How Your Heart Influences What You Perceive and Fear | Jordana Cepelewicz Quanta Magazine @quantamag — “In the late 19th century, the psychologist William James and the physician Carl Lange proposed that emotional states are the brain’s perception of certain bodily changes in response to a stimulus — that a pounding heart or shallow breathing gives rise to emotions like fear or anger rather than vice versa. Researchers have since found many examples of physiological arousal leading to emotional arousal, but they wanted to delve deeper into that link. The heartbeat provided the perfect means to do so.” “Cardiac activity can be divided into two phases: systole, when the heart muscle contracts and pumps out blood, followed by diastole, when it relaxes and refills with blood. Beginning in the 1930s, scientists found that systole dampens pain and curbs startle reflexes. Further work traced this effect to the fact that during systole, pressure sensors send signals about the heart’s activity to inhibitory regions of the brain. This may be useful because, while the brain must constantly balance and integrate internal and external signals, “you cannot pay attention to everything at once,” said Ofer Perl, a postdoctoral research fellow at the Icahn School of Medicine at Mount Sinai in New York. Experiments even showed that people were more likely to forget words that were presented exactly at systole than words that they saw and encoded during the rest of the cardiac cycle.” — Link in @hhpfoundation bio to article . . . . #brigalife #brigalifexperience #lungs #HHPFoundation #breathwork #breath #breathe #slowbreathing #diaphragm #pranayama #yoga #respira #resonanciaconsciente https://www.instagram.com/p/CoVU-govb4K/?igshid=NGJjMDIxMWI=
