详细说明

The objective of the present study is to determine whether intranasal oxytocin (IN-OXT) effects on blood oxygenation level-dependent functional magnetic resonance imaging (BOLD fMRI) in the amygdala vary as a function of dose and latency. In particular, the investigators plan to compare effects of three different IN-OXT doses (12, 24, and 48 international units, IU) and three different dose-test latencies of IN-OXT administration (task starting at 15, 45 and 75min after administration) on established neural and behavioural correlates of emotion processing. As effects of OXT are particularly promising in autism, the investigators further want to investigate how autistic-like traits influence the OXT effects in exploratory post-hoc analyses

主要结果指标

结果测量
措施说明
大体时间
Neural substrates of emotion processing, measured via blood-oxygen-level dependent signal in the amygdala
大体时间:45min after nasal spray administration

Magnetic resonance imaging (MRI) will be performed to measure blood-oxygen-level dependent signal in response to emotional face stimuli of varying intensity. The investigators specifically plan to investigate amygdala response to fearful faces, as this subcortical region has repeatedly been reported to show activation changes after OXT treatment.

Dose-test latency varies between the different treatment arms (i.e. imaging starts 15min [arm 1], 45min [arm 2,4 and 5] or 75min [arm 3] after nasal spray administration).

次要结果测量

结果测量
措施说明
大体时间
Ratings of emotional faces
大体时间:45min after nasal spray administration

During each trial, subjects are asked to use a button response grip to indicate whether they perceived the depicted face as neutral, fearful or happy.

Depending on the treatment arm, ratings are recorded 15min (arm 1), 45min (arm 2,4 and 5) or 75min (arm 3) after nasal spray administration.

大体时间:10 min before and 105 min after nasal spray administration
Positive and negative affect is assessed via self-rating questionnaire 'The Positive and Negative Affect Schedule' using a categorical 5 point scale.

Plasma oxytocin concentrations
大体时间:immediately before the nasal spray administration and immediately after the fMRI experiment

Modulatory effects of autistic like traits on neural and behavioral outcome measures
大体时间:screening session, ~7days prior to imaging session
Autistic like traits are assessed via Autism Spectrum quotient in a screening session, preceding the testing sessions. The investigators expect pronounced OXT effects in subjects with high autistic-like traits.
