    Neuroreport 14:325-8. 2003
    ..The increased responsivity observed in the posterior cingulate and dorsolateral prefrontal cortices is consistent with the hypothesis that panic disorder patients engage in more extensive memory processing of threat-related stimuli...

    Richard J Maddock
    Department of Psychiatry, University of California Davis Medical Center, Sacramento, California 95817, USA
    Biol Psychiatry 73:1111-9. 2013
    ..However, prior studies in PD have not measured activity-dependent changes in brain metabolites other than lactate. Here we examine activity-dependent changes in both lactate and glutamate plus glutamine (glx) in PD...

    Hum Brain Mapp 18:30-41. 2003
    ..The results also extend prior findings that evaluating emotional words consistently activates the subgenual cingulate cortex, and suggest a means of probing this region in patients with mood disorders...

    ..10). These results suggest that a neocortical GABA deficit in subjects with schizophrenia leads to impaired cortical inhibition and that GABAergic synaptic transmission in visual cortex plays a critical role in OSSS...
