연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

Functional MRI (fMRI) provides an indirect mapping of cerebral activity, based on the detection of the local blood flow and oxygenation changes following neuronal activity (Blood Oxygenation Level Dependent). fMRI allows us to study noninvasively the normal and pathological aspects of functional cor...

문제 정의

  • 여기에서는 fMRI의 생리적기전, 영상기법, 영상처리 방법 및 실제 응용에 관하여 기술하고자 한다.
  • 제공 할 수 있다. 정상지원자나 환자에서 서로 다른 뇌활성 상태인 활성기와 휴식기의 MR 신호를 비교하는 높은 시간적, 공간적인 분해능에 힘입어 인간의 미지 뇌의 탐구에 있어서 지금까지 사용된 다른 어떤 도구보다 인간의 뇌 기능에 대한 새로운 정보를 제공해 주고 있다. fMRI는 영상기법의 지속적인 발달과 다양한 패러다임의 구현으로 수많은 임상 데이터가 축적되어 가고 있고 그 적용 분야가 널리 확산되어 신경의학의 기초 및 임상 분야에서 큰 역할을 할 것으로 기대된다.

가설 설정

  • B. Functional map activated by hot sensory on the left palm shows activation signals in right primary sensorimotor cortex.
