Stress and the Gut-Brain Axis Subscribe

Do some research to define the terms enteric nervous system, and microbiome. Then read the article about the Gut-brain axis: How the microbiome influences anxiety and depression by Foster and Neufeld (2013) in Trends in Neuroscience. For this discussion, explain how our microbiome contributes to digestion, and how microbes can activate pathways in the CNS. How does this relate to digestion?

Stress and Reproduction Subscribe

Stress has been related to low fecundity (reproductive success) in all animal populations. Evolutionarily, the stress pathway that enables prey to escape predators and animals to evade danger can have harmful effects when activated over long periods of time. In populations of animals, limited resources and low nutrition trigger pathways of response to the long-term stressors associated with overcrowding that result in low reproductive success. Do a little research on infertility in the United States. How does the stress response relate to infertility in our modern population?
