    How Stress Is Making You Lose Your Mind

    "The stress hormone cortisol can kill, shrink, and stop the generation of new neurons in a portion of the brain called the hippocampus. (1) The hippocampus is critical for learning, memory and emotional regulation, as well as shutting off the stress response after a stressful event is over: all much-needed processes in both our professional and personal lives.

    Chronic stress can also shrink the medial prefrontal cortex. (2) This negatively affects decision making, working memory, and control of impulsive behavior. Stress also has the ability to affect stem cells, inhibiting access to the prefrontal cortex, where we plan complex cognitive behavior and moderate social interaction. The result is a brain that is less capable of learning and memory, and more prone to anxiety and depression.

    To make matters worse, these same stress hormones can increase the size and activity of a portion of the brain called the amygdala. (3) The amygdala is critical in the formation and storage of memories associated with highly emotional events. It pairs an event with a feeling, and this connection is stored away in our long-term memory so we can either avoid the event or seek it out in the future. The changes cortisol creates increase negative emotions such as fear, anxiety, and aggression."

    Thanks metta! Stress really is a poison.... Even fetuses are said to be adversely affected by the mother's stress levels (which is also why I'm pro-choice, purely because a mother who is even THINKING about aborting is probably someone who is stressed out for whatever reason about how having a baby, thus creating a negative environment for her baby in utero, and bringing a child into the world with less than a fighting chance).

    Exercise helps so much in stress relief!

    Thanks, Metta. I always look forward to your posts.

    I wasn't surprized that the article cited Robert Sapolsky. Highly recommend his books to anyone interested in this topic. He's also got an entire series of lectures on YouTube discussing biology and human behavior. Icing on the cake: he's an excellent writer.

    Also, I'd like to recommend The Shallows: what the Internet is doing to our brains, by Nicholas Carr. Carr writes about neuroplasticity, how the brain changes, physically, in response to its use. The takeaway? We're increasingly incapable of sustained thought.

    I think the wider, social implication of stress (which includes over stimulation) and living in a state of continual distraction, is loss of freedom, particularly in a consumer culture driven by advertising and its media minions.

    Introduction to Human Behavioral Biology

    Stanford professor Robert Sapolsky gave the opening lecture of the course entitled Human Behavioral Biology and explains the basic premise of the course and how he aims to avoid categorical thinking.
