BRS1 — Neurotransmitter Regulation

BRS1(SM-PHEN1) - Excitatory–Inhibitory Stability & Sensory Regulation​

1. Definition​

Interpretive overlay for individuals experiencing sensory overwhelm, reactivity, or difficulty maintaining inhibitory control when excitatory–inhibitory balance is under strain. This SM frames how connected BRS1 mechanisms may support regulatory stability at the meal and pattern level — not as a diagnostic label or deterministic phenotype outcome.

2. Intervention Breakdown​

Food-State Leaning

3. Functional Role​

↑ E/I regulatory stability context; ↑ sensory-load resilience support; ↓ destabilisation from arousal–glycaemic coupling

4. Mechanistic Basis​

Summary​

BRS1(SM-PHEN1) applies BRS1(FM5) and its PM cluster (BRS1(PM6)–BRS1(PM9)) to phenotype-level interpretation: when glutamatergic drive and GABAergic tone are poorly matched, attention, reactivity, and sensory filtering may feel less stable. Dietary patterns that support inhibitory tone, glutamate handling, and cofactor sufficiency provide context for resilience — without replacing clinical assessment.

E/I balance, sensory load, and connected PM biology

(Network balance as interpretive frame)​

Excitatory–inhibitory balance is a network property, not a single nutrient effect. Shifts in GABAergic versus glutamatergic signalling have been associated with variability in inhibitory control profiles relevant to attention-related contexts → Edden et al. (2012) [1]

(PM cluster — stable biology, phenotype application)​

BRS1(PM6) integrates meal-level protein, magnesium, zinc, and B6 context with BRS1(PM7) and BRS1(PM8). BRS1(PM9) adds excitotoxicity-modulation context. This SM does not redefine those PMs; it orients their combined logic toward sensory regulation and destabilisation reduction → Puts et al. (2020) [2]

(Cross-BRS and substrate context)​

BRS1(KC1) supplies general amino-acid substrate context. Glycaemic and stress load (BRS6 links on connected PMs) may indirectly affect arousal; primary framing here remains E/I stability.

5. Underlying Mechanisms and Requirements​

5.1 Co-factors​

  • B6, magnesium, zinc

5.2 KCs (Key Constraints)​

5.3 Connected Primary Mechanisms (PMs)​

5.4 Connected Functional Mechanisms (FMs)​

  • BRS6 — Glycaemic stability and stress-recovery context

6. Dietary Levers​

Diet

  • Magnesium ← leafy greens, pumpkin seeds

  • Zinc ← pumpkin seeds, legumes

  • B6 ← lentils, poultry, fish

  • Tyrosine ← poultry, eggs, dairy

  • Tryptophan ← poultry, eggs, dairy

  • Protein-rich meals with meaningful amino-acid completeness may support substrate and cofactor context for the connected E/I PM cluster (BRS1(PM6)).

  • Slow, mixed-macronutrient meals where glycaemic volatility may worsen reactivity may indirectly affect stability via BRS6 coupling (meal-pattern lever).

7. Lifestyle Levers​

Lifestyle
  • Sensory-load management and recovery windows may reduce concurrent stress on inhibitory control systems.
  • Circadian-aligned meal timing may support precursor transport context where timing materially alters meal effects.
  • Sleep and stress-recovery practices may modulate autonomic arousal that interacts with E/I balance interpretation.

8. Scoreable Inputs & Modulation Signals​

This SM is scoreable through food-state signals that support the connected E/I PM cluster.
