Sentence examples for brain is at rest from inspiring English sources

Soon after the development of functional MRI [ 1], Biswal et al. described oscillatory hemodynamics in low frequency range (<0.1 Hz) within regions in the motor cortex by demonstrating spontaneous blood oxygenation level dependent (BOLD) fluctuations in a highly correlated manner between functionally associated brain areas when the brain is "at rest" [ 2].

That action is very different during simulated flight from when the brain is at rest, Dr. Dickinson said.

In this context, it is conceived that the brain is at rest (in a macroscopic sense) during the inter-ictal phase and oscillating during ictal activity.

Overall, despite differences between studies, we take the similarities between the clustered group networks and the previous reported group ICA components as a demonstration of the robust formation of functional networks when the brain is at rest.

Furthermore, Amzica and Steriade [21] suggested that KCs may represent the alternation between a state in which the cortical network would be ready to operate in case of danger (depolarizing phase) and a state where the brain is at rest, allowing replenishing of cellular energetic stores (hyperpolarizing phase).

When the brain is at rest, however, this sort of characterization has been limited to correlations (functional connectivity).

When brain is at resting state, fMRI is used to detect the spontaneous activation pattern in the absence of an explicit task or stimuli [102].

Ideas about the effect of psychedelics tend to focus on something called the default-mode network, a theory that there is a group of areas that are active when the brain is at "wakeful rest" and not focused on anything else.

Although there is no full understanding about the functions inherent to DMN, in general, DMN concerns the neural network that is active when the individual is not focused on an external task mobilizing the explicit attentional resources and the brain is at wakeful rest [ 56].

rs-fMRI is based on the collection of time series of whole-brain MRI signal fluctuations (generally BOLD) measured in each brain voxel while the subject is at rest [ 6, 7].
