"I Hate Video Games":从舆论到医学——美国精神病学会欲将游戏瘾列入精神病
对于绝大多数视频游戏玩家而言,游戏仅仅是游戏.它是一种以高科技手段来打发时间、尽情欢乐、在虚拟世界中一展身手的途径.然而,对于越来越多的超级游戏迷而言,则要严重得多--已经到了难以将现实和游戏分开的程度.

The current use of hearing aids and artificial cochleas for deaf-mute individuals depends on their auditory nerve. Skin-hearing technology, a patented system developed by our group, uses a cutaneous sensory nerve to substitute for the auditory nerve to help deaf-mutes to hear sound. This paper introduces a new solution, multi-channel-array skin-hearing technology, to solve the problem of speech discrimination. Based on the ifltering principle of hair cells, external voice sig-nals at different frequencies are converted to current signals at corresponding frequencies using electronic multi-channel bandpass ifltering technology. Different positions on the skin can be stimulated by the electrode array, allowing the perception and discrimination of external speech signals to be determined by the skin response to the current signals. Through voice frequen-cy analysis, the frequency range of the band-pass iflter can also be determined. These ifndings demonstrate that the sensory nerves in the skin can help to transfer the voice signal and to dis-tinguish the speech signal, suggesting that the skin sensory nerves are good candidates for the replacement of the auditory nerve in addressing deaf-mutes’ hearing problems. Scientiifc hearing experiments can be more safely performed on the skin. Compared with the artificial cochlea, multi-channel-array skin-hearing aids have lower operation risk in use, are cheaper and are more easily popularized.

嗓音医学中一些值得重视的新亮点
随着社会的进步和信息化水平的提高,人们的社会交往越来越频繁和广泛,对嗓音质量和语言表达的要求也越来越高.在西方发达国家嗓音医学已有50余年的历史,并有专门的言语病理专业和专业协会.我国嗓音医学目前还处于起步发展阶段,同发达国家相比还存在明显的差距,但发展迅速.根据我在国内外科研和临床工作的见闻,谈谈对嗓音医学中出现新亮点的认识和体会.
