Romanski (2004)

Core argument: The primate prefrontal cortex is organized by domain specificity rather than modality specificity. Two anatomically distinct PFC regions process different types of information (spatial vs. object identity), each receiving converging inputs from both visual and auditory cortices. This makes the organization cross-modal (domain-specific), not unimodal.

Figure 1 (the figure cited in the thesis, pp. 423): Shows macaque lateral brain with:

  • dlPFC (areas 46, 8a, 8b) receiving blue (visuospatial from parietal areas 7a, 7ip) and green (auditory-spatial from caudal STG/parabelt) arrows — both targeting the same prefrontal spatial domain
  • vlPFC (areas 45, 12 lateral, 12 orbital) receiving orange (inferotemporal — visual objects/faces) and yellow (anterior auditory association cortex — vocalizations/sound identity) arrows — both targeting the same object-processing domain
  • Figure credit: “Schematic adapted, with permission, from ‘Patricia Goldman-Rakic: A Remembrance,’ by A. Arnsten, 2003, Neuron, 40, p. 467.” — this explains why Arnsten (2003) is mentioned in the thesis figure caption

Key findings:

  • dlPFC (areas 46, 8a, 8b): receives visuospatial input from posterior parietal cortex (7a, 7ip) AND auditory-spatial input from caudal superior temporal cortex and parabelt. Neurons here respond to the spatial location of visual AND auditory targets.
  • vlPFC (areas 45, 12 lateral, 12 orbital): receives visual object input from inferotemporal cortex AND auditory object input from anterior auditory association cortex (vocalizations). Neurons here respond to complex sounds and object identity across modalities.
  • Key claim: “domain should refer to any sensory modality that registers information relevant to that domain” — e.g., both vision and audition feed into the spatial domain (dlPFC) and the object domain (vlPFC).
  • Directly contradicts modality-specific organization; supports supramodal or domain-general PFC architecture.

Mapping to thesis:

  • The macaque dlPFC ≈ human FEF (caudal MFG, areas 8/6 border) — spatial domain controller
  • The macaque vlPFC ≈ human IFJa (areas 45/6 junction) — object/identity domain controller
  • The domain specificity in primates is the theoretical foundation for the supramodal claim in Sections 1.1.1, 2.0, and 5.1.4

Relevance to thesis:

  • Cite in §2.0 Theoretical Background as the foundational primate evidence for domain-specific (not modality-specific) PFC organization
  • The figure (Figure 1, Romanski 2004) shows how both auditory and visual spatial inputs converge on the dorsal PFC — directly motivates the FEF hypothesis
  • Supports the argument that the FEF/IFJa dissociation found in humans (Bedini & Baldauf, 2021) has primate anatomical precedent
