  《人脑漫游》是一部由Sam Starbuck执导,Susan Greenfiled主演的一部纪录片类型的电影,文章吧小编精心整理的一些观众的影评,希望对大家能有帮助。

  《人脑漫游》影评(一):A Brain Story

EP01
Feeling have a body: a body image/map
  e. a phantom limbs 幻想肢: still has a touch feeling; touch face →a feeling in hand
Thinking&character
  e.lose the ability to recognize music, always like the first time to listen, But language still works: where is the music center? Not a single area.
PK
  PK cured by dopamine, not effective
MEG: measure magnitude
Individual personality&creativity &religion
  e1.Dick:a patient with the front of brain disease, cells’ death:
1)a different individuals,less compassionate
2)a new skill to draw
  e2.Van Gogh: epilepsy
Temporal disturbance → visual perception
                       religious belief “I am the holy spirit”
  e3.Temporal epilepsy :
     1)colors are brighter. Love the scene when elevator up and down, the red and green button looks good
     2)Religious illusion
How the brain generate the religion :Experiment
     stimulate temporal lobe → visual experience
     modify the magnitude → other sensations
     B no clear religious experience
EP02 In the heat of moment
Facial expression
e.no difference between modern people & people in tribe
basic emotions :happy, sad, sick, surprising, angry, fear
sickness
  e.the research of sickness
    1)14months baby has no sickness to food ,but 3 years have the sense of sickness just according to the food’s appearance.
    2)3-4 not sick of polluted juice, but 7 years boy refuses.
    3)sickness about abstract things.
  The MRI result about sickness→前脑岛,关于腹部恶心
fear
  e.the patient having the experience of being at war
2 separate ways: 扁桃体(fast)&皮质(slow)
related to memory: hippocampus.
持续恐惧改变了他的大脑结构【连一把胡志明市的碎土都足以让他落泪】
The effects of past emotion
We are shaped by our personal history.
  e.the role of emotion when decision making
    no rules can be understood by logic, so the decision are made with the results of past emotion and the experience.
love
  e.催产素:哺乳、生产&高潮;大脑边缘系统【传说中的慰安妇用品】
its amount is related the degree of feeling about love
no relationship with drugs
  e.other drugs? as a tool to stimulate the edge system.No.
安非他命兴奋剂,一半以为服用兴奋剂,另一半以为是安慰剂 → different reactions because of their motion → so, no relationship
EP03 The eyes of mind
Separate visual areas and functions
  e1.stroke: no vision of objects in motion, ”a frozen world.”
    smaller regions(30+)color,shape, even depth and the orientation of tips.
  e2.an ingenious illusion experiment : 一根已经接触过的木棒,看起来很长,捏着两端拿起的时候会相差一些距离。(比如看起来球很小但一只手拿不过来。这是视觉区域独立地支配?)
a way to recognize, another way to control moving, separately.
Specific “blind”
  e1. face blind, faces are not the same, but they not look like any face.
recognizing faces need the look of totality of the face. An independent system, specialized and elaborate,
  e2.not know the whole, only see the details
inability to contact the sight with the knowledge
Attention system
  e1.change blindness experiment 被试填表,交表和还表的时候换人,75%被试没有注意到
  e2.Injury(stroke) in right side of brain → neglect one side, but can be reminded
1)eyes are slaves of attention.
2)imagination repair the neglecting, so they think the object is complete
Imagination effects on vision
     vision is not one side way, but also receive information of memory, knowledge and imagination
  e.although recognition being destroyed, can recognize by previous memory and knowledge (can draw or describe but can not recognize)
  1)visual perception and mental images are not same
  2)but no apparent contact having been found between forward and back area
An amazing idea :Vision is just a kind of dreaming, brain makes images and project out.
Vision not rebuild, but create a world.
EP04 first among equals
