I always wanted to understand the why rather than just the what. Why does grief hurt so much? Why does the death, the permanent absence of this person with whom you are bonded, result in such devastating feelings, and lead to behavior and beliefs that are inexplicable, even to you? I felt certain that part of the answer could be found in the brain, the seat of our thoughts and feelings, motivations, and behaviors. If we could look at it from the perspective of what the brain is doing during grief, perhaps we could find the how, and that would help us understand the why.
