neurobiology of psychedelic experience

Scientists have identified specific patterns of brain network reconfigurations that occur when people take both classical and non-classical psychedelic drugs. Their findings, published in NeuroImage, shed new light on how psychedelics affect the brain and consciousness. The authors behind the new study wanted to better understand the neurobiology of the psychedelic experience by examining the common …

vagus physiology: answers to critical questions you didn’t know you had – part III

In part III of our article on vagus physiology, we look at the treatment for these, until recently, little-known but critically important and widespread conditions of the vagus nerve which are the root cause of many illnesses for millions of people worldwide. In parts I and II of this article, we have laid a basic …

in sync brainwaves predict learning

Students whose brainwaves are more in sync with their classmates and teacher are likely to learn better than those lacking this โ€œbrain-to-brain synchrony,โ€ shows a new study by a team of psychology and education researchers. The findings, which appear in the journalย Psychological Science, offer new insights into the learning process.ย  โ€œThis is the first study …

software of life: bioelectric controls in a unique reprogrammable medium

How does the developing embryo know where to put the features of the face, the limbs, fingers, organs, bones and all those other amazing facets of our physiology? It has to do with the bodyโ€™s innate bioelectrical system, says Professor Michael Levin from Tufts University in the US. In a fascinating experiment, Levin showed that …

vagus physiology: answers to critical questions you didn’t know you had – part II

Can different pathophysiological mechanisms and risk factors leading to various diseases be linked with altered nerve transmission via one common pathway? The authors of a 2012 scientific article published in the journal,ย Clinical Science,ย (3) hypothesized that adequate vagal nerve activity reduces the risk of major diseases through common basic mechanisms.. There are 3 basic mechanisms that …

managing emotions better could prevent pathological aging

Negative emotions, anxiety and depression are thought to promote the onset of neurodegenerative diseases and dementia. But what is their impact on the brain and can their deleterious effects be limited? Neuroscientists at the University of Geneva (UNIGE) observed the activation of the brains of young and older adults when confronted with the psychological suffering of others. …

vagus physiology: answers to critical questions you didn’t know you had – part I

The vagus nerves are the nerves of life. They keep us alive by their innervation of the internal organs of the body and their interactions with the brain, spinal cord, cranial nerves, upper cervical spinal nerves, and sympathetic nervous system. Sensory functions of the vagus nerve are critical for conscious perception and for monitoring visceral …

the science of flow: heart brain coherence

Many contemporary scientists believe it is the underlying state of our physiological processes that determines the quality and stability of the feelings and emotions we experience. The feelings we label as positive actually reflect body states that are coherent, meaning "the regulation of life processes becomes efficient, or even optimal, free-flowing and easy,"[160] and the feelings …
