Diminished cardiac vagal tone in schizophrenia: Associations to brain laterality and age of onset. Biol. Psychiatry 1997, 41, 612–617. [Google Scholar] [CrossRef] [PubMed] Thayer, J.F.; Lane, R.D. Claude Bernard and the heart-brain connection: Further elaboration of a model of neuro...
Microglial cells are the most sensitive sensors of brain pathology. They activate when signs of brain damage or nervous system dysfunction are detected. The “activated microglial cell” has the ability to release a large number of substances that can be harmful or beneficial to surrounding cells....
Heart Rate Variability Explained Yourheart rateis the number of heartbeats you have in a minute. Your heart rate depends on what you're doing at the time. So, if you're resting or relaxed, your heart beats slower, and if you're moving or stressed, your heart beats faster. Your body a...
Children with congenital heart disease (CHD) are living longer due to effective medical and surgical management. However, the majority have neurodevelopmental delays or disorders. The role of the placenta in fetal brain development is unclear and is the
Old age is associated with large elastic artery stiffening that, with time, has consequences on the heart (hypertrophy), brain and kidney (microvascular damage), which leads to heart failure, cognitive impairment, and renal failure. Successful aging (ie, a delay of central artery stiffening), ca...
(Figs.4and5). In the inner curvature of the heart, the right wall of the atrioventricular canal continues into the caudal part of the interventricular foramen. Rightward expansion of the confluent part of these structures across the muscular ventricular septum has produced a direct connection ...
We explained what the doctor had said, but how much he heard at that point I have no idea. But when he finally stated opening his eyes, that left one looked the worst I’d ever seen it. Almost black-red. The bottom part of the eyeball was actually swollen out a little over the ...
"We also identified a significant relationship between stress-associated brain activity and bone marrow activity in these individuals. Together, the findings provide insights into a potential mechanism that may contribute to the 'heart-brain connection'." In the first study to look at brain scans us...
and it's a genuine heart condition. Researchers have now learned more about the physiological mechanisms that can contribute to the problem. The findings, which werereported in theEuropean Heart Journal, suggest that the connection between the heart and brain plays a significant role, and that som...
Despite such technique provide specific focal epicardial photostimulation to determine cell type dependent responses, due to tight electronic connection between ChR2 expressed cells and non-ChR2 expressing cells, such cell-type dependent responses may not be accurate. To enable timely and spatially ...
