齐鲁医学大脑未解之谜

1、 人类身体上的很多难解之谜存在于我们的大脑中。大脑是一个让人迷惑的器官，就像生和死、意识、睡眠和其他更多的东西，都是人类至今也没有解开的谜团。 梦境 睡觉 幻觉 意识 任务控制 记忆途径取悦大脑 死亡之谜 人体冷冻 天生与营养大脑十大未解之谜The brain ten big mystery 12021/7/27 星期二 人类身体上的很多难解之谜存在于我们的大脑中。大脑是一个让人迷惑的器官，就像生和死、意识、睡眠和其他更多的东西，都是人类至今也没有解开的谜团。 梦境 睡觉 幻觉 意识 任务控制 记忆途径取悦大脑 死亡之谜 人体冷冻 天生与营养大脑十大未解之谜The brain ten big

2、mystery 22021/7/27 星期二梦境 dreams 目前科学家还没有揭开这个谜底。一种可能是：做梦过程中通过刺激大脑分子间的信息神经键大脑进行锻炼。另一种理论是，人们梦到白天不能顾及的任务和情感，这个过程可以帮助人们巩固思想和记忆。一般而言，梦境会在浅睡时发生。At present, scientists have not yet opened the mystery. One may be: dreaming in the process by stimulating the information between the brain molecules of the brain

3、 to exercise nerve. Another theory is that people dream of tasks and emotions that cant be taken into account during the day. This process can help people to consolidate thoughts and memories. In general, dreams will occur when the light is asleep.32021/7/27 星期二睡觉sleep人的一生要花费四分之一的时间睡觉。然而，睡觉的根本原因仍然像天

4、马行空的梦境一样让人迷惑不解。长期失眠能导致精神恍惚、幻觉，并最终引起死亡。睡眠的两种状态深睡期(眼球活动减慢)，此时脑部代谢活动放慢；浅睡期(此时会做梦)，这一时期大脑活动活跃。某些科学家认为深睡期睡眠能让身体休息，保存精力，就像动物冬眠一样。Ones life will take 1/4 of the time to sleep. However, the fundamental reason is still sleeping like a powerful and unconstrained style dreams like people very much puzzled. Lon

5、g term insomnia can lead to trance, hallucinations, and ultimately cause death. Sleep of the two state - deep sleep (eye activity slowed), at this time the brain metabolic activity slowed; shallow sleep period (at this time will dream), this period of active brain activity. Some scientists think tha

6、t deep sleep can make the body rest, save energy, just as animals sleep. 42021/7/27 星期二幻觉hallucination是一种虚幻的表象，本来并不存在的某种事物，病人却感知它的存在。正常人偶尔也可出现幻觉，比如在焦虑地等待某人到来时，忽然听到敲门声，实际却没有人来。这种幻听的出现与期待的心理有密切关系，此外在受到突然强烈的刺激下亦可出现幻觉。正常人在殷切盼望、强烈期待、高度紧张情绪影响下，也可出现某种片断而瞬逝的幻觉，如一个母亲突然失去儿子，悲痛万分，有时幻听到儿子在同她讲话等等。这种幻觉往往持续时间不会太长，

7、随着心情的好转，适当的治疗，便会痊愈。Is a kind of illusory image, there is no one thing, the patient is aware of its existence. An occasional illusion, such as waiting for someone to come, suddenly heard a knock on the door, but no one came. There is a close relationship between the auditory and psychological expecta

In normal people anxious, strong expectations, highly intense emotional impact, also can appear some fragments and evanescent illusion, as a mother suddenly lost son, grief, sometimes heard talking with her son in magic and s

9、o on. This illusion is often not too long, with the mood for the better, the appropriate treatment will be cured.幻觉具有两个主要特点：第一、幻觉是一种感受，由于缺乏相应的现实刺激，所以客观检验结果证明这种感受是虚幻的，但就患者自身体验而言，却并不感到虚幻。第二，虽然幻觉源于主观体验，没有客观现实根源，但某些患者坚信其感受来自客观现实。The illusion has two main characteristics: first, the illusion is a kind of

10、 feeling, because of the lack of the corresponding real stimulation, so the objective test results prove that this feeling is illusory, but the patients own experience, but did not feel unreal. Second, although the illusion is derived from the subjective experience, there is no objective reality, bu

11、t some patients believe that their feelings from the objective reality.52021/7/27 星期二幻觉可分为真性幻觉、假性幻觉和残留性幻觉三类。真性幻觉时，大脑皮层感受区的自发性兴奋使以往映象活跃化而重现出来，此即表象。由于表象特别强烈，鲜明、生动、详尽而投射到外部客观世界。投射是指当表象活化的强度大到与现实刺激产生映象的同样程度时，在人的意识中就无法与现实刺激映象相区别，而是按照生活惯例习以为常地认为它是来自客观空间，所以这是一种自然而然的向外投射过程。Can be divided into true hallucina

15、s chirping, and even fresh air blowing your cheeks, you will feel a sense of happiness. In other words, you are conscious. The complexity of the topic from the beginning to haunt the scientific community. Recently, neuroscientists to consciousness as a realistic research topic.72021/7/27 星期二任务控制Task

19、life are unforgettable, but scientists have used brain imaging techniques to try to make it clear the mechanical reflection of creating and storing memories. The hippocampus, which is found in the gray matter of the brain, acts as a function of the memory storage box. But the ability to distinguish

20、the storage area is not strong. Stimulation of the same region of the brain can make it true and false memories. In order to get the real memory from a false memory, the researchers put forward according to the background of memory method to enhance memory, if something really happened, it is diffic

24、的一生中细胞不断受到损害从而引起人体老化。大量研究人员认为，科学将最终推迟变老速度，使人类寿命至少可以达到预期生命期限的两倍。Why do we grow old? Human aging is divided into two kinds of theories: (1) as other features of human beings, aging may be a part of human genetics, and in some ways beneficial to human beings. (2) to the most optimistic point of view, t

25、he old is not the intention of peoples life, the cells continue to be damaged to cause the bodys aging. A large number of researchers believe that science will eventually delay the aging of the speed, so that human life can be reached at least two times the expected life time.112021/7/27 星期二人体冷冻Huma

26、n frozen要求长命百岁可能并不现实。但是一个被称作人体冷冻学的新领域将会让某些人死而复生。在充满液态氮并且温度为华氏零下320度(78绝对温度)的刺骨的容器中储藏死者的遗体。这个想法的目的是，死于目前无法治愈的疾病的人在将来发现治愈方法后可以通过解冻让他们死而复生。Longevity requirements may not be realistic.

28、系，证明它可能是受其中之一控制或者是由两方面同时控制。研究个体基因的能力显示出我们对很多人类特性无法控制，然而在很多领域，同辈人面对的压力或接受的教育会对我们是什么样的人以及我们将做什么产生深远影响。Whether our thoughts and personality are controlled by genes or environmental issues has long been debated. Scientists have established a convincing system of evidence that it may be controlled by one

29、 of them or that it is controlled in two ways. The ability to study individual genes shows that we cannot control for many human characteristics, but in many areas, peers face pressure or education on what kind of person we are and what we do will have a profound impact.132021/7/27 星期二谢谢观赏Thank you!
