Fundamentally, a depressed brain looks just like any other brain. In fact, there’s no brain scan, MRI, EEG or any other medical test that can definitively diagnose depression, and it’s not understood in detail like other brain disorders. While we know the neurochemicals involved and many contributing factors, the truth is we really don’t know the neural causes of depression or what’s a cause and what’s a symptom even.
At the most basic level, depression is just the routine activation of certain brain circuits, which we all have, in specific patterns that result in depressive symptoms in a person.
