In the digital age, our brains have been changed.

From the article "Our brains have been changed in the digital age", you will find that the digital age has brought great changes to our lives. The following is the reading topic and its reference answers of "Our brains have been changed in the digital age" that I collected for you to learn.

Our brains have been changed in the digital age

① We know that the human brain is plastic, and it may also change when the human lifestyle changes. Since ancient humans first discovered how to use tools, the human brain has been rapidly and obviously influenced. In the digital age, great changes have taken place in our lifestyle. When we can't live without the internet and mobile phones every day, has our brain been changed?

② Scientists believe that the deep dependence on network technology has changed the way of thinking of human beings. This is most obvious when reading. Deep reading of books is different from shallow reading for information on the web. American technical expert Nicholas? Karl wrote in the book "The Internet also has a dark side":? In the past few years, I have always had an uncomfortable feeling that someone or something is changing my brain. My current way of thinking is completely different from the past, and I can feel this most strongly when I read. Reading a book or a long article for a long time used to be a piece of cake. I once spent hours wandering in long words, and my brain was able to grasp the evolution of narrative or the turning point of argument, so as to think. But this is no longer the case now. My attention often drifts after reading two or three pages. I feel that I have been trying to drag my wayward brain back to the book. ?

③ deep reading of books requires patience, while digital reading is called? Patience killer? . Take Weibo as an example. It only takes a few minutes to browse a Weibo page, and the eye stays on each Weibo for only a few seconds. Constantly scanning, browsing, searching for interesting keywords, and clicking to read? This process is exciting enough because of the richness and diversity of information, but it is obviously not enough to exercise patience. An excellent book usually has an internal logical framework, and only by entering this logical framework can it be said to be reading. However, online content, especially social media such as Weibo, is not related to each other, so jumping reading is certainly not logical. The internet not only provides people with a feast of information, but also makes our thinking? Fragmentation? .

④ In the digital age, the human brain structure has also been changed. As the Internet and smart phones have penetrated into daily life, people have a special liking for touch screens. Some people are dubbed "because they frequently knock on their smartphones"? Thumb clan? . However, it is such a seemingly simple repetitive movement that is constantly shaping people's brains. In an experiment, neuroscientists at the University of Zurich in Switzerland invited 37 heavy users of mobile phones to participate in the experiment, 26 of them used smart touch-screen phones and 11 used ordinary touch-button phones. They connected electrodes to the heads of these participants and tested the responses of their thumbs, index fingers and middle fingers to the cerebral cortex when using mobile phones. Scientists recorded the activities of these participants for 1 days. The results show that the activity of thumb control related areas in the cerebral cortex is higher in people who use touch-screen mobile phones, but there is no significant change in those who use touch-button mobile phones. The more times you use a touch-screen mobile phone, the more active the corresponding areas of the cerebral cortex are. Growing up in the digital age? Digital aborigines? Because of using the thumb to surf the Internet and control the smart phone for a long time, it has changed the way the brain forms neural pathways.

⑤ In the digital age, people are better at using social networks to communicate with people, but their ability to communicate with people in real life is getting weaker and weaker. Modern diseases such as ADHD, autism, depression, restlessness and multitasking addiction are closely related to excessive internet access and video games.

The ocean is the cradle of life on earth and an important space for human survival and sustainable development. Building a digital ocean is to make full use of high-tech means to effectively obtain and use information and realize marine informatization. In the eyes of scientists, the digital ocean is to build a virtual ocean world by observing the ocean in a three-dimensional, networked and continuous way and obtaining massive data. It can turn the data of marine chemistry, biology, physics and other elements into an effective tool for human beings to use and protect the ocean; And by learning the direct expression of the current ocean landscape and the prediction and preview of the future ocean scene, the way of human development and utilization of the ocean is more reasonable.

the construction of digital ocean consists of three levels: first, three-dimensional real-time and continuous data collection. Three-dimensional observation of the ocean includes space observation, that is, all kinds of new remote sensing technologies are used to comprehensively observe the ocean characteristics at sea surface and within a certain depth below the sea surface, and sea surface observation means that the ocean is observed all-weather by the sea surface observation network; Submarine observation, that is, a submarine observation network composed of intelligent terminals such as submarine working platform, collects all kinds of marine element data in the depths of the ocean accurately and continuously. Modern network technology and energy technology enable this stereoscopic observation to continue for a long time. The second is information grid integration. Through grid technology, digital ocean cooperates with data collection, integrated information processing and unified operation calculation, so that all resources on the network can work together, thus completing all kinds of complex calculations in marine activities that cannot be completed by traditional methods, establishing various powerful application and decision-making models, and realizing in-depth and accurate understanding of the ocean. The third is the comprehensive application of knowledge. Different users have different needs and applications for marine information. To build a complete digital ocean system, we must build a basic ocean information service platform with strong publicity, wide comprehensiveness and complete functions and a comprehensive application platform for product development on the platform of massive information integration, and realize the ideal goal of one-time collection, sub-integration, unified development and utilization of ocean information according to the principle of rational development and utilization of resources. Different users can not only obtain their own professional information, but also carry out secondary development of relevant information according to their own needs.

The construction of digital ocean has brought a revolution in human understanding, management and development of the ocean. First of all, the ocean is a complex whole, and people's understanding of the ocean is limited and lagging behind only by traditional methods such as ocean observation stations, and they lack understanding of the process of ocean change. The three-dimensional real-time and continuous data collection of digital ocean and the integration of information grid enable scientists to actually master the process of ocean change and realize a qualitative leap in human understanding of the ocean. Secondly, modern marine management includes marine rights and interests, marine resources and marine environment. The application of digital ocean can realize the informationization, networking and intelligence of ocean management. For example, the real-time stereoscopic observation system of Louzi Ocean can monitor the sea area in the exclusive economic zone within 2 nautical miles of China's coast in real time, and any marine activities that violate China's laws will be reflected to China's maritime surveillance command center in the first time, so as to form a decision on safeguarding rights in time and ensure that the national maritime interests are not infringed. Finally, the ocean is the second territory on which human beings depend for survival, and marine development with the goal of acquiring and controlling resources has always been the key development strategy of coastal countries. Digital ocean has powerful information integration and comprehensive display functions, which can provide large-scale and accurate marine environmental data for specific marine development projects, and can be used to comprehensively evaluate the demand, benefit, cost and impact on surrounding waters of the project, so as to provide the best scheme for decision makers. This not only avoids the blindness of marine development, but also provides a guarantee for the sustainable development of the ocean. Reading topic of "Digital Ocean"
