Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Two acute treatment (24 IU each) conditions including; a) intranasal placebo, and b) intranasal oxytocin (Syntocinon, Novartis, Switzerland). The two treatment conditions will be separated by a minimum of 1 week (washout period). The nasal sprays will be administered 50 mins prior to the functional magnetic resonance (fMRI) protocol using a standard supervised dosage procedure that involves 3 sprays in each the left or right nostril (6 sprays total). The fMRI protocol will be 20mins in duration and involve showing participants a brief task involving pictures of human faces expressing different emotions. The MRI protocol will also involve taking structural, resting state images of the brain while the participant is not engaged in a task.
Intervention code [1] 292451 0
Treatment: Drugs
Comparator / control treatment
Placebo, a saline solution without the active (peptide) ingredient.
Young healthy adults (aged 18-39 years) will be compared to healthy older adults (60+ years)
Control group
Placebo

Outcomes
Primary outcome [1] 295694 0
Functional MRI (fMRI) data will be collected in response to an emotional face expression task. The fMRI data will be compared between the older and younger age groups for differences in brain response (e.g., in the amygdala) between placebo and oxytocin conditions.
Timepoint [1] 295694 0
The data will be collected in the 50-80 min post drug administration and will be analysed post all data collection.
Secondary outcome [1] 316243 0
Using the structural MRI data, the whole-brain structural differences n grey and white matter will be examined comparing the participants in the older and younger age groups to see if any structural brain differences are present.
Timepoint [1] 316243 0
The data will be collected in the 50-80 min post drug administration and will be analysed post all data collection.
