Cerebral blood flow and personality: a positron emission tomography study reports a personality neuroimaging study with positron emission tomography. The personality trait extraversion/introversion was assessed with the NEO Five-Factor Inventory

[edit] Subjects

Subject group #1 (help)
Healthy normals
Subjects/♂/♀: 18 / 10 / 8
Age: 28.9 ±8.5 (19–48)
Nationality: American
Approval: University of Iowa Human Subjects Institutional Review Board
Databases:

Group 1 of 18 healthy normals with 10 males and 8 females were included in the study. The American group had a mean age of 28.9 with a range from 19 to 48. The study on the human subjects was approved by the University of Iowa Human Subjects Institutional Review Board.

[edit] Scanning

PET Scanning (help)
Scanner: GE
Radiotracer: Oxygen-15 Water
Laboratory: missing laboratory

Using the radiotracer Oxygen-15-Water PET scans were acquired with a GE scanner..


[edit] Results

For thresholding "a correlation threshold of 0.60 (p<0.005, uncorrected for multiple comparisons) with introversion/extraversion and a size criterion of at least 10 contiguous voxels were selected." (end of method section)

The neuroimages was analyzed with their BRAINS software and spatially normalized to Talairach space (method section, table caption).
