Hypothesis9 1: Evidence from studies of nuclear and mitochondrial DNA extracted from Neanderthal fossils and humans points to fascinating hypotheses concerning the types of interbreeding that occurred between these two species.
Rewiring the Stress Response: A New Paradigm for Health Care. Hypothesis9 1: In describing the conceptual basis of a stress intervention method, Emotional Brain Training EBTa program which integrates advances in neuroscience and stress physiology, we propose a new paradigm for health care.

The aquatic ape hypothesis (AAH), also referred to as aquatic ape theory (AAT) and more recently the waterside model, is the idea that the ancestors of modern humans were more aquatic and as such were habitual waders, swimmers and divers. The hypothesis in its present form was proposed by the marine biologist Alister Hardy in , who argued that a branch of apes was forced by competition.
Many health care treatments focus on managing symptoms of stress-related disorders. In modern society stress is primarily psychological in nature and in its chronic form, the result of allostatic non-homeostatic neural circuits that amplify and prolong stress.
The result is cognitive, emotional, behavioral and physiologic dysregulation resulting in wear and tear allostatic load. The effectiveness of treating any one stress symptom is likely decreased because of the persistent allostatic state.
Emerging understanding of neuroplasticity suggests that this circuitry is capable of change. EBT is based on the repeated use of techniques that mirror secure attachment and optimal self-regulatory processing to alter allostatic circuits through the process of reconsolidation, therefore decreasing allostatic load.
This results in an improved state of well-being. We hypothesize that decreased dominance of allostatic neuronal circuits leads to improved health outcomes, offering a new paradigm for health care. Introduction Many diseases including obesity, irritable bowel syndrome, gastroesophageal reflux disease, depression, anxiety, chronic pain and headaches are symptoms of stress or exacerbated by stress.
Identifying and modifying the brain circuits that trigger maladaptive stress responses should result in overall health improvement and likely decrease reliance on medications, procedures and devices. The hypothalamic-pituitary-adrenocortical axis HPA and the sympathetic-medullo-adrenal SMA system are activated in response to a stressor or fear.
Their prolonged or repeated activation interferes with most physiological systems, resulting in increased risk for physical and psychiatric disorders Links between stress and disease have been reported for depressionobesity and cardiovascular disease Each of the top ten causes of death in the United States is caused by or exacerbated by stress InLaurel Mellin began developing a treatment program for obesity 19—20aimed at decreasing the drive to overeat; the program has since evolved into a method of training adults and children in the skills of self-regulation called Emotional Brain Training EBT.
Over time, the method was informed by emerging neuroscience research in the areas of neuroplasticity, emotion research, stress biology and attachment theory.
The neuroscience of rewiring self-regulation utilized by EBT is based on physiologic brain states of stress. The skills used to rewire the stress response are based on four core concepts enumerated below. The full-blown stress response evolved in reaction to an imminent threat to survival — it is triggered rapidly and non-specifically However, this kind of threat is rare in modern society leading to an often inappropriate triggering of the full-blown stress response.
The wiring that triggers this unnecessary, amplified or prolonged stress response is stored in the unconscious implicit memory systems 23 via the HPA and SMA axes Those early connections, especially before the age of three, or later in life during periods of trauma, form the basis for the circuitry of resiliency and health These circuits may be effective or ineffective.
Each new stress stimulus is compared with internal representations of past experiences stored in our memory. Each circuit is the product of neurons being co-activated in response to a stressor, leaving behind a propensity to co-activate in the same pattern again.
This increased likelihood of activation of synapses that have a history of strong previous activation — long-term potentiation — is the basis for long-term memory and learning In probability theory and statistics, a unit root is a feature of some stochastic processes (such as random walks) that can cause problems in statistical inference involving time series models.A linear stochastic process has a unit root if 1 is a root of the process's characteristic caninariojana.com a process is non-stationary but does not always have a trend.
The characteristics of a good hypothesis are many.
The most important ones include being simple and clear. This means that the hypothesis should be concise at to the point.
Paul Andersen describes three main characteristics of life that are conserved in all organisms on the planet. The universal genetic code, the central dogma of biology, and shared metabolic pathways give us details of the original universal ancestor.
A hypothesis is not simply a wild guess. The experiment sets out to prove or disprove the hypothesis. The individual conducting the experiment must write the hypothesis in simple, concise language. This guarantees the hypothesis is testable.
