Primary Outcome Measures

Name	Time	Method
Neural Activation	Baseline Scan (Day 0) and and Follow-up Scan (From day 29 up to 4 weeks later, depending on the Scan scheduling availability)	As measured for example by Fractional amplitude of low-frequency fluctuation (fALFF) signal, assessed using functional Magnetic Resonance Imaging (fMRI).

Secondary Outcome Measures

Name	Time	Method
Respiratory Rate	Daily from Baseline (Day 0) to a day prior to Endpoint (Day 28)	Daily respiratory rate (RR) will be collected by WHOOP Strap 2.0, a wearable photoplethysmography (PPG) wrist sensor.
Heart Rate Variability	Immediate: Baseline Scan (Day 0) and Follow-up Scan (From day 29 up to 4 weeks later, depending on the Scan scheduling availability); Daily: from Baseline (Day 0) to a day prior to Endpoint (Day 28)	Heart rate variability (HRV) will be measured in two modalities. Immediate continuous HRV, collected during resting-state MRI scans, will be measured by a wearable photoplethysmography (PPG) finger sensor. Daily HRV over the 28-day training period (RMSSD) will be collected by WHOOP Strap 2.0, a wearable PPG wrist sensor.
State Anxiety scale score	Immediate: Baseline Scan (Day 0) and Follow-up Scan (from day 29 up to 4 weeks later, depending on the Scan scheduling availability); Daily: from Baseline (Day 0) to a day prior to Endpoint (Day 28)	The State-Trait Anxiety Inventory (STAI) is an instrument for measuring anxiety in adults. It has 2 scales: State Anxiety (S-Anxiety) and Trait Anxiety (T-Anxiety). The S-Anxiety scale measures anxiety due to temporary conditions, and the T-Anxiety measures anxiety on a general or more long-standing scale. The S-Anxiety is a 20-item scale; each item yields a score of 1 to 4. Scores on the STAI S-Anxiety scale increase in response to physical danger and psychological stress and decrease as a result of relaxation training.
