BRS1 — Neurotransmitter Regulation

BRS1(FM1) - Monoaminergic Function​

1. Definition​

Functional regulation of dopamine, noradrenaline and serotonin signalling, supporting attention, motivation, arousal, emotional regulation, reward processing and behavioural control.

2. Functional Outcome Context​

These outcomes describe translational contexts for the FM as an integrated biological capacity. They are not single-mechanism treatment claims. Confidence may increase where multiple child PMs converge on the same functional outcome.

No functional outcome context currently mapped.

3. Functional Role​

↑ precursor availability; ↑ tyrosine/tryptophan support; improved monoaminergic brain-delivery context

4. Mechanistic Basis (Integrated FM Narrative)​

Monoaminergic function emerges from the coordinated interaction of several primary mechanisms and supporting biological pools.

4.1 Core Primary Mechanisms​

4.2 Integrated Functional Narrative​

Together, these PMs operationalise BRS1(FM1) as coordinated meal-level control of monoaminergic and related neurotransmitter signalling.

4.3 Functional Failure Modes​

Monoaminergic function may weaken when amino acid quality & competitive balance declines or when reliance on incomplete protein sources without complementary pairing.

Reliance on incomplete protein sources without complementary pairing may reduce BRS1(KC2) — Amino Acid Quality & Competitive Balance. Chronically low indispensable amino-acid coverage across meals may further strain pool availability, lNAA imbalance favouring transport competition away from key precursors, ultra-processed low-protein dietary patterns, while inconsistent protein distribution across the day.

These pressures may impair BRS1-FM1-PM1 — Amino-Acid Availability & Prioritisation, weaken BRS1-FM2-PM4 — LAT1 Competitive Transport Modulation, and reduce the effectiveness of BRS1-FM1-PM2 — Noradrenergic Signalling (Attention & Executive Modulation). At the FM level, this may shift BRS1(FM1) toward reduced monoaminergic function performance.
