Document Summary
Studies suggest that people with chronic depression have a smaller hippocampus: you can see this through a mri. To measure how much blood flow is going to the hippocampus, you would use fmri (function mri) The adult hippocampus is responsible for making and producing new neurons throughout your lifetime. Fewer of these neurons are made if you are: under stress sleep deprived under the influence of alcohol. Thousands of these cells are made every day, but most die within weeks. They survive with effortful learning: physical skill learning (learning a new sport) Example: skiing or surfing: learning, not just training, matters. 30 min meditation, 30 min aerobic exercise, 2x week for 8 weeks. The 4 neuronal truths: the brain makes new neurons, many, if not most, will die, learning keeps them alive, must be successful and effortful. New helplessness theory is based on hopelessness: pessimistic attitude, 1 or > negative life event, hopeless. Rank order things you like to do.
