Depressed Brain

'The Depressed Brain' - Talking Point

Have you ever wondered what the more intricate reason is for why you get depressed? Why, when you take a walk in the park and step on some dog excrement, you feel like it would have to be you out of the many people walking in the park for this unfortunate thing to happen to and then suddenly the world is against you?

It is to do with the part of your brain called the amygdala, which is triggered when you’re depressed. Apparently, it is shown to be overactive during negative times in your life, so you overreact to negative situations.

Antidepressant tablets try to slow down this activity and try to help stimulate neurogenesis (production of new neurons) via increasing serotonin levels in your brain.
