Rat brains also have a default mode network
The default mode network (DMN) in humans has been suggested to support a variety of cognitive functions and has been implicated in an array of neuropsychological disorders. However, its function(s)Expand

Characterization of continuously distributed cortical water diffusion rates with a stretched‐exponential model
Experience with diffusion‐weighted imaging (DWI) shows that signal attenuation is consistent with a multicompartmental theory of water diffusion in the brain. The source of this so‐calledExpand

Frequency specificity of functional connectivity in brain networks
Synchronized low-frequency spontaneous fluctuations of the functional MRI signal have been shown to be associated with electroencephalography (EEG) power fluctuations in multiple brain networks within predefined frequency bands. Expand

Spatial correlations of laminar BOLD and CBV responses to rat whisker stimulation with neuronal activity localized by Fos expression
The spatial relationship between a measured fMRI signal and its underlying neuronal activity remains unclear. One obstacle is the localization of neuronal activity; another is the spatial resolutionExpand

Resting-State Functional Connectivity in Rat Brain
Introduction Synchronized low-frequency fluctuations in resting-state fMRI (1) have been used to investigate functional connectivity between brain areas. Recent studies demonstrate that thisExpand

Cocaine-induced brain activation detected by dynamic manganese-enhanced magnetic resonance imaging (MEMRI)
Dynamic manganese-enhanced magnetic resonance imaging (MEMRI) detects neuronal activity based on the passage of Mn2+ into active neurons. Because this mechanism is independent of any hemodynamicExpand

Mapping functional connectivity based on synchronized CMRO2 fluctuations during the resting state
Synchronized low-frequency fluctuations in the resting state functional MRI (fMRI) signal have been suggested to be associated with functional connectivity in brain networks. Expand

Large-Scale Brain Networks in the Awake, Truly Resting Marmoset Monkey
Resting-state functional MRI is a powerful tool that is increasingly used as a noninvasive method for investigating whole-brain circuitry and holds great potential as a possible diagnostic forExpand

Quantifying the blood oxygenation level dependent effect in cerebral blood volume–weighted functional MRI at 9.4T
In cerebral blood volume (CBV)‐weighted functional MRI (fMRI) employing superparamagnetic contrast agent, iron dose and blood oxygenation level dependent (BOLD) contamination are two important issuesExpand
