Article Title: Temporal order of activations and interactions during arithmetic calculations measured by intracranial electrophysiological recordings in the human brain

Figure Lengend Snippet: The first five rows represent examples of the task, where trials consisted of sequentially presented equations with the same general structure (bottom row). First, a fixation cross (a star) appeared for 1.0–1.5 s (randomly varied), followed by the first operand - number (N1), first operator (O1), second operand (N2), second operator (O2), third operand (N3), equals sign (O3), and a proposed result (N4). Subjects were asked to answer whether the result was true or false by pressing a corresponding coloured button on a gamepad (red = false result; green = true result; blue = uncertain). Feedback was provided based on their answer. Equations were either difficult (N1 was a double digit, result was over ten, only Arabic numerals; presented on the top row) or easy (single Arabic digits, words or symbols, from 0–9, result never exceeded ten).

Article Snippet: The participants’ goal was to determine whether the result was true or false and press a corresponding button on the gamepad (Logitech F310): green or red button for a true or false answer, respectively.

The impact of childhood trauma on peak subjective distress and stress reactivity during experiments was amplified by higher psychosis liability..

Article Snippet: Counotte et al., 2017 [ ] Netherlands , Cross-sectional, between-subjects , 44 ROP (M27, male 79.5%), 17 UHR (M22, male 41.2%), 37 SPP (M27, male 59.5%), and 45 HC (M 24, male 46.7%); N = 170 (143 HR available) , Vizard software (CleVR), Logitech F310 Gamepad, Sony HMD headset model HMZ-T1, 1280 × 720, 51.6 FOV, and a 3DOF tracker , Virtual bar with 3 stressors (avatar density/ethnic density/hostility): (1) No stress (6 avatars, >80% Dutch, neutral expression); (2) 40 avatars; (3) 40 majority non-self ethnicity; (4) 40 angry/hostile expression; (5) 3 stressors. , 1 (exposed to VR-induced social stress in 5 settings lasting 4 min each) , Before and after/during VR task: SSQ, HR, SCL , Heart rate, HF, LF/HF, and skin conductance level were all significantly impacted by the quantity of virtual social stressors in all groups. Instead of higher autonomic responsiveness to social stresses, psychosis liability was associated with lower parasympathetic activity in virtual social contexts, which implies generally high levels of arousal..
