A comprehensive approach that examines the intersection of multiple biological processes is necessary to elucidate the development of stress-related disorders. In a new study, investigators from McLean Hospital, a member of the Mass General Brigham healthcare system, working with colleagues at The University of Texas at Austin and Lieber Institute for Brain Development, uncovered both shared and distinct …

Does the way a person hears about an event shape their recollection of it later? In a new Journal of Neuroscience paper, Signy Sheldon and colleagues, from McGill University, explored whether different storytelling strategies affect how the brain stores that experience as a memory and recalls it later. The researchers created narratives with the same core events, …

Previous research has shown the vast mental and physical health benefits associated with yoga. Yoga practice can be divided into subcategories that include posture-holding exercise (asana), breathing (pranayama, Kriya), and meditation (Sahaj) practice. Studies measuring mental health outcomes have shown decreases in anxiety, and increases in cognitive performance after yoga interventions. Similar studies have also shown cognitive …

The brain is the most complex and intricate part of the human body, and yet many of us don’t recognize just how many functions it carries out on a daily basis. Inside your head, there are approximately sixty trillion neural connections (pathways between brain cells), and while the brain represents only 2–2.5% of the body mass, it consumes …
The vagus nerve represents the main component of the parasympathetic nervous system, which oversees a vast array of crucial bodily functions, including control of mood, immune response, digestion, and heart rate. It establishes one of the connections between the brain and the gastrointestinal tract and sends information about the state of the inner organs to …

Across a human life span, changes in cognition are expected to occur as individuals grow older. Most of the changes experienced in aging are related to a decline in fluid intelligence, defined as the capacity to solve problems and articulate ideas, to navigate new situations, and to acquire knowledge. On the other hand, crystallized intelligence, …

High-quality sleep and adaptive cognitive emotional regulation strategies can help to promote resilience to depression and anxiety when faced with negative or stressful experiences, according to new research published in the scientific journal Cortex. The researchers were interested in understanding why some individuals experiencing chronic stress develop mental health problems, while others do not. They believed …
Elevated inflammation is a risk factor for many psychiatric (e.g., depression) and somatic conditions (e.g., rheumatoid arthritis). Inflammation is influenced by psychosocial processes such as emotion regulation. Characterization of which emotion regulation characteristics impact inflammation could help refine psychosocial interventions aimed at normalizing health-harming inflammatory activity for individuals with psychiatric and somatic illnesses. We systematically reviewed the …
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 …
Students of human history are very aware of patterns and cycles that define our intergenerational experiences. The hope is that by discovering the systemic causes of failures in the past we can prevent or reduce the consequences of failures in the current age. Karl Marx hypothesized that the important cycles of history were the ones …
