Neurotransmitters are chemical messengers that transmit signals across synapses from one neuron to another. They enable all brain function — from basic reflexes to complex thought.
Key Neurotransmitters in ONDA
| Neurotransmitter | Role | ONDA Relevance | |------------------|------|----------------| | Dopamine | Motivation, reward, working memory | Part 8: focus, micro-rewards | | Norepinephrine | Alertness, attention | Part 7–8: cognitive clarity | | Acetylcholine | Attention, learning | Part 8: signal highlighting | | Serotonin | Mood, regulation | Part 1–2: calm, rhythm | | GABA | Inhibition, calm | Part 1–2: parasympathetic |
Depletion and Restoration
Sustained focus depletes neurotransmitters. Ultradian rhythms (90/20-minute cycles) allow timely restoration. Working against these cycles leads to cognitive burnout.
Scientific Basis
Built on: Polyvagal Theory (Porges); Psychoneuroimmunology (Ader & Cohen); neuroplasticity research.
