Jan 13, 2022 · Chronic, or long-term, stress can affect the size of your brain and even its genetic makeup. Many of these physical changes happen as a result of high cortisol levels and changes to the way your ...
The response of the brain to stressors is a complex process involving multiple interacting mediators that utilizes both genomic and non-genomic mechanisms from the cell surface to the cytoskeleton to epigenetic regulation via the cell nucleus. Resilience in the face of stress is a key aspect of a healthy brain, even though gene expression shows ...
Oct 28, 2022 · Stress hormones can also suppress neural pathways that are normally active in decision-making and cognition, and accelerate the deterioration in brain function caused by aging. They may worsen the damage caused by a stroke. And they can lead to sleep disorders — cortisol is also an important wakeful signal in the brain, so high cortisol ...
Hans Selye—the founder of the field of stress research—defined stress from a physiological viewpoint as “the nonspecific response of the body to any demand made upon it.” According to Selye, “anything that speeds up the intensity of life, causes a temporary increase in stress” (Selye, 1974).
Abstract. In order to survive and thrive, organisms must adapt to constantly changing environmental pressures. When there are significant shifts in the environment, the brain and body engage a set of physiological and behavioral countermeasures collectively known as the “stress response”. These responses, which include changes at the ...
Sep 25, 2015 · The brain is the central organ of stress and adaptation to social and physical stressors because it determines what is threatening, stores memories, and regulates the physiological as well as ...

Abstract. Stress is recognized as an important issue in basic and clinical neuroscience research, based upon the founding historical studies by Walter Canon and Hans Selye in the past century, when the concept of stress emerged in a biological and adaptive perspective. A lot of research after that period has expanded the knowledge in the stress ...
