Summary Introduction

To determine:

The conclusion from a positive correlation between BDNF levels and running distance.

Introduction:

BDNF is a protein present in humans. It is also known as Brain-derived neurotrophic factor. It is programmed by the BDNF gene. It is a neurotrophin family member (growth factors family). It is associated with the growth factor of canonical nerve. Neurotrophic factors are present in the periphery and the brain.

Researchers investigating the effect of exercise on cognitive functions conducted a con- trolled experiment in which rats were randomly assigned to sedentary (Sed), low-intensity exercise (Low-Ex), or high-intensity exercise (High-Ex) groups. During this exercise regi- ment, rats were also trained to navigate a specialized water maze, and their escape la tency, the time it took them to escape the maze, was recorded. The results of this experi- ment are depicted in the figure below. escape latency (sec) 100 80 60- 40- 20 0- day 10 day 11 Escape latencies during the training phase Based on the data above, day 12 (b) Identify the control group in the experiment. sed -- low-ex -- high-ex (a) Identify the dependent and independent variables in the experiment. day 13 Respond to each part in 3 to 4 complete sentences. (c) Compare the effects of low-intensity and high-intensity exercise on the rats' cognitive func- tion during the training period.
write an abstract regarding the two diffrent studies provided
A researcher wishes to determine if vitamin E supplements could increase cognitive ability among elderly women. In 1999 the researcher recruits a sample of elderly women age 75-80. At the time of the enrollment into the study, the women were randomized to either take Vitamin E, or a placebo for six months. At the end of the six month period, the women were given a cognition test. Higher scores on this test indicate better cognition. The mean and standard deviation of the test scores of 81 women who took vitamin E supplements was 27 and 6.9 respectively. The mean and standard deviation of the test scores of the 90 women who took placebo supplements was 24 and 6.2, respectively.C Computea 95% confidence interval for the mean difference in cognition test scores between Vitamin E and placebo group.