The frontal lobe function: plan, social, and so on
  e1.a soldier with hurt in the frontal lobe lose his aim and the ability to predict the result.【他的婚姻史简直随便得像美国赃小说】
  e2.judge with/without thinking: a small region excited
  e3.in mazes, chimpanzees perform better than human with the active frontal lobe and they can plan ahead of several days.
Language, passing on experience
  e1.language disorder, the patient tries to make sense with no-language clues,such as expressions.【失语症。也就是忘记词语的人。】
Wernicke’s area is about language, but not related to the understanding of language.There is another area about the complex function.
  e2.a direct way to study: stimulate each area of a wake patient’s brain
A web of language sites:
1)a variance among people
2)different words in different areas, such as “fruits area”
  e3.chimpanzees can learn meanings of signals,even the order of words (seems understand the sentence). Their comprehension compares as a 5-7y child.
Hemisphere specialized→不对称是人类发达的关键,而非脑容量。
  e1.when chimpanzees/human match words and signals, human left hemisphere active, but chimpanzee both active. 给猩猩涂满花生酱的管子,长时间观察发现它们越来越倾向用右手.
  e2.separated hemisphere, IQ higher in the left, but vision weaker than the right.
A theory: To develop the language skills, more cortex are used ,which decreased the perception function in the left. The right hemisphere is an evolutionary relic.
Evolution of creativity and imagination
  e.Neanderthals owns technique skills but no imagination.”they may know the word daughter and flower, but can not say ‘my daughter is like a flower.’ ”
EP05 Growing the Mind
distinguish face
  e. 8 months baby, not same brain activity for a up side down face. So the experience works.
  Experience → dynamic flexible brain
  e.非抽搐性癫痫Harrison, a surgery to cut his left hemisphere. The brian rewires in children.
Grey matter shaped by experience in adult, flexibility is vitrual for learning.
  e. reading difficult. New connnetctions forms when letters are changed into words.
Memory
  e1. A baby can recognize mother’s voice.
  More domains and faster respond are involved when there is sth familliar
  Why we lose early infant memory: erasing or losing the key to unlock the location.
  e2. A mini event offers chance to remember (eg.name+face+...) But John with a damaged hippocampus can not, which means that he lost the ability to bring together fragments.他永远只有一时的体验,而没有充满感情的回忆。人生如同分离的事实,无可参与。【真正的局外人】
  e3. Semantic dementia patients can not distinguish.
  Semantic memory is the memory of facts,
  e4. Walking-thinking. Old ones utilize more recongnizing resourse to walk.
  Old wisdom comes from a better selective way. Their world become a smaller part.
  A personalized brain = mind.
EP 06 The final mystery : Consciousness
Not only one center
  The switch of consciousness among different things based on only a center?
  e.visual cortex damage causes blind, but not the lose of consciousness. Frontal lobe also involved.
How to become a center
  “神经的涟漪”
  e1. Anaesthesia has gradual stage, which means the gradual loss of consciousness.
  e2. Ketomene bring illusions and distorted experiences【He travelled the galaxy. 好想试!】
  e3. A circus bear their pains to perform.
Unconsciousness
  e1. unconscious reflex
  e2. 2s delay before consciousness
  Sub-consciousness helps us, even determines the consciousness.
  自由意志真的存在?做出决定那一刻之前,脑已经做好准备。我们并不受控于所谓的【自我】和【意识】We are organic machines.
Free will
  e1. Joe has spilt brain.
  Left hemisphere gives us the illusion of free wll.【有一种错觉叫自由意志】
  Consciousness: physical reality, not based on centers but a whole situation.
“I don’t believe neuronsci will ever undermine what it feels like to be a unique individual human being.”
 
