To determine the relationship between functional connectivity using resting-state fMRI and neurological impairment in patients with cervical spondylosis and healthy controls.
This article was published in the following journal.

fMRI is the convolution of the hemodynamic response function (HRF) and unmeasured neural activity. HRF variability (HRFv) across the brain could, in principle, alter functional connectivity (FC) estim...
Transcranial magnetic stimulation (TMS) modulates activity at local and regions distal to the site of simulation. TMS has also been found to modulate brain networks, and it has been hypothesized that ...
Ensuring patient comfort and compliance by emphasizing reduced time frame for image acquisition, without compromising image quality is the key aspect with functional MRI examination. Multiband resting...
A major regulatory task of the organism is to keep brain functions relatively constant in spite of metabolic changes (e.g., hunger vs. satiety) or availability of energy (e.g., glucose administration)...
Disturbed hypothalamus-pituitary-adrenal axis function, which leads to excessive and prolonged hypercortisolemia, is a core feature of major depressive disorder (MDD). However, the relationships betwe...
The purpose of this study is to identify a core fMRI feature that determines migrainous brain and plastic fMRI features that changes with longitudinal courses of migraine.
The primary purpose is to compare with resting fMRI the functional networks of rest (RTS) in unipolar depression and in bipolar depression. Hypothesis : the main objective of this work is...
This study assess the putative persistence of neural damage using resting state fMRI after concussion in rugby player once they have clinically recovered. The hypothesis is that despite a ...
The aim of the study is to investigate the functional connectivity between the brain regions of the default mode network before and after a 40 min nap slot in the afternoon. The hypothesis...
The aim of this proposal is to investigate the effects of uneventful microsurgical and endovascular treatment of unruptured saccular non-giant anterior communicating artery [ACoA] aneurysm...
The period of time following the triggering of an ACTION POTENTIAL when the CELL MEMBRANE has changed to an unexcitable state and is gradually restored to the resting (excitable) state. During the absolute refractory period no other stimulus can trigger a response. This is followed by the relative refractory period during which the cell gradually becomes more excitable and the stronger impulse that is required to illicit a response gradually lessens to that required during the resting state.
The physiologic or functional barrier to GASTROESOPHAGEAL REFLUX at the esophagogastric junction. Sphincteric muscles remain tonically contracted during the resting state and form the high-pressure zone separating the lumen of the ESOPHAGUS from that of the STOMACH. (Haubrich et al, Bockus Gastroenterology, 5th ed., pp399, 415)
A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death. (From Adams et al., Principles of Neurology, 6th ed, pp348-9)
The third type of glial cell, along with astrocytes and oligodendrocytes (which together form the macroglia). Microglia vary in appearance depending on developmental stage, functional state, and anatomical location; subtype terms include ramified, perivascular, ameboid, resting, and activated. Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies. They have also been suggested to act in several other roles including in secretion (e.g., of cytokines and neural growth factors), in immunological processing (e.g., antigen presentation), and in central nervous system development and remodeling.
Volume of circulating blood in a region of the brain. It is a functional measure of the brain perfusion status which relates changes in this to changes in CEREBROVASULAR CIRCULATION that are often seen in brain diseases.
