fMRI를 사용한 연구방법은 뇌의 활동에대한 많은 정보를 과학적으로 제공하는 최신 조영술의 방향을 보여줌으로써 많은 연구결과에서 그 성과들이 임상적 병리학적으로 주요하게 사용되고 있으며 보다 나은 임상 현장과 효과적인 의료적 결정에 도움을 주고 있다.

Hannah Devlin explains how fMRI is used and answers some common criticisms of fMRI. With additional contributions by Stuart Clare and Heidi Johansen-Berg. A Spin Around the Brain. A short animation about fMRI, voiced by Ruby Wax, produced by Oxford Sparks and FMRIB researchers. This book provides a state of the art overview of fMRI and its use in clinical practice, with coverage of new techniques and applications. The book covers technical issues, anatomical landmarks, clinical applications, methods of statistical analysis, and special issues in various clinical fields. What is fMRI?

Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. Functional magnetic resonance imaging, or fMRI, is a technique for measuring brain activity.

Funksjonell MR-undersøkelse, fMRI, er en bildediagnostisk teknikk som måler og dokumenterer hvordan metabolismen varierer i ulike områder av hjernen. Økt metabolisme er en konsekvens av økt hjerneaktivitet og viser seg som lysende områder med økte signaler på fMRI.

There is a wide range of functional magnetic resonance imaging (fMRI) study designs available for the neuroscientist who wants to investigate cognition. In this manuscript we review some aspects of fMRI study design, including cognitive comparison strategies (factorial, parametric designs), and stim …
