Characterization of cardiac- and respiratory-driven cerebrospinal fluid motion based on asynchronous phase-contrast magnetic resonance imaging in volunteers

Fluids and Barriers of the CNS, 2017
Background A classification of cardiac- and respiratory-driven components of cerebrospinal fluid (CSF) motion has been demonstrated using echo planar imaging and time-spatial labeling inversion pulse techniques of magnetic resonance imaging (MRI ...

Circuit formation and sensory perception in the mouse olfactory system

Frontiers in Neural Circuits
In the mouse olfactory system, odor information is converted to a topographic map of activated glomeruli in the olfactory bulb (OB). Although the arrangement of glomeruli is genetically determined, the glomerular structure is plastic and can be modified ...

Cycle-by-cycle assembly of respiratory network activity is dynamic and stochastic

Journal of Neurophysiology, 2013
Rhythmically active networks are typically composed of neurons that can be classified as silent, tonic spiking, or rhythmic bursting based on their intrinsic activity patterns. Within these networks, neurons are thought to discharge in distinct phase relationships with their overall network output, and it has been hypothesized that bursting pacemaker ...

Hippocampal sharp-wave ripples in awake mice are entrained by respiration

Scientific Reports, 2017
Several recent studies have shown that respiration modulates oscillatory neuronal activity in the neocortex and hippocampus on a cycle-by-cycle basis.

Elevated TCA cycle function in the pathology of diet-induced hepatic insulin resistance and fatty liver[S]

Journal of Lipid Research, 2012
The manner in which insulin resistance impinges on hepatic mitochondrial function is complex. Although liver insulin resistance is associated with respiratory dysfunction, the effect on fat oxidation remains controversial, and biosynthetic pathways that ...
