EEG ERP Metacognition, Critique, and Narrative Rewriting (25–35 Years) - FALAN SfN 2025 Brain Bee Ideas
Consciousness in First Person
I am Consciousness in maturation. Before, I was carried away by emotions and desires like a current without control. Now, between ages 25 and 35, I discover that I can pause, reflect, and ask myself: “Why do I feel this? Why do I choose this way?” I am metacognition — the capacity to think about my own thinking, to rewrite my own narratives. I am not yet total certainty, but I am no longer dragged; I begin to steer.
1. What is Metacognition?
The ability to observe and evaluate one’s own thoughts, feelings, and actions.
Develops gradually, reaching maturity between ages 25 and 35, when the prefrontal cortex becomes fully consolidated.
Enables recognition of when we are being driven by quick emotions and allows more critical, conscious responses.
2. The Role of Top-Down Maturation
Cortical maturation follows a bottom-up, back-to-front trajectory.
Before 25: predominance of fast emotional reactions (amygdala + ERP).
Between 25–35: strengthening of prefrontal regulation, enabling review of memories and narratives.
This opens space for internal questioning, not just reaction.
3. Emotions as Gateways to Feelings
Bioelectrical emotions are brief but generate feelings when metabolized.
Risk: if crystallized without critique, they may turn into rigid “local optima”, aversive memories, or Anergia (when the brain cannot transform emotion into healthy expression).
Opportunity: metacognition allows us to feel all emotions without being trapped in one, building flexible narratives.
4. Rewriting Narratives
Through metacognition, memories can be revisited and reinterpreted.
This does not erase the past but transforms the meaning attributed to events.
Example: a school failure seen as “inability” during adolescence may later be reframed as “learning” in adulthood.
This rewriting depends on Zone 2, which sustains contemplative and critical states.
5. Neuroscience of Metacognition
EEG-DC and microstates: show greater prefrontal stability during reflective states.
Ca²⁺ ion flows and neural synchrony: support reorganization of networks between prefrontal cortex, hippocampus, and insula.
Neurochemistry: serotonin and oxytocin sustain stability, while dopamine provides motivation for narrative reorganization.
6. Comparative Frame – Before and After Metacognition
Age Range | Dominant Dynamic | Risk | Critical Potential |
Up to 25 years | Fast emotions + fragile narratives | Identities hijacked by algorithms | Spontaneous creativity |
25–35 years | Prefrontal maturation + metacognition | Rigidity if critique is absent | Ability to rewrite narratives |
After 35 years | Stable narratives | Anergia or fixation in aversive ones | Critical stability and security |
7. Critical Conclusion
Between 25 and 35, the brain experiences a unique window:
No longer fully dragged by fast emotions.
Not yet crystallized into full rigidity.
At the peak of metacognition, able to review and rewrite narratives.
This is also when responsibility increases — regarding information, emotions, and psychoactive use.
If cultivated in Zone 2, metacognition creates the ground for a critical, flexible consciousness capable of resisting imposed narratives.
Rewriting personal stories is not denying who we were, but choosing who we want to become.
