[edit] Subjects

Subject group #1 (help)
Healthy Americans
Description: Healthy right-handed recruited from the university and surrounding community
Subjects/♂/♀: 116 / 58 / 58
Age: 22.9 ±5.5 (18–40)
Nationality: American
Approval: Washington University Medical Center Human Subjects Committee
Databases:

Group 1 of 116 healthy Americans with 58 males and 58 females were included in the study. The American group had a mean age of 22.9 with a range from 18 to 40. The study on the human subjects was approved by the Washington University Medical Center Human Subjects Committee.

[edit] Results

The neuroimages were spatially normalized to Colin27 template. For thresholding AlphaSim in AFNI was used ("Ward, 2000" is referenced)
