| Outline of Final Research Achievements |
The results showed that midbrain neurons projecting the medulla, that are excited by exercise, are capable of eliciting locomotor and cardiovascular responses via sympatho-motor activation. Further, these neurons were required for fine regulation of motor coordination and autonomic cardiovascular adjustments during locomotor exercise. The study demonstrated a part of central circuitries for central command.

19世紀末には議論されていた運動時交感神経活性の脳メカニズムは，現在も未解明である．運動発現のために生じる脳活性(セントラルコマンド，CC)は自律神経系も制御すると考えられる．本研究では遺伝子工学を用いた先端技術を融合させたin vivo生理実験から，CCの脳内回路の一端を解明した．本成果は，古典課題「運動時交感神経活性の脳メカニズムの解明」を解決へと導くだけでなく，Exercise is medicineの根幹メカニズムの解明にも資する．
