A lot of leading-edge information on gut health and the connection with brain function is very new. Here are a few resources to help you learn more about these ideas in general.
Brain Regions Affect by Anhedonia This is an academic article describing the reward mechanism in the brain affected by anhedonia and depression. https://academic.oup.com/ijnp/article/22/2/105/5098511?utm_source=yahoo&utm_medium=referral&utm_campaign=in-text-link
RadioLab Gut Series RadioLab out of New York did a 3-part series on the gut and actually makes the ideas interesting and fun. This link contains 3 different interviews, and the second one on “Gut Feelings” is particularly relevant for gut health and mental health. Click on the link to listen to all three interviews, and click on the “Gut Feelings” link to listen to the second one. http://www.radiolab.org/story/197112-guts
New research on Positive Affect Treatment (PAT): This seems to be one of the more promising research studies on anhedonia. PAT is a similar approach to what we use in the Emotional Flatlining Brain Training Program (Tab above on Overcoming Flatlining).https://pubmed.ncbi.nlm.nih.gov/27699943/
