The mind-body connection: not just a theory anymore

The field of psychoneuroimmunology has witnessed an explosion of empirical findings during the last two decades. Research has documented the mechanisms through which stressful emotions alter white blood cell function. Stress diminishes white blood cell response to viral infected cells and to cancer cells.

The science of how diet can change the way sugar tastes

Taste perception appears to be controlled by dopamine in fruit fly models. Tracing the neural pathway, researchers found the same pathways were associated with controlling learning and memory. The network also appears to enhance taste sensations. Researchers also discovered eating lots of sugar suppresses sweet taste perception.

A Gut-to-brain Circuit Drives Sugar Preference and May Explain Sugar Cravings

Sweet tasting foods don’t only trigger the taste buds, they also switch on a neurological pathway that begins in the gut. In the intestines, signals of sugar ingestion travel to the brain, sparking an appetite for more sweet foods. However, this pathway only responds to sugars, not artificial sweeteners.

Aerobic exercise training linked to enhanced brain function

People with a genetic predisposition to Alzheimer’s disease can benefit significantly from a six-month aerobic training program. Aerobic exercise helps improve brain glucose metabolism and executive function, in addition to increasing cardiorespiratory fitness.

This study is a significant step toward developing an exercise prescription that protects the brain against AD, even among people who were previously sedentary,” explained lead investigator Ozioma C. Okonkwo, PhD, of the Wisconsin Alzheimer’s Disease Research Center, University of Wisconsin School of Medicine and Public Health.

When Damaged, The Adult Brain Repairs Itself by Going Back to The Beginning

When adult brain cells are injured, they revert to an embryonic state, according to new findings published in the April 15, 2020 issue of Nature by researchers at University of California San Diego School of Medicine, with colleagues elsewhere. The scientists report that in their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

The Science Of How The Mind Affects The Immune System

Psychoneuroimmunology is a relatively new study on how the mind influences the immune system. There is conclusive research that indicates that our thoughts and feelings have a direct affect on our immune system function. The aim of this article is to breakdown this science into a simple to understand format with practical applications.
