Sentence examples for low frequency fluctuation from inspiring English sources
The present study was designed to explore alterations in brain dynamics at rest that are associated with Obsessive Compulsive Symptoms (OCS) in childhood by measuring low frequency fluctuation of spontaneous brain activity in a large school community sample from a developing country.
The BOLD resting state fluctuation is a low frequency fluctuation [14, 15].
In migraine patients Wang and colleagues found altered amplitude of low frequency fluctuation [52], higher and lower amplitudes were found in various parts of the cerebellum.
Furthermore, a few recent studies started to analyse the amplitude of the low frequency fluctuation of the resting state signals [29, 30] offering a unique insight into the resting brain activity in various diseases but not in migraine.
We examined the statistical differences in both functional connectivity and regional amplitude of low frequency fluctuation (ALFF) within the DMN among the 2 4 resting-state conditions (i.e., EC, EO, and EO-F).
The regional activities during rest can be examined by several metrics, such as the root mean square [18], [23], the power spectrum [24], [25], the amplitude of low frequency fluctuation (ALFF) [26], [27], the low-frequency spectral amplitude [28], and the resting state physiological fluctuation amplitude [29].
Turner, J. A. et al. A multi-site resting state fMRI study on the amplitude of low frequency fluctuations in schizophrenia.
A rich and evolving spectrum of intense low frequency fluctuations enable us to make controlled measurements of non-linear particle dynamics, precisely identify the onset of particle chaos, and establish basic principles of plasma transport.
Fractional amplitudes of low frequency fluctuations (fALFF) from rs-fMRI were significantly enhanced at the hyperacute stage in the frequency spectrum between 0.01 and 0.08 Hz.
The electrochemical noise is shown to originate not only from the random birth of edges but also from some low frequency fluctuations of another process.
A multi-site resting state fMRI study on the amplitude of low frequency fluctuations in schizophrenia.
