Journal ArticleDOI
Dopaminergic Network Differences in Human Impulsivity
Joshua W. Buckholtz,Michael T. Treadway,Ronald L. Cowan,Neil D. Woodward,Rui Li,M. Sib Ansari,Ronald M. Baldwin,Ashley N. Schwartzman,Evan S. Shelby,Clarence E. Smith,Robert M. Kessler,David H. Zald +11 more
TL;DR: It is found that higher levels of trait impulsivity were predicted by diminished midbrain D2/D3 autoreceptor binding and greater amphetamine-induced DA release in the striatum, which was in turn associated with stimulant craving.
Journal ArticleDOI
Decreased single-photon emission computed tomographic [123I]beta-CIT striatal uptake correlates with symptom severity in Parkinson's disease.
John Seibyl,K. L. Marchek,Donald M. Quinlan,K Sheff,Sami S. Zoghbi,Yolanda Zea-Ponce,Ronald M. Baldwin,B. Fussell,Eileen O. Smith,D.S. Charney,Paul B. Hoffer,Robert B. Innis +11 more
TL;DR: The significant correlation of SPECT measures with motor severity suggests {123I}β‐CIT may be a useful Marchker of disease severity in PD.
Journal ArticleDOI
Mesolimbic dopamine reward system hypersensitivity in individuals with psychopathic traits
Joshua W. Buckholtz,Michael T. Treadway,Ronald L. Cowan,Neil D. Woodward,Stephen D. Benning,Rui Li,M. Sib Ansari,Ronald M. Baldwin,Ashley N. Schwartzman,Evans S. Shelby,Clarence E. Smith,David A. Cole,Robert M. Kessler,David H. Zald +13 more
TL;DR: These findings suggest that neurochemical and neurophysiological hyper-reactivity of the dopaminergic reward system may comprise a neural substrate for impulsive-antisocial behavior and substance abuse in psychopathy.
Journal ArticleDOI
Single photon emission computed tomographic imaging demonstrates loss of striatal dopamine transporters in Parkinson disease.
Robert B. Innis,John Seibyl,B E Scanley,Marc Laruelle,Anissa Abi-Dargham,E. A. Wallace,Ronald M. Baldwin,Yolanda Zea-Ponce,Sami S. Zoghbi,S. Wang +9 more
TL;DR: Results suggest that single photon emission computed tomographic imaging with [123I]beta-CIT may be useful for early diagnosis of the disorder, for monitoring the progression of the disease, and for distinguishing the idiopathic disorder from other Parkinsonian syndromes with more widespread pathology.
Journal ArticleDOI
SPECT imaging of dopamine and serotonin transporters with [123I]beta-CIT: pharmacological characterization of brain uptake in nonhuman primates.
Marc Laruelle,Ronald M. Baldwin,Robert T. Malison,Yolanda Zea-Ponce,Sami S. Zoghbi,Mohammed S. Al-Tikeriti,Elzbieta H. Sybirska,Ralph C. Zimmermann,Gary Wisniewski,John L. Neumeyer,Richard A. Milius,Shaoyin Wang,Eileen O. Smith,Robert H. Roth,Dennis S. Charney,Paul B. Hoffer,Robert B. Innis +16 more
TL;DR: It is suggested that [123I]β‐CIT will be a useful SPECT tracer of DA and 5‐HT transporters in living human brain.
