Synthetic Cognitive Augmentation Network
A comprehensive AI framework that mirrors human cognition through modular agents, psychometric alignment, and neuromorphic computing—creating personalized, energy-efficient cognitive support systems.
Five foundational advances in cognitive AI architecture and personalization
SCAN is not just one technology—it's a complete ecosystem of interconnected AI systems designed to augment human cognition. Think of it as a neural network that thinks like you do, learns from you, and helps you make better decisions.
Traditional AI systems are monolithic—one giant model trying to do everything. The human brain doesn't work that way. Your prefrontal cortex has specialized regions: one for planning, one for emotional regulation, one for risk assessment. SCAN mirrors this biological reality.
The ecosystem consists of four integrated components, each solving a specific challenge in building truly intelligent, personalized AI systems.
The foundation—a modular cognitive architecture with specialized agents that work like different regions of your brain
The intelligent layer—adaptive agents that learn from your feedback and personalize to your needs
The alignment tool—a questionnaire that maps your cognitive style to agent behaviors
The efficiency research track: converting transformers to spiking networks, with the energy savings still to be demonstrated
SCAN is the architectural foundation—a modular AI system where specialized agents work together like regions of the human prefrontal cortex. Instead of one model doing everything poorly, five focused agents excel at specific cognitive tasks.
SCANUE is the evolution—where SCAN agents become truly adaptive. Each agent is fine-tuned for its cognitive function, learns from human feedback, and continuously improves. It's SCAN with a memory and the ability to grow.
SCANAQ is the personalization engine—a 36-item psychometric assessment that profiles your cognitive style across 8 dimensions. It tells SCANUE how to adapt its agents to match the way you think and decide.
STAC is the efficiency research track: a framework for converting pretrained transformers into spiking neural networks. With spiking off, the conversion reproduces the source model exactly. With spiking on, the operation-count projection for the current design is worse than the dense model, and no energy has been measured on neuromorphic hardware. The measured results are in the repository.
First, you take the questionnaire. SCANAQ assesses your cognitive style across 8 dimensions. Then, each dimension configures a specific PFC agent. For example, your Executive Functioning score tells the DLPFC agent how much structure you want around tasks, so it can provide responses that match your natural planning style. This personalization happens for all 8 dimensions across all 5 agents.
Each component plays a specific role, and together they create a cognitive augmentation system that's both powerful and personal.

The SCAN ecosystem is described in three peer-reviewed book chapters: one with Springer Nature and two with IGI Global.
Introduces the core SCAN framework—modular AI agents modeled after prefrontal cortex regions. Demonstrates biological plausibility and introduces SCANUE, SCANAQ, and STAC as future components.
Operationalizes SCAN as SCANUE—fine-tuned agents for each prefrontal region, curated training datasets, and human-in-the-loop feedback for continuous realignment. Introduces SCANAQ as an upcoming instrument.
Presents SCANAQ, the 36-item questionnaire that aligns agents to individual cognitive styles, and STAC, the spiking-transformer work in its V1 fine-tuning and V2 conversion forms, with hardware validation left as future work.
A correction to this chapter is in progress: a code audit found the STAC V1 spiking pathway inactive as released, and the Appendix B scoring model contained errors. The corrected scoring model is Appendix B 2.0; the full correction record is in the STAC repository.
These figures come from the STAC repository's own test suite and energy projection script (software simulation on DistilGPT-2 and SmolLM2; no neuromorphic hardware has been measured). They replace an earlier estimated comparison chart.
| Quantity | Measured | Meaning |
|---|---|---|
| Conversion fidelity, spiking off | 1.00× perplexity | The converted model reproduces the source model's outputs. |
| Projected energy, spiking on | Worse than the dense model | Operation-count projection at the current spike coverage. Energy is coverage-bound, not sparsity-bound. |
| Frozen model, spiking on | Collapses | Post-hoc conversion needs spike-aware training to recover quality; training recovers it. |
| Hardware energy | Not measured | Intel Loihi 2 validation is planned, not done. |
From healthcare to finance, education to edge computing—SCAN's modular, personalized approach transforms how AI supports human decision-making.
