To propose a framework distinguishing between spatial patterning mechanisms and a calcium-dependent execution layer that stabilizes coordinated behavior across biological systems in the context of Autism Spectrum Disorder (ASD).
Approach:
Framework Proposal: The framework distinguishes between spatial patterning mechanisms that establish tissue geometry and a coordination-dependent execution layer that stabilizes coherent biological behavior.
Mechanisms of Coordination: The model emphasizes intracellular Ca²+ signaling, particularly endoplasmic reticulum Ca²+ release via inositol 1,4,5-trisphosphate receptors (ITPRs), as a key mechanism for stabilizing coordinated execution.
Key Findings:
ASD is characterized by altered neural timing and synchronization despite preserved neuroanatomy.
Coordination-dependent processes may be affected across multiple biological systems, including gastrointestinal and neural crest development.
Partial disruption of calcium-dependent coordination could impair synchronization without affecting structural organization.
Interpretation:
The proposed framework is not a universal explanation for ASD but a testable model for coordination-related phenotypes across systems.
Limitations:
The framework does not imply a singular causal pathway for all forms of ASD.
It is based on the premise that diverse genetic, epigenetic, metabolic, immunologic, and environmental factors contribute to ASD.
Conclusion:
The framework serves as an organizational and hypothesis-generating model for understanding coordination-dependent biology in ASD.
