Explore the core frameworks, parent resources, research materials, and educational tools that organize this work.
For Parents
This path helps parents separate autism traits from comorbid traits so support can be matched to the right problem. It explains how skills and behaviors are supported through neural circuits and neuroplasticity, how body-based comorbid traits relate to regulatory systems, and where to start with nonverbal autism, communication, and advocacy.
For Researchers
This path provides access to the research papers, timeline, primary sources, methodology, framework structure, validation, and credentials needed to evaluate the model. It is organized to support review of the framework’s construction, biological structure, and comparison to independent findings.
For Educators
This path explains how learning, memory, skills, and behavior are encoded in neural circuits, how neurodevelopmental differences alter that process, and how instruction can be aligned to those differences to build and strengthen skills through neuroplasticity using the NeuroToggle framework.
For Neurodivergent Individuals
This path explains the pathology of autism and comorbid traits, including the biological mechanisms that cause them to cluster. It uses the five core frameworks to map how regulatory systems, biochemical pathways, and developmental timing interact across the body and brain.
From Silence to Speech
Kimberly Kitzerow, founder of Kimberly's Educational Resources, is a mother and educator who helped her nonverbal autistic daughter speak, and created a novel framework for understanding neurodivergence.
- Autism Traits: NeuroToggle® for skill and behavior development
- Comorbid Traits: Neurodivergent Biochemistry for understanding how stress alters development and function over time
- Educational frameworks and instructional strategies
- Systems-level models of neurodevelopment and physiology
- Resources for educators, parents, researchers, and autistics
From one child’s progress to five frameworks
Watch how this work developed from real-world application into NeuroToggle® and Neurodivergent Biochemistry.
Neurodivergence changes how neural circuitry forms.
If the circuitry isn’t built, skills and behaviors won’t show up.
NeuroToggle® shows how to build, strengthen, time, and expand the neural pathways that produce skills and behaviors so development can actually occur.
NeuroToggle® Foundations
Reframes education through neuroplasticity and explains why behavior-only approaches are limited when the circuitry behind skill performance is not being built directly.
Start with Book 1The NeuroToggle® Framework
Formalizes NeuroToggle® into a neuroscience-based instructional framework built around building, strengthening, timing, and expanding neural connections.
Continue with Book 2Autism and Comorbid Traits
Autism traits and comorbid traits arise from the same underlying processes, but affect different systems in the body. Because of that, they do not respond to the same type of support.
Educational Consulting
NeuroToggle®
- The information for how to “do” skills and behaviors is encoded in neural circuits.
- Neurodevelopmental conditions impact how those circuits form, which impacts skill and behavior development.
- Neuroplasticity targets how those circuits are built and refined.
- NeuroToggle® uses established teaching pedagogy to optimize the building, strengthening, timing, and expansion of neural circuits.
Research and Advocacy
Neurodivergent Biochemistry
- Neurodivergent Biochemistry studies how different categories and durations of stress activation alter development and function over time.
- BioToggles define the categories of stress activation.
- BioDials define the typical development and function cycles that are disrupted.
- Kitzerow’s Autism and the Comorbidities Theoretical Model defines long-term developmental and functional outcomes.
The Breakthrough and Validation
What began as Kimberly Kitzerow's effort to help her daughter speak led to the development of NeuroToggle® and the broader frameworks that followed.
-
2020 - The Problem
Kimberly’s daughter was nonverbal and unable to coordinate the motor patterns required for speech.
-
2020 - The Shift
When she could not blow out the candles on her fourth birthday cake, it revealed that the neural circuits required for coordinated speech were not functioning as intended.
-
2021 - Building NeuroToggle®
Neuroplasticity was applied to build, strengthen, time, and expand those circuits into communication. This is the foundation of NeuroToggle®.
-
2022 - The Results
Her daughter became conversational, and she began sharing their story online in the hopes of helping more children.
-
2023 – Theoretical Model
Developed the Autism and Comorbidities Model, formed Kimberly’s Educational Resources LLC, and began writing.
-
2024 – Framework Expansion
Developed Neurodivergent Biochemistry and documented the work through resources, websites, videos, and ResearchGate articles.
-
2024 – Education + Funding
Crowdfunded for Bioinformatics at UW–Madison, earned all A’s, requested support, and was told a PhD was required before assistance.
-
2025–2026 – Validation
Within months, independent research aligned with and validated the core pillars of this model at the mechanistic level.
