Brain regions in relation to stress and anxiety
Dr John Kenworthy provides a well-constructed and interesting description of how different brain regions interact to help us deal with events that are stressful. Of particular interest here is that peripheral and central factors play together to make sure we adapt to challenges.
Stress, depression and neurotransmission
This video deals with neurotransmitter and other brain changes associated with depression as well as with stressors (depression and stress are often linked). In addition, this video describes linkages between stressors, genetic factors, and depression.
Chronic stress and allostatic load
As you’ve now heard repeatedly, chronic stressors can undermine various aspects of our well-being. This vimeo.com video is a very good presentation of the pathophysiological consequences of chronic stressors. This includes various neuroendocrine and neurotransmitter changes in relation to pathological conditions. It covers a lot of material and might be a bit heavy for a health psychology course. Still, even if you don’t get all the fancy words, it would be good to see how stressful events can be translated into disease through neurobiological processes.
Erasing stress memories
Memories occur because with experiences the connections (synapses) are strengthened. These strong memories may be involved in pathological conditions such as depression and PTSD, which could affect physical disorders. Is it possible to erase memories by somehow weakening synaptic strength, and if so, can it be done selectively? Check out this video for some very provisional answers.
