This period saw the transition from a relatively rigid system of legal proofs which predetermined when there was sufficient evidence for a condemnation, to a system based on the free evaluation of the evidence by either professional judges or lay jurors. It is the central contention of this article that the reform of the criminal law of evidence can, to an important extent, be explained by two larger underlying ideological changes. These new ideas derived from a change in the epistemological and the political-constitutional discourses between the seventeenth and nineteenth centuries.
Story at-a-glance - Exercise produces large cognitive gains and helps fight dementia It promotes a process known as neurogenesis, i.
Mercola Scientists have been linking physical exercise to brain health for many years. In fact, compelling evidence shows that physical exercise helps build a brain that not only resists shrinkage, but increases cognitive abilities.
The featured article in Real Simple magazine2 highlights a number of brain-boosting benefits of exercise, including the following. In fact, research has shown that in most cases these drugswork no better than a placebo — and can also have serious side effects.
Swedish researchers3 have also teased out the mechanism by which exercise helps reduce stress and related depression.
As it turns out, mice with well-trained muscles have higher levels of an enzyme that helps metabolize a stress chemical called kynurenine.
Their finding suggests that exercising your muscles actually helps rid your body of stress chemicals that can lead to depression. According to the authors: We actually found the opposite: Women who sat for more than seven hours a day were found to have a 47 percent higher risk of depression than women who sat for four hours or less per day.
Those who didn't participate in any physical activity at all had a 99 percent higher risk of developing depression than women who exercised. To Boost Creativity, Get Moving! As noted in the featured article, exercise can also boost your creativity, and help you come up with new solutions to problems.
For example, researchers at Stanford University found that walking can increase creativity up to 60 percent. Walking opens up the free flow of ideas, and it is a simple and robust solution to the goals of increasing creativity and increasing physical activity. This information is completely contrary to what I was taught in medical school.
Hence deterioration and progressive memory decline was considered a more or less inevitable part of aging. According to John J.
Ratey, a psychiatrist who wrote the book Spark: The featured article cites research8 showing that those who exercise have a greater volume of gray matter in the hippocampal region of their brains, which is important for memory.
Findings highlight the relationship between regular physical exercise and brain structure during early to middle adulthood. Furthermore, these results suggest a strong biological basis for the role of aerobic fitness in maintaining and enhancing central nervous system health and cognitive functioning in older adults.
For example, one observational study11 that followed more than seniors, starting at age 70, found that those who engaged in the most physical exercise showed the least amount of brain shrinkage over a follow-up period of three years. BDNF is a remarkable rejuvenator in several respects. In your brain, BDNF not only preserves existing brain cells,12 it also activates brain stem cells to convert into new neurons, and effectively makes your brain grow larger.
Research13 confirming this includes a study by Kirk Erickson, PhD, in which seniors aged 60 to 80 who walked 30 to 45 minutes, three days per week for one year, increased the volume of their hippocampus by two percent.
The hippocampus is a region of your brain important for memory. The changes in the size of the hippocampus were correlated with changes in the blood levels of the brain-derived neurotrophic factor BDNF.
He called exercise "one of the most promising non-pharmaceutical treatments to improve brain health.A set of reading comprehension tasks (with extracts) focusing on three key areas: retrieving information, making inferences and writer's choice.

and helps with editing the journal. You should consult a physician before beginning a new diet or exercise program and discontinue exercise immediately and consult your physician if you experience pain, dizziness, or discomfort.
The results, if any, from the exercises may vary from person-to-person. Key points. Aerobic exercise, such as running, enhances adult hippocampal neurogenesis (AHN) in rodents.
Little is known about the effects of high‐intensity interval training (HIT) or of purely anaerobic resistance training on AHN. Genetically Engineered "Marathon Mouse" Keeps on Running Summary By enhancing the function of a single protein, Howard Hughes Medical Institute researchers have produced a "marathon mouse" with altered muscle composition and enough physical endurance to run twice as far as normal mice.
The faster you move the mouse, the longer the blue vector becomes. 2) Essay about Chapter 1 Lab Words | 4 Pages.
