Now I have 4 more questions.

1.) Does the loss of pleasure activity due to depression equal out to the amount of activity gained in the amygdala?

2.) If it's not just the amygdala that gains activity during depression, but other brain regions that are responsible for negative emotions as well as controlling those emotions, does this overall activity of the amygdala plus these other brain regions equal out to the amount of pleasure activity that is lost during depression?

3.) If so, what are these other brain regions that gain activity during depression?

4.) Does the loss of pleasure activity due to depression equal out to the amount of activity the brain is using in an attempt to gain back pleasure?

So basically what I'm asking is if what is lost during depression (pleasure) is equally made up for both in terms of an active amygdala and other brain regions responsible for negative emotion/control as well as the brain trying to gain back pleasure. And that if a combination of those two things is equally (or even is greater) than the loss of pleasure activity during depression.

The reason I ask this is because if my brain does not equally (or even greater) make up emotionally for the lack of pleasure during depression, then I feel that my mind has died emotionally from depression rather than making up for that loss in the form of negative emotion/controlling negative emotion and, of course, attempting to gain back pleasure. Even if it's negative emotions (the active amygdala) that equally makes up for the lack of pleasure, that makes me feel emotionally "alive" rather than emotionally dying off through depression.
