Blood Oxygen Level-Dependent Signal Variability Is More than Just Noise

Blood oxygen level-dependent signal variability is more than just noise.

Functional magnetic resonance imaging (fMRI) research often attributes blood oxygen level-dependent (BOLD) signal variance to measurement-related confounds. However, what is typically considered "noise" variance in data may be a vital feature of brain function. We examined fMRI signal variability during fixation baseline periods, and then compared SD- and mean-based spatial patterns and their r...

Sleep Apnea: More than Just a Noise

Obstructive sleep apnea is a sleep disorder of airflow at the nose and mouth during sleep. Patients with undiagnosed sleep apnea represent a major public health problem. Dental professionals have a unique doctor patient relationship that can help them in recognizing the sleep disorder and managing the patients along with a physician or a sleep specialist. Oral appliance therapy is an important ...

Altered blood oxygen level-dependent signal variability in chronic post-traumatic stress disorder during symptom provocation

BACKGROUND Recent research suggests that variability in brain signal provides important information about brain function in health and disease. However, it is unknown whether blood oxygen level-dependent (BOLD) signal variability is altered in post-traumatic stress disorder (PTSD). We aimed to identify the BOLD signal variability changes of PTSD patients during symptom provocation and compare t...

More than just vanilla.

Septic shock: treating more than just blood pressure.

Technology: Anti-inflammatory therapy for the treatment of septic shock Use: Sepsis or septic shock, which occurs when the host’s response to infection is excessive, is the fourth leading cause of long-stay intensive care admissions. Death may occur despite antimicrobial therapy if the host response to infection is either excessive or insufficient (Fig. 1); in fact, mortality has been reported ...
