Researchers have discovered how the brain controls our breathing in response to changing oxygen and carbon dioxide levels in the blood.
The common myth that Anne Boleyn tried to speak after her untimely demise at the hands of her executioner may have scientific evidence behind it. Researchers explore how consciousness may remain intact for a period of time after death, and what that may mean for medical sciences.
According to a new study, poor physical fitness in middle age may be linked to lower brain volume in later life.
Decreased blood flow and blood oxygen levels to the hippocampus may explain symptoms of memory loss associated with Alzheimer's. Researchers say increasing hippocampal blood flow could reverse or protect against symptoms of the neurodegenerative disorder.
Chronic hypoxia can induce an inflammatory response with concomitant demyelination that can lead to future behavioral deficits, a new study reports.
Researchers directly measured oxygen levels in an intact brain and correlated it with neural activity. During normal activity, only 50% of oxygen is used for neural activity, the remaining 50% is required for glial cells and maintaining the metabolic rate of other nerve cells.
According to UT Dallas researchers, chronic cannabis users extract more oxygen from brain blood flow and have higher cerebral blood flow than nonusers.
According to a new study, during sensory stimulation, increases of blood flow are not precisely tuned to local neural activity, and this can have implications for fMRI neuroimaging.
