Area of Science:

  • Neuroscience
  • Molecular Biology
  • Systems Neuroscience

Context:

  • The striatum, a key limbic-motor interface, receives complex cortical and subcortical inputs.
  • Intermingled synaptic inputs historically hindered selective neuronal population studies.
  • Optogenetics offers a revolutionary tool for dissecting intricate neural circuits.

Purpose:

  • To review the application of optogenetics in studying striatal circuits.
  • To introduce optogenetic tools like channelrhodopsin and halorhodopsin.
  • To categorize optogenetic approaches for analyzing neural connectivity and function.

Summary:

  • Optogenetics enables selective activation/inhibition of neuronal populations in vivo.
  • Techniques include activating identified synaptic inputs and convergent inputs.
  • Applications extend to cell identification for in vivo recordings.

Impact:

  • Optogenetic analysis provides novel insights into striatal circuit function.
  • Enables previously impossible experiments in intact brain systems.
  • Resolves the functional roles of complex neural circuitry.
