Topic_Agent/Topic_Blog/Topics/Topics_Biz/Topics_Meeting/Topics_Rag의 마크다운 지식 문서를 Topic_General/Topic_Programming/Topic_Graphic/Topic_Business 4개 카테고리로 재분류. - 중복 제거: frontmatter의 status:duplicate/merged + duplicate_of/redirect_to 필드로 자기 자신을 중복으로 선언한 리다이렉트 stub 1032개 제거, 완전 동일 내용 파일 472개 제거, 동일 파일명·다른 내용 충돌 시 더 큰(완전한) 버전만 유지(162개 제거) — 총 1639개 중복 제거. - 분류: 폴더 단위로 명확한 항목(AI_and_ML/Coding/Architecture 등 → Programming, Comfyui/Visual_Effects → Graphic, Topics_Biz/Topics_Meeting/사업 등 → Business, Poetic_Blog_Writing/창의성/Game_Design 등 → General)은 폴더 우선순위로, 나머지 혼재 폴더(Topic_Agent/Topic_Blog/Topics 루트/Thinking & Reasoning/Other/UI_UX_Assets)는 title/tags 키워드 스코어링으로 파일 단위 분류(불명확한 경우 General로 폴백). 원본 폴더명은 "From_*" 서브폴더로 보존해 추적 가능성 유지. - 최종 배치: Programming 2784 / General 1608 / Graphic 285 / Business 249 = 4926개 문서. - 에이전트 운영 상태(.astra/.agent/.obsidian/sessions/memory/_company/docs/lessons/_shared/src)는 지식 콘텐츠가 아니므로 재분류 대상에서 제외하고 원위치 유지. - Topics/Topic_email(상위 보호 폴더 Topic_email과 파일명 100% 중복) 삭제 — 보호 폴더 자체는 미변경. - 완전히 비게 된 Topic_Agent/Topic_Blog/Topics_Biz/Topics_Rag 폴더 제거.

Amygdala Hyperactivity
매 한 줄
"매 amygdala 의 exaggerated response 의 threat / emotional stimuli — 매 anxiety, PTSD, depression 의 transdiagnostic biomarker." 매 fMRI BOLD response 의 elevation (특히 face/threat tasks) — 매 prefrontal regulation 의 hypoactivity 와 pair — 매 2026 에 SSRI, CBT, TMS, psychedelic-assisted therapy 의 normalization target.
매 핵심
매 circuit
- Amygdala: 매 basolateral (BLA, threat learning) + central (CeA, autonomic output).
- vmPFC / dlPFC: 매 top-down inhibition — 매 hyperactivity 와 anti-correlation.
- HPA axis: 매 amygdala → CRH → cortisol — 매 chronic activation 의 maladaptive.
매 conditions
- Anxiety disorders: GAD, social anxiety, panic.
- PTSD: 매 trauma-associated cue 의 sensitization.
- MDD: 매 sad-face bias.
- BPD: 매 emotional reactivity.
- Autism: 매 mixed — face-processing 의 atypical activation.
매 응용
- Diagnostic biomarker (research stage).
- Treatment response prediction (SSRI, exposure therapy).
- Neurofeedback / TMS target localization.
💻 패턴
fMRI BOLD extraction
from nilearn import image, masking, datasets
# Load Harvard-Oxford amygdala mask
atlas = datasets.fetch_atlas_harvard_oxford('sub-maxprob-thr25-2mm')
amyg_mask = image.math_img("img == 10", img=atlas.maps) # left amyg label
# Extract task BOLD
bold = image.load_img("sub-01_task-faces_bold.nii.gz")
amyg_ts = masking.apply_mask(bold, amyg_mask).mean(axis=1)
Threat > neutral contrast
from nilearn.glm.first_level import FirstLevelModel
events = pd.DataFrame({
"onset": [0, 20, 40, 60],
"duration": [10]*4,
"trial_type": ["threat", "neutral", "threat", "neutral"],
})
flm = FirstLevelModel(t_r=2.0, hrf_model="spm")
flm.fit(bold, events=events)
contrast = flm.compute_contrast("threat - neutral", output_type="z_score")
Functional connectivity (amyg-vmPFC)
from nilearn.connectome import ConnectivityMeasure
# Time series from amyg + vmPFC ROIs
ts = np.column_stack([amyg_ts, vmpfc_ts])
conn = ConnectivityMeasure(kind="correlation")
fc = conn.fit_transform([ts])[0] # 2x2 corr matrix
amyg_vmpfc_fc = fc[0, 1] # negative in healthy, weaker in anxiety
HRV proxy (peripheral readout)
import neurokit2 as nk
ecg = nk.ecg_clean(ecg_signal, sampling_rate=500)
peaks = nk.ecg_peaks(ecg, sampling_rate=500)[0]
hrv = nk.hrv_time(peaks, sampling_rate=500)
# Low RMSSD ↔ high sympathetic ↔ amyg overdrive
Real-time fMRI neurofeedback target
def neurofeedback_signal(current_volume, amyg_mask, baseline_mean, baseline_std):
activation = masking.apply_mask(current_volume, amyg_mask).mean()
z = (activation - baseline_mean) / baseline_std
# Display inverted bar — patient learns to downregulate
return -z
매 결정 기준
| 상황 | Intervention |
|---|---|
| Acute anxiety | Benzodiazepine (short-term), breathing |
| Chronic anxiety | SSRI/SNRI + CBT |
| PTSD | Trauma-focused CBT, EMDR, prazosin (nightmares) |
| Treatment-resistant | TMS (dlPFC), ketamine, psilocybin trials |
| Research / monitoring | fMRI + HRV biomarkers |
기본값: 매 CBT + SSRI — 매 6-12 weeks 의 expected normalization.
🔗 Graph
- Adjacent: Autism-Spectrum-Disorder
🤖 LLM 활용
언제: 매 patient psychoeducation, 매 literature summarization. 언제 X: 매 diagnosis, 매 treatment prescription — 매 clinician 의 only.
❌ 안티패턴
- Single-region focus: 매 amygdala alone — 매 circuit (vmPFC, hippocampus) 의 consideration.
- State vs trait conflation: 매 task-induced state ≠ stable trait.
- Reverse inference: 매 amyg activation = "fear" — 매 many functions.
- fMRI as diagnostic: 매 group-level 의 individual 의 X.
🧪 검증 / 중복
- Verified (Etkin & Wager 2007 meta-analysis, Shin & Liberzon 2010, Stein et al. 2007).
- 신뢰도 A.
