Cerebellum Timing & coordination Repetitive motor patterns, difficulty pacing ASD, ADHD, FASD, Trauma
1. Prefrontal Cortex (The Thought Regulator & Cognitive Control Center)

Role:

    • Governs flexible thinking, impulse control, and stopping repetitive thoughts
    • Helps shift focus from one idea to another

Common Challenges
When Underdeveloped: Getting “stuck” on thoughts, repeating the same idea or action, difficulty stopping repetitive speech or behaviors

Most Impacted in: ASD, ADHD, FASD, Trauma

2. Anterior Cingulate Cortex (The Cognitive Shift & Attention Manager)

Role:

    • Helps with task-switching and adjusting to new information
    • Regulates internal error detection and correction

Common Challenges
When Underdeveloped: Struggling to shift focus, getting stuck on routines, repeating mistakes

Most Impacted in: ASD, ADHD, FASD, Trauma

3. Basal Ganglia (The Habit & Repetition Control System)

Role:

    • Helps regulate automatic behaviors and movement patterns
    • Supports switching between motor tasks and cognitive tasks

Common Challenges
When Underdeveloped: Repeating words or actions, struggling to “break” habits, difficulty with new routines

Most Impacted in: ASD, ADHD, FASD

4. Orbitofrontal Cortex (The Social & Emotional Response Adjuster)

Role:

    • Helps regulate behavioral flexibility and social appropriateness
    • Adjusts responses based on context and past experiences

Common Challenges
When Underdeveloped: Repetitive social missteps, getting fixated on past mistakes, difficulty adapting to new information

Most Impacted in: ASD, ADHD, FASD, Trauma

4. Orbitofrontal Cortex (The Social & Emotional Response Adjuster)

Role:

    • Helps regulate behavioral flexibility and social appropriateness
    • Adjusts responses based on context and past experiences

Common Challenges
When Underdeveloped: Repetitive social missteps, getting fixated on past mistakes, difficulty adapting to new information

Most Impacted in: ASD, ADHD, FASD, Trauma

5. Amygdala (The Emotional Memory & Response System)

Role:

    • Regulates emotional intensity in perseverative thoughts
    • Helps with emotional transitions and learning from past experiences

Common Challenges
When Underdeveloped: Emotional perseveration (repeating anxious thoughts, dwelling on fears, re-experiencing trauma-related distress)

Most Impacted in: ASD, ADHD, FASD, Trauma

6. Hippocampus (The Memory & Learning Integration System)

Role:

    • Stores past experiences to guide new learning and problem-solving
    • Helps differentiate between past and present concerns

Common Challenges
When Underdeveloped: Repeating questions, reliving past negative experiences, struggling to integrate new learning

Most Impacted in: FASD, Trauma, ASD

7. Insula (The Self-Awareness & Sensory Processing Hub)

Role:

    • Helps regulate awareness of internal emotions and body sensations
    • Supports recognition of changes in the environment

Common Challenges
When Underdeveloped: Getting fixated on sensory experiences, repeating self-soothing behaviors, struggling to recognize internal stress signals

Most Impacted in: ASD, ADHD, FASD, Trauma

8. Dorsolateral Prefrontal Cortex (The Thought-Filtering System)

Role:

    • Helps organize and manage intrusive thoughts
    • Supports stopping unwanted or repetitive thinking patterns

Common Challenges
When Underdeveloped: Intrusive thoughts, repetitive concerns, trouble letting go of an idea or worry

Most Impacted in: ASD, ADHD, FASD, Trauma

9. Parietal Cortex (The Cognitive Awareness & Shift Center)

Role:

    • Supports attention control and shifting between cognitive tasks
    • Helps understand and adjust to changes in surroundings

Common Challenges
When Underdeveloped: Difficulty shifting attention, hyper-focusing on one topic, struggling to transition between activities

Most Impacted in: ASD, ADHD, FASD

10. Cerebellum (The Motor & Cognitive Timing Coordinator)

Role:

    • Regulates timing of movements and thoughts
    • Helps maintain rhythmic transitions between tasks

Common Challenges
When Underdeveloped: Getting “stuck” in repetitive motion patterns, difficulty pacing actions or thoughts

Most Impacted in: ASD, ADHD, FASD, Trauma

11. Broca’s Area (The Speech & Language Output Regulator)

Role:

    • Governs speech production and verbal expression
    • Helps regulate rhythm, fluency, and appropriateness of speech

Common Challenges
When Dysregulated: Verbal perseveration (repeating phrases, echolalia, difficulty stopping speech loops)

Most Impacted in: ASD, ADHD, FASD, Trauma

12. Wernicke’s Area (The Language Comprehension & Processing Center)

Role:

    • Responsible for understanding spoken language
    • Helps process meaning, context, and nuance in speech

Common Challenges
When Dysregulated: Misinterpretation of conversations, repeating misunderstood phrases, difficulty shifting topics appropriately

Most Impacted in: ASD, FASD, Trauma

13. Sensory Cortices (The Sensory Processing & Filtering Hub)

Role:

    • Processes sensory input from the environment (touch, sound, sight, etc.)
    • Helps filter and integrate sensory information to guide appropriate responses

Common Challenges
When Dysregulated: Getting “stuck” on sensory input (e.g., repetitive touching, fixating on a sound, visual perseveration like staring at lights)

Most Impacted in: ASD, ADHD, FASD

14. Thalamus (The Sensory Relay & Attention Modulator)

Role:

    • Acts as a relay station for sensory and motor signals
    • Regulates attention, focus, and cognitive switching between tasks

Common Challenges
When Dysregulated: Difficulty shifting attention from one task to another, sensory hyper-fixation, trouble disengaging from thoughts

Most Impacted in: ASD, ADHD, FASD, Trauma

15. Frontal Eye Fields (The Visual Attention & Tracking System)

Role:

    • Controls eye movements that support attention shifting
    • Helps track changes in the environment and shift focus between tasks

Common Challenges
When Dysregulated: Fixation on objects or scenes, difficulty shifting visual attention, repetitive eye movements or staring behaviors

Most Impacted in: ASD, ADHD, FASD
