23 The program appears to be a useful research tool in a PhD student laboratory.41 The MaZda package is available on the Internet.33 So far more than 300 researchers from all over the world have downloaded it onto their computers.

The recent development of neuroimaging technologies that permit in vivo characterization of the anatomical, physiological, and receptor pharmacological correlates of mood disorders have enabled significant advances toward delineating the neurobiological correlates of mood disorders. Because these conditions were not associated with gross brain pathology Inhibitors,research,lifescience,medical or with clear animal models for spontaneous, recurrent, mood episodes, the availability of tools allowing noninvasive assessment of the human brain proved critical to illuminating the pathophysiology of major depressive disorder (MDD) and bipolar disorder (BD). The results of studies applying imaging technologies and postmortem studies have guided clinical neuroscience toward models in which both functional and structural brain pathology Inhibitors,research,lifescience,medical play roles

in the pathogenesis of mood disorders. Longitudinal positron emission tomography (PET) imaging studies of MDD and BD identified abnormalities of regional cerebral glucose metabolism and cerebral blood flow (CBF), which, in some cases, persisted beyond Sitaxentan symptom remission, and in other cases appeared mood state-dependent (reviewed in reference 1; Figure 1). These reversible abnormalities presumably reflect areas where metabolic activity increases or decreases to mediate or respond to emotional and cognitive manifestations of the depressive syndrome, because local glucose metabolism and CBF (which is tightly coupled to glucose metabolism) reflect summations of the energy utilization associated with terminal field synaptic transmission during neural activity.
