We investigated whether watching two-dimensional television (2DTV) or three-dimensional television (3DTV) resulted in differences in the brain’s processing of sensory information. We divided 25 participants into 2DTV (n = 13) and 3DTV (n = 12) groups. Participants watched 2DTV or 3DTV for 1, 2, or 3 h on different days. Before and at the end of each session, electroencephalography (EEG) was recorded for 10 min. The Simulation Sickness Questionnaire (SSQ) and the Visual Analog Scale (VAS) were used to assess general discomfort before and after watching. Each frequency band of the resting EEG was transformed into a standardized low-resolution electromagnetic tomographic (sLORETA) image. In the 2DTV group, 2 h of watching increased theta power in the central cortex and 3 h of watching increased beta power in the occipital cortex. In the 3DTV group, 3 h of watching increased delta power in the parahippocampal gyrus and middle frontal cortex. Theta power was significantly higher in the insular cortex after 3 h of 3DTV than after 3 h of 2DTV. SSQ scores were significantly higher after 1 h of 2DTV than after 1 h of 3DTV. Watching 2DTV vs. 3DTV triggered different time-dependent activity patterns. Watching 3DTV for 3 h increased slow-wave activity in the prefrontal cortex, while watching 2DTV increased fast-wave activity in the occipitoparietal cortex. Up to 2 h of 3DTV watching did not cause major changes in fatigue or EEG activity compared with 2DTV. Our findings promise to be useful in designing safety guidelines for watching 3DTV.

我们调查了观看二维电视（2DTV）或三维电视（3DTV）是否导致大脑对感觉信息的处理差异。我们将25位参与者分为2DTV（n = 13）和3DTV（n = 12）组。参与者在不同的日期观看1、2或3小时的2DTV或3DTV。在每次训练之前和结束时，记录10分钟的脑电图（EEG）。模拟疾病问卷（SSQ）和视觉模拟量表（VAS）用于评估观看前后的总体不适感。静息EEG的每个频带都转换为标准化的低分辨率电磁层析成像（sLORETA）图像。在2DTV组中，观看2小时会增加中央皮层的theta功率，而观看3小时会增加枕骨皮层的beta功率。在3DTV组中，观察3小时后，海马旁回和额中皮层的三角洲力量增加。3DTV 3小时后，岛状皮层中的Theta功率显着高于2DTV 3小时后。2DTV 1小时后SSQ得分显着高于3DTV 1小时后。观看2DTV与3DTV会触发不同的时间依赖性活动模式。观看3DTV 3小时可增加额叶前皮质的慢波活动，而观看2DTV可增加枕顶叶皮质的快波活动。与2DTV相比，观看2DTV长达2小时没有引起疲劳或脑电活动的重大变化。我们的发现有望为设计观看3DTV的安全指南提供帮助。3DTV 3小时后，岛状皮层中的Theta功率显着高于2DTV 3小时后。2DTV 1小时后SSQ得分显着高于3DTV 1小时后。观看2DTV与3DTV会触发不同的时间依赖性活动模式。观看3DTV 3小时可增加额叶前皮质的慢波活动，而观看2DTV可增加枕顶叶皮质的快波活动。与2DTV相比，观看2DTV长达2小时没有引起疲劳或脑电活动的重大变化。我们的发现有望为设计观看3DTV的安全指南提供帮助。3DTV 3小时后，岛状皮层中的Theta功率显着高于2DTV 3小时后。2DTV 1小时后SSQ得分显着高于3DTV 1小时后。观看2DTV与3DTV会触发不同的时间依赖性活动模式。观看3DTV 3小时可增加额叶前皮质的慢波活动，而观看2DTV可增加枕顶叶皮质的快波活动。与2DTV相比，观看2DTV长达2小时没有引起疲劳或脑电活动的重大变化。我们的发现有望为设计观看3DTV的安全指南提供帮助。观看3DTV 3小时可增加额叶前皮质的慢波活动，而观看2DTV可增加枕顶叶皮质的快波活动。与2DTV相比，观看2DTV长达2小时没有引起疲劳或脑电活动的重大变化。我们的发现有望为设计观看3DTV的安全指南提供帮助。观看3DTV 3小时可增加额叶前皮质的慢波活动，而观看2DTV可增加枕顶叶皮质的快波活动。与2DTV相比，观看2DTV长达2小时没有引起疲劳或脑电活动的重大变化。我们的发现有望为设计观看3DTV的安全指南提供帮助。
