Chronic oxytocin improves neural decoupling at rest in children with autism: an exploratory RCT

What Was Tested

The paper reports a study of Oxytocin, published as a randomized controlled trial.

Shifts in peak frequencies of oscillatory neural rhythms are put forward as a principal mechanism by which cross-frequency coupling/decoupling is implemented in the brain.

During active neural processing, functional integration is facilitated through transitory formations of "harmonic" cross-frequency couplings, whereas "nonharmonic" decoupling among neural oscillatory rhythms is postulated to characterize the resting, default state of the brain, minimizing the occurrence of spurious, noisy, background couplings.

Who Took Part

PubMed indexes the participants as children, both men and women.

At the baseline, neural assessments of children with autism were compared with those of a matched cohort of children without autism (n = 40).

How the Study Was Run

The design is described as randomized and placebo-controlled.

Random assignment meant chance, not the researchers, decided who got Oxytocin and who got the comparison, which limits bias.

Some participants received a placebo instead of Oxytocin, giving a reference point.

What Was Measured

PubMed files the paper under topics including Oxytocin, Autism Spectrum Disorder, Theta Rhythm, Alpha Rhythm and Electroencephalography.

The authors tagged it with the keywords heart rate variability, neural rhythms and signal to noise.
