I will praise thee; for I am fearfully and wonderfully made:
Psalm 139:14
"A research team has discovered a group of cells in the brain that may function as a ‘master-controller’ for the cardiovascular system.
“Our study reveals how the brain directs blood flow to different parts of the body, a finding which has puzzled neuroscientists for many years,” said Macquarie University’s Dr. Simon McMullan.
The researchers identified one critical group of cells in the medulla oblongata, that send connections to multiple cardiovascular targets, suggesting a preeminent role for these cells.
In a follow-up study, they rendered those same brain cells sensitive to laser light, a technique called optogenetics, allowing them to control their activity with the flick of a switch.
The brain cells were found to simultaneously exert influence on multiple regions of the body, including the heart and the blood vessels of the fore- and hindlimbs, suggesting that the function of these cells is to coordinate activity across the cardiovascular system as a whole.
“We found that brain cells broadcast their message to many different targets to co-ordinate global control of blood flow,” Dr. McMullan said."
