E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main aim of the trial is to investigate if the intranasal applied Oxytocin (vs. Placebo) leads to an increased modulation of the neural network of empathy in patients with high-functioning autism dependent on the genotype of the SNP rs53576 in the oxytocin receptor gene. |
Führt die Gabe von Oxytocin (vs. Placebo) zu einer verstärkten Modulation neuronaler Prozesse empathischen Erlebens bei bestimmten Genotypen des SNPs rs53576 (G>A) im Oxytocin-Rezeptor-Gen bei ASD? |
|
E.2.2 | Secondary objectives of the trial |
1. Influence of intranasal applied oxytocin on empathy in patients with high-functioning autism On the basis of recent publications it is expected, that intranasal applied Oxytocin leads to an attenuated activation of the amygdala and an increased activation of the neural network of empathy compared to placebo. 2. Influence of the genotypes of the SNP rs53576 in the oxytocin receptor gene on the activation of the neural network of empathy in patients with high-functioning autism. Intranasal applied oxytocin in carriers of the risk allele A of the SNP rs53576 in the OXTR (A/A and G/A) leads to an attenuated activation in the neural network of empathy [anterior insula, ACC (anterior cingulate cortex), amygdala, thalamus, PAG (periaqueductal gray), FG (fusiform gyrus)] during empathic processes.

1: Einfluss von Oxytocin auf Empathienetzwerke bei ASD Basierend auf neueren Publikationen wird erwartet, dass die Gabe von Oxytocin zu einer generellen Minderaktivierung der Amygdala und zu einer verstärkten Aktivierung des Empathie-Netzwerkes führt (Vergleich Placebo vs. Verum). 2: Einfluss des Genotypen des SNPs rs53576 im Oxytocin-Rezeptor-Gen auf Aktivierung des Empathie-netzwerkes bei ASD Unter Oxytocingabe kommt es während empathischer Prozesse bei Trägern des Risikoallels A des SNPs rs53576 im Oxytocin-Rezeptor-Gen (A/A und G/A) zu einer weniger starken Aktivierung im Empathie-Netzwerk (anteriore Insula, ACC, Amygdala, Thalamus, PAG, FG). |
