A 45 year old woman presents to her primary care physician complaining of fatigue and headache. Over the past month she had trouble sleeping, difficulty concentrating, and episodes of crying for no reason. In addition, she says that she feels sad and worthless. The neurologic pathway most likely responsible for this symptoms is
A. meso-limbic-cortico pathway
B. locus ceruleus pathway
C. nucleus ambiguous pathway
D. glycolytic pathway
E. Nucleus accumbens pathway
The patient has depressive symptoms, As long as I know, two major transmitters are involved in the pathophysiology of depression:
1)Serotonin: A main neurotransmitter in Raphe nuclei, which has been strongly associated with brain dysfunction, especially mood disorders such as depression. 2)Norepinephrine: A main neurotransmitter in Locus ceruleus, which may figure in clinical depression, panic disorder, and anxiety.
In the question, so I choose B. Locus ceruleus pathway.

u r right. I'm also not sure about my answer; however, the mesolimbic pathway is a dopaminergic pathway which is mainly associated with the negative symptoms of schizophrenia.
