[edit] Subjects

Subject group #1 (help)
Healthy
Description: Subjects were healthy and heterosexual
Subjects/♂/♀: 23 / 11 / 12
Age: 33 (19–45)
Nationality: define nationality
Approval: Internal ethics committee of the University Medical Center Groningen
Databases:

Group 1 of 23 healthy with 11 males and 12 females were included in the study. The group had a mean age of 33 with a range from 19 to 45. The study on the human subjects was approved by the Internal ethics committee of the University Medical Center Groningen.

The subjects have previously been included in other studies by the group in genital stimulation[1][2] and orgasm.[3][4]

[edit] Scanning

PET Scanning (help)
Scanner: CTI/Siemens Ecat Exact HR+
Radiotracer: Oxygen-15 Water
Laboratory: missing laboratory

Using the radiotracer Oxygen-15-Water PET scans were acquired with a CTI/Siemens Ecat Exact HR+.


[edit] Results

SPM5 was used for the processing and analysis. Talairach coordinates are reported with respect to "MNI" and the statistical threshold set on <0.001 uncorrected. Some coordinates have indication for survival on the <0.05 FWE cluster corrected level (Table 1 text, page 3092).
