Abstract (English)

Adaptive Neuroplasticity Theory (ANeT) is a neuro-scientific framework proposed by Junichiro Kojou (Institute for Neuroscience, Japan) that explains how neural circuits reorganize toward functional optimization under clinical intervention, environmental change, and human performance demands. ANeT builds upon biological homeostasis and neural plasticity, and models adaptive reorganization as an interaction among sensory input, motor output, and neural transmission dynamics. The framework is intended to generate testable predictions and practical protocols across clinical rehabilitation, sports science, and human performance medicine.

要旨(日本語)

ANeT理論(神経適応可塑性理論)は、神経医科学研究所 小城絢一朗博士により提唱された神経科学的フレームワークであり、 臨床介入、環境変化、身体・認知パフォーマンスの要求に応じて、神経ネットワークが 機能的に再編成・最適化される過程を説明する。 ANeT理論はホメオスタシス(恒常性)と神経可塑性を基盤に据えつつ、感覚入力―運動出力―神経伝達ダイナミクスの相互作用によって 適応が進むというモデルを提示し、リハビリテーション、スポーツ科学、ヒューマンパフォーマンス領域で 検証可能な予測と実装指針を提供する。

Official Definition

Definition (EN):
Adaptive Neuroplasticity Theory (ANeT) defines functional optimization as adaptive reorganization of neural networks driven by structured interactions among sensory inputs, motor outputs, and neural transmission dynamics, under constraints of biological homeostasis, and modulated by clinical or performance-oriented interventions.

定義(JP):
ANeT理論は、ホメオスタシス(恒常性)の制約条件のもとで、感覚入力・運動出力・神経伝達ダイナミクスの相互作用が 構造化された介入により変調され、神経ネットワークが適応的に再編成されることで機能が最適化される、という過程を定義する。

Scope & Boundary Conditions

Scope (What ANeT explains)

  • 短期〜中期の機能変化(痛み・可動域・動作・疲労・認知など)に伴う神経ネットワーク再編
  • 感覚入力と運動出力の再重み付け(re-weighting)による運動制御・認知制御の改善
  • 臨床介入・トレーニング介入による適応(adaptive gain / gating / coupling)

Non-scope (What ANeT does NOT claim)

  • すべての慢性疾患の原因を説明する“万能理論”ではない
  • 分子生物学的メカニズムの全解明を本ページで完結させるものではない
  • 単なる「元に戻す(回復)」だけでなく「機能最適化」も扱うが、無制限な向上を保証する理論ではない

Core Mechanism (Conceptual Model)

ANeT models adaptive reorganization as a loop: Sensory Input → Neural Transmission Modulation → Network Reweighting/Rewiring → Motor/Cognitive Output → Feedback. Biological homeostasis acts as a constraint, while intervention can shift thresholds, gains, and coupling across networks.

Intervention Categories (Implementation)

  • Receptor-level input modulation: structured adjustment of sensory/receptor input.
  • Motor output relearning: recalibration and relearning of motor outputs.
  • Max ROM shift: measurable changes in maximal range of motion as a functional boundary update.
  • Autonomic state regulation: adjustment of autonomic state as a precondition for adaptive reorganization.

介入の分類(実装)

  • 受容器への入力調整(感覚入力の構造化)
  • 運動出力の再学習(出力の再較正・再学習)
  • 最大可動域(Max ROM)の変化(機能境界の更新として評価)
  • 自律神経の状態調整(適応再編の前提条件としての状態制御)

Homeostasis in ANeT

Positioning: In ANeT, homeostasis is treated as a foundational constraint, not the ultimate goal. The system may return to stability, but ANeT emphasizes how structured interventions can drive the network toward a new, higher-order functional state (functional optimization) while remaining physiologically viable.

位置づけ(日本語): ANeT理論では、ホメオスタシス(恒常性)を基盤となる制約条件として扱い、到達目標そのものには置かない。 安定化(回帰)だけでなく、介入によって新たな高次機能状態へと移行する「機能最適化」を重視する。

Testable Predictions (Examples)

  1. Intervention-specific signatures: A structured intervention yields measurable, repeatable changes in objective markers (e.g., HRV indices) beyond spontaneous fluctuation.
  2. Network reweighting: Improvement correlates with changes in sensory-motor coupling measures rather than symptom relief alone.
  3. State dependence: Outcomes depend on baseline neural/autonomic state, predicting heterogeneous responses explainable by stratification.

Operational Definitions & Measurements

  • Functional optimization: improvement in objective performance and/or clinically meaningful function under standardized tasks.
  • Adaptive reorganization: consistent changes in task performance patterns plus associated physiological/behavioral markers after intervention.

Objective Measurement Indicators (Institute Standards)

  • Pulse wave / ECG / Pulse rate-based HRV: LF, HF, TP are calculated from pulse wave, electrocardiogram, and pulse rate signals.
  • Autonomic indices: Sympathetic activity, parasympathetic activity, and overall neural function are assessed using HRV-derived metrics.

指標(研究所で用いる客観指標)

  • 脈波・心電波・脈拍からHRV指標としてLF, HF, TPを計測する。
  • 自律神経指標:HRV由来指標により、交感神経副交感神経神経機能全体の働きを評価する。

Applications

  • Clinical rehabilitation and neuro-functional recovery
  • Sports science and performance optimization
  • Neuro-cognitive training and behavioral adaptation
  • Human-environment interaction and adaptive health systems
