation to convey information to the cerebral cortex.
  • To explore the challenges and future potential of artificial neural information transfer.

Main Methods:

  • Classification of artificial stimulation strategies into biomimetic and arbitrary approaches.
  • Biomimetic stimulation seeks to replicate natural neural activity patterns.
  • Arbitrary stimulation assigns random meanings to stimuli, relying on neural plasticity for learning.

Main Results:

  • Examining advancements in injecting information into the cerebral cortex via artificial stimulation.
  • Highlighting the distinct mechanisms and learning requirements of biomimetic versus arbitrary stimulation.

Conclusions:

  • Artificial stimulation holds significant promise for neuroprosthetic development.
  • Both biomimetic and arbitrary approaches present unique challenges and opportunities for future research in neural information processing.
