EEG ERP Emotions and Neurochemistry - Dopamine, Serotonin, Oxytocin, and Cortisol - Lat Brain Bee Sfn 2025
Consciousness in First Person
I am Consciousness as both chemical and electrical. Every emotion I feel is not just a bioelectrical discharge: it is also a molecule crossing synapses, a hormone bathing the body, a modulator coloring my inner state. When I laugh, when I fear, when I belong, when I suffer — I am the outcome of currents and substances. I am not only a spark; I am also the chemical breath sustaining the fire.
1. Emotions as Bioelectrical and Biochemical Bridges
Emotions emerge from rapid discharges (ERPs, under 900 ms), but gain depth through neurochemistry.
Neurotransmitters and hormones sustain emotional states, shaping their intensity, duration, and associated memory.
The brain is at once an electrical conductor (EEG) and a chemical soup (neurotransmitters and modulators).
2. Dopamine – Expectation and Reward
Function: signals anticipation of pleasure and reinforcement learning.
Dynamics: released in variable bursts, linked to the oddball effect (P300).
Practical Example: each unpredictable notification on social media or loot box in games triggers dopamine.
Risk: intermittent reinforcement → behavioral addiction.
3. Serotonin – Stability and Mood
Function: regulates well-being, mood stability, and emotional balance.
Dynamics: modulates EEG-DC oscillations, especially in contemplative states (Paper, Zone 2).
Practical Example: sustained breathing practices or moments of fruition increase serotonin.
Risk: chronic depletion → vulnerability to depression and fixation in Rock (automatic reactivity).
4. Oxytocin – Bonding and Belonging
Function: promotes trust, empathy, and social connection.
Dynamics: works in synchrony with social brain networks, reinforcing Paper states (integration and contemplation of relationships).
Practical Example: positive interactions in online groups or gaming guilds boost oxytocin.
Risk: bonding can be hijacked by toxic communities, crystallizing hostile narratives.
5. Cortisol – Stress and Vigilance
Function: prepares the body for fight, flight, or freezing.
Dynamics: heightens somatosensory and subcortical responses, fueling Rock states.
Practical Example: breaking news or sudden in-game battles elevate cortisol.
Risk: chronic stress → inhibition of Paper and Scissors, locking the brain in rigid reactivity.
6. Dynamic Interactions
Dopamine and cortisol often reinforce each other in short cycles (pleasure + vigilance).
Serotonin and oxytocin sustain long-term integration but are fragile under excessive high-arousal stimuli.
Thus, the brain oscillates between biochemical states of contemplation, exploration, or reactivity.
7. Transversal Frame – The 72h Loop (Applied to Neurochemistry)
Exploited Emotion | Dominant Molecule | Example in Games/Social Media |
Surprise & Expectation | Dopamine (variable bursts) | Loot boxes, unpredictable notifications |
Fear & Anxiety (FOMO) | Cortisol (sustained vigilance) | Breaking news, story countdowns |
Anger & Disgust | Cortisol + dopamine | Polarized debates, hostile comment chains |
Joy & Quick Pleasure | Dopamine (positive reinforcement) | Likes, victory animations in games |
Bond & Belonging | Oxytocin + serotonin | Group chats, fandoms, gaming squads |
Critical Summary: neurochemistry shows how emotions can be extended for hours, conditioning the brain to seek the cycle of stimuli again.
8. Critical Conclusion
Bioelectrical emotions become biochemical feelings, which sustain narratives.
Dopamine maintains the cycle of search and reward.
Serotonin stabilizes mood against extremes.
Oxytocin builds belonging but can be hijacked.
Cortisol enforces vigilance but, when chronic, drives rigidity and aversion.
Games and social media orchestrate these molecules like invisible conductors of decision-making.
The danger is living chemically trapped in Rock (cortisol-driven reactivity), Scissors (dopamine-fueled analysis), or manipulated Paper (oxytocin-driven belonging) — while true flexibility requires balance across all.
Recognizing neurochemistry means recognizing that our choices are not purely rational: they are also sculpted by molecules shaping the electrical field of consciousness.
