Researchers identified an abnormal link between the autonomic and central nervous system via communication between the heart and parts of the prefrontal cortex in women with generalized anxiety disorder.
Cardiovascular problems can alter gene activity in the hippocampus, increasing the risk for cognitive decline and memory deficits, a new study reports.
Exposure to energy drinks increases heart rate and impacts cardiovascular function, researchers report. Energy drinks may have a significant impact on human cardiomyocytes.
The brain suppresses the perception of the heartbeat, affecting our perception of other sensory stimuli. Researchers propose the brain's sensitivity to sensory stimuli depends on the cardiac cycle and the brain's perception of it.
Brain activity alters over the heartbeat cycle, helping us make sure certain information is kept out of our conscious experience. The findings provide a conceptual framework to explain how internal signals integrate into our conscious perception of the world.
Heart insufficiency has a negative impact on gray matter in the brain. Weak heart function was linked to decreased gray matter in areas of the brain associated with memory and learning, including the hippocampus and parietal medial cortex. This may increase the risk of Alzheimer's disease.
A new study report heartbeat irregularities connected with abnormalities in brain activity may be a biomarker for epilepsy in those who have suffered brain injury or infection.
By the time typical symptoms of Parkinson's appear and patients are diagnosed with the disease, 60% of people experience significant damage to the heart's connections to the sympathetic nervous system. Researchers have investigated where inflammation and oxidative stress occur in the heart, and how this relates to heart problems associated with Parkinson's.
A new study reports caffeine concentration, the equivalent of four cups of coffee, can promote the movement of a regulatory protein into mitochondria. This can enhance mitochondrial function and protect heart cells from damage.
Taking steps to improve your heart health early in life can help prevent brain shrinkage as you age, a new Neurology study reports. Researchers discovered people who had better heart health scores also had a higher average brain volume as a percentage of their total head size in middle age.
Researchers report that a type of lab-grown human nerve cells can partner with heart muscle cells to stimulate contractions.
Those who sleep and rise earlier appear to have better cardiovascular health, a new study reports.
