Area of Science:

  • Neuroscience
  • Neuroanatomy
  • Systems Neuroscience

Context:

  • The basal ganglia, or central grey nuclei, are crucial for motor control and learning.
  • Understanding their complex anatomical and functional organization is key to deciphering neurological disorders.

Purpose:

  • To provide a comprehensive overview of the basal ganglia system's anatomical organization.
  • To review the historical development and evolution of functional models of the basal ganglia.
  • To synthesize recent advancements and ongoing debates in basal ganglia research.

Summary:

  • The review begins by outlining the macroscopical, hodological, and cytological properties of the basal ganglia.
  • It then examines major functional models proposed since the 1980s, including convergent, parallel, dual-circuit, and current models.
  • Recent models and critiques published since the 1990s are also summarized, offering a historical perspective on systems neuroscience.

Impact:

  • This work provides a foundational understanding for researchers and clinicians studying basal ganglia function and dysfunction.
  • It facilitates the integration of anatomical data with functional models in neuroscience.
  • The review serves as a valuable resource for understanding the progression of thought in basal ganglia research over several decades.
