Age, sex and laterality effects on cerebral glucose metabolism in healthy adultsMark W Willis
Biological Psychiatry Branch, National Institute of Mental Health, 10 Center Drive MSC 1272, Bethesda, MD 20892 1272, USA
Psychiatry Res 114:23-37. 2002..These findings contribute toward a convergence in the literature, and the regression models of CMRglc vs. age serve as a normative database to which patients may be compared...
Intensity-dependent regional cerebral blood flow during 1-Hz repetitive transcranial magnetic stimulation (rTMS) in healthy volunteers studied with H215O positron emission tomography: II. Effects of prefrontal cortex rTMSAndrew M Speer
Biological Psychiatry Branch, National Institute of Mental Health, National Institutes of Health, Building 10 Room 5N234, Bethesda, MD 20892-1430, USA
Biol Psychiatry 54:826-32. 2003....
Preliminary findings of uncoupling of flow and metabolism in unipolar compared with bipolar affective illness and normal controlsRobert T Dunn
Biological Psychiatry Branch, National Institute of Mental Health, NIH, 10 Center Drive MSC 1272, Bethesda, MD 20892 1272, USA
Psychiatry Res 140:181-98. 2005....
Interregional cerebral metabolic associativity during a continuous performance task (Part I): healthy adultsMark W Willis
Uniformed Services University of the Health Sciences, PHS, HHS, Bethesda, MD, USA
Psychiatry Res 164:16-29. 2008..These analytical data may help to confirm known functional and neuroanatomical relationships, elucidate others as yet unreported, and serve as a basis for comparison to patients with psychiatric illness...
Left prefrontal-repetitive transcranial magnetic stimulation (rTMS) and regional cerebral glucose metabolism in normal volunteersTimothy A Kimbrell
Biological Psychiatry Branch, NIMH, NIH, Bethesda, MD 20892, USA
Psychiatry Res 115:101-13. 2002..While these results are in the predicted direction, further studies using other designs and higher intensities and frequencies of rTMS are indicated to better describe the local and distant changes induced by rTMS...
Principal components of the Beck Depression Inventory and regional cerebral metabolism in unipolar and bipolar depressionRobert T Dunn
Biological Psychiatry Branch, NIMH, NIH, Bethesda, Maryland 20892-1272, USA
Biol Psychiatry 51:387-99. 2002..Thus, different depressive symptom clusters may have different neural substrates in unipolars, but clusters and their substrates are convergent in bipolars...
Intensity-dependent regional cerebral blood flow during 1-Hz repetitive transcranial magnetic stimulation (rTMS) in healthy volunteers studied with H215O positron emission tomography: I. Effects of primary motor cortex rTMSAndrew M Speer
Biological Psychiatry Branch, National Institute of Mental Health, National Institutes of Health, Building 10 Room 5N234, Bethesda, MD 20892-1430, USA
Biol Psychiatry 54:818-25. 2003..CONCLUSIONS: This study demonstrates that 1-Hz rTMS delivered to the primary motor cortex (M1) produces intensity-dependent increases in brain activity locally and has associated effects in distant sites with known connections to M1...

Department of Psychiatry, University of Western Ontario, London, Ontario, Canada
Biol Psychiatry 64:327-35. 2008..However, neural responses arising in the early aftermath of a traumatic event have not been studied...
Regional cerebral glucose utilization in patients with a range of severities of unipolar depressionTim A Kimbrell
North Little Rock VA Medical Center (TAKi, North Little Rock, Arkansas, USA
Biol Psychiatry 51:237-52. 2002..CONCLUSIONS: Areas of frontal, cingulate, insula, and temporal cortex appear hypometabolic in association with different components of the severity and course of illness in treatment-resistant unipolar depression...
