Subjects\nalternated between eyes-closed (EC) and eyes-open (EO) blocks of ~60 seconds\neach for approximately 16 minutes total.\nDemographics: Young adults (20-35 years, N=153) and older adults (59-77 years,\nN=74). All right-handed, normal or corrected-to-normal vision, no history of\nneurological or psychiatric disorders.\nRecording Setup\n---------------\n- Amplifier: BrainVision actiCHamp (Brain Products GmbH)\n- Channels: 62 EEG (standard 10-20 extended, ActiCAP)\n- Online reference: FCz\n- Ground: AFz (inferred from BrainVision convention)\n- Sampling rate: 2500 Hz\n- Impedance: < 5 kOhm (active electrodes)\n- Recording duration: ~16 min per subject\nTask\n----\nResting state with alternating eyes-open (EO) and eyes-closed (EC) blocks.\n- Eyes-open: fixate on LED (off state), eyes open\n- Eyes-closed: close eyes, fixate on LED (off state)\n- Block duration: ~60 seconds each\n- Event markers: S200 = eyes open onset, S210 = eyes closed onset\nKnown Issues\n------------\n- Subjects sub-010020, sub-010044, sub-010193, sub-010219 have incorrect .vhdr\n  file paths that were fixed during conversion\n- Subject sub-010203 has no marker file (.vmrk)\n- 5 subjects (sub-010235, sub-010237, sub-010259, sub-010281, sub-010293)\n  are absent from the dataset (not recorded)\nReference\n---------\nBabayan, A. et al.
