The Modulatory Effects of Oxytocin and Vasopressin on Delta-beta Cross-frequency Coupling

The main aim of the study is to investigate whether intranasal oxytocin and vasopressin have effects on delta-beta cross-frequency coupling under resting-state and task conditions.

Study Overview

Detailed Description

A double-blinded, placebo-controlled, between-subject design is employed in this study. In a randomized order, a total of 120 healthy males and females are instructed to self-administer intranasal spray of oxytocin, vasopressin, or placebo. (1) 15-minute resting-state EEG data are collected 35 minutes after treatment. (2) Participants complete tasks including Stroop, GO/NOGO, and anxiety induction with behavioral (response time, accuracy, or rating) and EEG data being collected. Personality traits of subjects are assessed using validated Chinese version questionnaires including the Beck Depression Inventory (BDI-II), State-Trait Anxiety Inventory (STAI), Autism Spectrum Quotient (ASQ), and Adult ADHD Self-Report Scale (ASRS-v1.1). Participants are asked to complete Positive and Negative Affect Schedule (PANAS) when they just arrive, before resting state and after the tasks. Three blood samples (5 ml) are collected into 6 ml ETDA tubes when participants just arrive, before resting state recording and after all of the tasks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Resting-state EEG
Time Frame: 35-50 minutes after treatment administration.
Participants are asked to sit comfortably and look at a white cross fixation against a black background on the computer monitor for 15 minutes with delta-beta cross-frequency coupling as a main index.
35-50 minutes after treatment administration.
Behavioral indices in the tasks
Time Frame: 50-90 minutes after treatment administration.
Reaction time and accuracy are recorded in the emotional Stroop and Go/Nogo tasks. For the anxiety induction task, participants are instructed to rate their anxiety levels using a 9-point Likert scale within 4 seconds (1 = not at all, 9 = very anxious).
50-90 minutes after treatment administration.
Task-based EEG
Time Frame: 50-90 minutes after treatment administration.
EEG data are recorded in the emotional Stroop, Go/Nogo, and anxiety induction tasks. Delta-beta cross-frequency coupling will be calculated to do statistical analyses.
50-90 minutes after treatment administration.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
SCR in anxiety induction
Time Frame: 70-90 minutes after treatment administration.
Skin Conductance Response (SCR) data are recorded in the anxiety induction task under safe and anxious conditions.
70-90 minutes after treatment administration.
