신장 동 정적인 신경 활동 (방사선학) 및 평균 동맥 압력에 있는 중요 한 매개 변수 심장 혈관과 자율 연구; 그러나, 측정 하 고 이러한 변수를 분석 하기 위한 기술에 있는 과학자를 감독 하는 한정 된 자원 있다. 이 프로토콜에는 방사선학 및 마 취 쥐에 있는 평균 동맥 압력 측정을 위한 방법을 설명 합니다. 프로토콜은 또한 중앙 신경 조직 (CNS) 조작에 대 한 방사선학 녹음 하는 동안 두뇌에 액세스 하는 방법을 포함 한다. 방사선학 녹음 기술 호환 됩니다 pharmacologic, optogenetic, 또는 CNS의 전기 자극. 접근은 조사와 상관 관계를 해부학 CNS 핵 비 생존 실험 단기 (h 분) 자율 반응을 측정할 때 유용 합니다. 접근 쥐에서 방사선학의 만성 (생존) 녹음을 얻기 위해 사용 되는 것이 아닙니다. 방사선학, 평균 방전 방사선학, 정류 및 평균 동맥 압력 수 계량 및 패라메트릭 통계적 테스트를 사용 하 여 추가 분석. 정 맥 접근, telemetrically, 평균 동맥 압력을 기록 하 고 미래 조직학 분석을 위한 뇌 고정을 얻기위한 방법 또한 문서에 설명 되어 있습니다.

그림 1 샘플 방사선학과 혈압 기록을 Nembutal 취 쥐에서 보여 줍니다. 평균 동맥 압력의 증가 유도 하 고 baroreflex 및 과도 sympathoinhibition4,6연상 phenylephrine의 정 맥 주사 사용 되었다. 척도 방사선학, 원시 방사선학 정류 되었고 겹치지 않는 10 s 세그먼트;에 대 한 평균 소음 예측은 각 세그먼트에서 뺍니다.
