Emerging scientific knowledge such as the role of epigenetics and neuroplasticity—the brain's capability to constantly rewire with every action, experience, thought—is fundamentally changing our understanding potential impact we can have on brain. Our brain is formed by habits in interaction body, environment, influenced lifestyle, successes, failures, traumas. Neuroplasticity proves that stude...

TO THE EDITOR: It is with great interest that we read the paper entitled " Post-traumatic Stress Disorder Is Associated With Irritable Bowel Syndrome in African Americans " by Iorio et al. 1 The authors investigated the potential association between irritable bowel syndrome (IBS) and post-traumatic stress disorder (PTSD) in an urban African American (AA) population. The results demonstrate that...

he concept of neuroplasticity — the ability of the nervous system to change its structure and function — has captured the imagination of clinicians, researchers and the general public. 1 The ability of the brain to reorganise itself is remarkable. For example, people who are visually impaired engage their visual cortex for fine sensory discrimination when using their hands. In these situations,...

In human and experimental models of heart failure there is widespread change in the sympathetic nervous system. This involves preferential activation of the sympathetic nervous outflow to the heart, impairment of norepinephrine reuptake by sympathetic nerves, and reduction of the content of norepinephrine in the failing myocardium, attributable in part to sympathetic neuronal rarefaction.1–4 Mi...
