Intranasal Oxytocin Improves Interoceptive Accuracy and Heartbeat-Evoked Potentials During a Cardiac Interoceptive Task

What Was Tested

This randomized controlled trial paper looks at Oxytocin.

Using a double-blind, placebo-controlled, between-participant design, the researchers recruited 72 healthy male participants who performed a cardiac interoceptive task during electroencephalograph and electrocardiograph recording to examine whether intranasal administration of the neuropeptide oxytocin could modulate interoceptive processing.

The researchers also collected data in a resting state to examine whether the researchers could replicate previous findings.

Why It Was Studied

Understanding the mechanism that underlies interoceptive processing, particularly its modulation, is therefore of great importance.

Who Took Part

The study group was 72 participants.

By PubMed's age tags, the people studied were young adults and adults, men only.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Oxytocin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Blinding on both sides kept the participants and researchers unaware of who received Oxytocin.

A placebo (an inactive look-alike) gave the Oxytocin group a baseline to be compared against.
