Effects On The Brain Researchers believe that — more important than levels of specific brain chemicals — nerve cell connections, nerve cell growth, and the functioning of nerve circuits have a major impact on depression. THALAMUS- Some research suggests that bipolar disorder may result from problems in the thalamus, which helps link sensory input to pleasant and unpleasant feelings.
Pt 3 HIPPOCAMUS- smaller in some depressed people, and research suggests that ongoing exposure to stress hormone impairs the growth of nerve cells in this part of the brain. AMYGDALA- Activity in the amygdala is higher when a person is sad or clinically depressed. This increased activity continues even after recovery from depression
