Task (EG1)
  1. RF EMF Exposure: (ps) SAR: (peak spatial) specific absorption rate; L: left side exposure; R: right side exposure; L+R: left and right side exposure; T: exposure of top of head; GSM: Global System for Mobile Communications
  2. Experimental Design: EG: Experimental group; CG: Control group; M: males; F: females; Handedness: R: right handed, L: left handed; SB: single blind; DB: double blind
  3. Cognitive Tasks: No: number of tasks applied; B: task applied before exposure; D: task applied during exposure; A: task applied after exposure; RT: reaction times
  4. Results: ↑: significant increase; ↓: significant decrease; n.s.: no significant effect (compared to sham)
  5. : accomplished; - not accomplished/specified
