(b) Experimental setup for concurrent tDCS-fMRI using the RF filter panel to transmit the current into the MR room. (c) Finger-Key Mappings for left and right hand. Top row shows original keyboard keys with number pads pasted on the those keys displayed in the second row. (d) Behavioral task timing diagram: Finger sequence task performed before and after tDCS, the sessions consisted of 5 epochs (E=Epoch of 30s) for each hand before and after the tDCS stimulation; the hand that performed the finger sequence task first was counterbalanced across participants. (e) Concurrent tDCS-fMRI timing diagram: 24 min of continuous rs-FMRI was recorded during which 10 min of tDCS was applied from minute 6 to minute 16. The rs-fMRI timing diagram shown in 1e was the same for the ASL and the BOLD experiment which were done in one session, but the order of the ASL or BOLD experiment was counterbalanced as to which one occurred as first or second experiment.

Article Title: Plasticity induction in the ventromedial prefrontal cortex during REM sleep improves fear extinction memory consolidation

doi: 10.1101/2025.03.31.646182

Figure Lengend Snippet: Experimental protocol. The experimental protocol spanned three days, beginning with the fear acquisition phase on Day 1. During this phase, participants learned to differentiate between two stimuli: a blue lamp (CS+), which was paired with an unconditioned stimulus (US), and a yellow lamp (CS-), which was not paired with the US. The acquisition phase lasted for 20 minutes. Between Day 1 and Day 2, participants were sleep-deprived. Approximately 24 hours after fear acquisition, they participated in fear extinction training. In this phase, the CS+ was no longer paired with the US, leading to extinction of the conditioned fear response. The extinction phase lasted for 10 minutes. After extinction training, participants were placed in bed and instructed to sleep, their sleep was monitored via polysomnography. tDCS or sham stimulation was applied during the second REM sleep cycle, and if necessary, during the third cycle, for a total duration of 15 minutes. Following the sleep phase, participants underwent the first recall session, which was identical to the extinction phase. On Day 3, approximately 24 hours after the extinction phase, the second recall session was conducted, following the same procedure as the extinction phase. Cortisol measurements were taken before each phase, and participants completed questionnaires after each phase.
