Main Results:

  • Modern segmental thinking provides a robust framework for interpreting complex forebrain data.
  • This paradigm facilitates pitfall-free morphological analysis.
  • It offers advantages over traditional viewpoints by clarifying underlying assumptions.

Conclusions:

  • Segmental thinking represents a significant advancement in understanding forebrain organization.
  • This paradigm enhances the interpretation of neurodevelopmental and evolutionary data.
  • Future research should leverage this framework for a more cohesive understanding of the forebrain.
