What is the region of the brain or chemicals in the brain that we can see emotion or thinking.And can we use electrode or drug to increase or degrees the emotion or thinking.

Why do some people have anger or depression what is wong with their brain and when does it become a disorder.They say dopamine release the pleasure center of brain and food ,drugs or alcohol release dopamine .

People that suffer from very bad addictions say the brain lacks dopamine and the drugs or alcohol acts as a cap for bad brain that lacks the dopamine other say it is in the genes.


But no one has measured what causes anger or depression or emotion like love.Why do we not do brain surgery for the chemical imbalance to treat disorders than a crude way to come up with a drugs.

Of course there are dozens of theories out there for each of those questions. But as for depression, it can be seen as the body becoming "stuck" in a sort of "fight or flight" response. That is, 20,000 years ago - if you were confronted by a bear in the middle the forest, your body goes into overdrive, pumping adrenaline and other hormones into the system to provide you with the energy needed either to fight your way out of the situation, or run and seek safety.

With depression, constant stressors can trigger a perpetual response that simply can't be maintained - it can result in pain, weakness, lethargy, and impaired cognition. It can be so debilitating that the individual can't move out of bed and may even want to kill themselves to make it stop. Thus, it's not just a function of neurotransmitters and a "chemical imbalance" but is a systemic condition that is currently treated with psychopharmaceuticals, but for which there are promising trials on drugs that don't act on the brain whatsoever.
