Brain-Derived Neurotrophic Factor (BDNF)

📌 한 줄 통찰

"매 brain 의 fertilizer". 매 protein 의 synapse plasticity + 매 neurogenesis 의 boost. 매 exercise / sleep / fasting / novelty 의 강력 의 인상. 매 cognitive worker (developer, researcher) 의 daily routine 의 design 의 leverage. 매 cortisol 의 antagonist.

📖 핵심

매 정의

• 매 neurotrophin family 의 protein.
• 매 hippocampus, cortex 의 high.
• 매 TrkB receptor binding.
• 매 neuronal survival + 매 plasticity.

매 function

1. Neurogenesis: 매 new neuron (hippocampus).
2. Synaptic plasticity: 매 LTP (Long-Term Potentiation).
3. Memory formation: 매 hippocampus-dependent.
4. Mood: 매 depression 의 antidote.
5. Cognitive reserve: 매 dementia 의 buffer.

매 boost factor

Exercise (매 strongest)

• 매 lactate (irisin) 의 mediation.
• 매 chronic 의 best.

• 매 deep sleep 의 BDNF expression.
• 매 7-9 hour.
• 매 sleep deprivation 의 BDNF ↓.

Fasting / caloric restriction

• 매 BDNF ↑ (intermittent).
• 매 ketone body 의 mediator.

Novelty / learning

• 매 new task 의 BDNF release.
• 매 enrichment.

Sunlight / cold

• 매 mild stress 의 hormesis.

Diet

• Curcumin (turmeric).
• Omega-3 (fish, flaxseed).

• NSI-189: 매 phase 2 antidepressant.
• 7,8-DHF: 매 TrkB agonist.

• Psychedelics (psilocybin): 매 plasticity surge.

매 suppressor

• Cortisol (chronic stress).
• Sleep deprivation.
• Sedentary lifestyle.
• High sugar diet.
• Inflammation (IL-6).
• Social isolation.

매 응용 (cognitive worker)

1. Morning exercise: 매 brain prep.
2. Walk break: 매 every 90 min.
3. Sleep hygiene: 매 fixed schedule.
4. Intermittent fasting (16:8): 매 cognitive boost.
5. Skill practice: 매 deliberate practice.
6. Stress management: 매 cortisol ↓.
7. Social connection: 매 isolation 의 avoid.

매 measurement

• Serum BDNF (blood test): 매 noisy.
• Plasma BDNF: 매 better.
• CSF BDNF: 매 invasive.
• → 매 individual 의 sensitive 가, 매 daily 의 actionable X.

매 modern research direction

• BDNF-TrkB drug: 매 depression / Alzheimer.
• Exercise pill: 매 myokine + irisin.
• Targeted plasticity (psychedelic-assisted therapy).

🤔 결정 기준

상황	Action
Stuck on problem	Walk 15 min
Pre-deep-work	Aerobic exercise
Post-learning	Sleep 8h
Chronic stress	Reduce stressor + exercise
Brain fog	Fasting + walk
Creative block	Novelty (new place / skill)
Aging brain	Exercise + social + learn

기본값: 매 daily exercise 30 min + 매 sleep 8h + 매 omega-3 + 매 stress mgmt.