I wanna research or be researched...
    

  《人脑漫游》影评(二):我们究竟对人脑了解多少?

2016年第7个纪录片节点之《BBC:人脑漫游》,这一主题最后的部分当然就是大脑了,也是最为神秘和复杂的人体器官,至今令人难以捉摸。你之所以是你,而不是别人,就取决于你的大脑。本片带你深入活生生的人类大脑,通过一系列脑部损伤的病患案例来一探大脑的奥秘,看看脑部是怎样的一部复杂精密的机器,我们头脑中独有的那些记忆、情绪以及思想全都是数以兆计的脑细胞相互合作产生的,才有了无与伦比的心灵生活。这其中不得不特别提到梵高的病例,颞叶性癫痫使梵高的大脑不受控制,而这可能永远地改变了他看世界的角度,他真的是因为脑部疾病缔造出惊人的创造力么?

  《人脑漫游》影评(三):意识之谜

06:最终的谜团
1、为了测试安眠药的效果,当病人正在经历大手术时(已经可以看到心脏),医生询问迷迷糊糊的患者:“你感到舒服吗?”
2、从直觉上,我们感觉自由意志在支配我们的活动。然而科学家们发现,这未必是事实。在我们的自由意志作出决策之前的半秒钟内,我们的下意识已经开始活动了,我们的自由意志只是下意识的结果。
3、有个自虐马戏团,专门表演一些看起来很痛的活动。一个是人体镖靶:一位男性表演者裸露后背作为镖靶,另一位女性依次扔出飞镖,一共有3个,都扎在了那位男性后背的肩胛骨下方。这位勇敢的男士解释说,他会对即将到来的疼痛做好准备,同时会想象自己泡在温水中,以分散注意力。然而,对于无准备的疼痛,例如突然踢到障碍物,他和常人感受到的疼痛程度是一样的。
另一位男士将脸埋在碎玻璃上,然后让女嘉宾(一位女科学家)踩在他的后背上。
最后一位男士更加生猛。他的左右耳垂各挂着一个熨斗;舌头中间打了洞,中间穿了绳子,下面挂着一个蓄电池;另外,两个乳头下面也挂着重物。只见他双手各拿着一个熨斗,同时抛到后背上,两个耳垂迅速被硬扯了一下。此刻,观众们有的在喝彩,有的感同身受,表情很痛苦。这时,这位表演者慢慢站起来,舌头拉着蓄电池离开了下面的支撑物。接着,两个乳头悬挂的重物也离开地面了。。。

  《人脑漫游》影评(四):记录

1:
【特定部分负责特定功能】讲话时此区域有物理运动。
【人体地图】脑中特定区域感知人体各部分➡️幻肢的存在。
【脑中多部分的协作来决定某种能力】音乐鉴赏能力。
【化学物质可影响大脑运作】多巴胺可以让帕金森患者受损的神经元活跃起来。
【前额叶跟个性相关】受损者性情大变。
某部分受损可刺激其他部分生长:病人新增创造力。
【颞叶(太阳穴后)主管视觉和听力】受损(癫痫)会视觉感受更鲜明(梵高的强烈色彩和轮廓)/ 受损会引起宗教感受(灵魂出窍等)
b.神经元的活动以及互动式形成我们思维行为的根本 c.当各部分功能失衡的时候,会让我们性格变化或者才华体现。
2:人类的表情是共通的/ 我们是理智和欲望的结合体 / 人类有恶心中枢和恐惧中枢

  《人脑漫游》影评(五):人脑更出色

01:尽在脑中寻
脑的损伤可能带来意外的艺术才能。有的普通人在脑部创伤后,虽然性情大变,但却喜欢上了绘画。他们之前并不喜欢画东西,如今却有着独特的视角,强大的创作激情,以及令人耳目一新的创作成果。梵高得了癫痫,之后又得了抑郁症,或许他的艺术才能也得益于头脑的不正常运作。
一些儿童能够绘制出具有幼儿风格的画面,而很多成年人却画得毫无美感。在我看来,这些儿童正是得益于脑部还没有发育成熟。
02:情感澎湃
1、1岁左右的儿童不知道什么东西是令人恶心的,什么都放到嘴里尝试。3岁以上的儿童看到大便和蟑螂会觉得恶心,他们拒绝吃看起来像大便一样的东西,或者喝放了蟑螂的饮料。但是如果把蟑螂取出,3岁左右的儿童会喝饮料,他们对饮料已被污染没有概念。相反,7岁以上的儿童拒绝喝这种已被污染的饮料。另外,成年人对纳粹的标志会感到恶心,说明他们恶心的范围更广了。
2、在一次实验中,有四个人服用了安非他命(苯丙胺),也就是一种可以令人兴奋的毒品。其中两个人被告知他们服用了安非他命,另外两个人却没有被告知。半小时后,当毒品发挥作用时,被告知真相的人感到特别兴奋,心情愉快,他们认为这就是毒品的正常结果,所以欣然接受。相反,不知真相的人却感到烦躁,他们不清楚自己为什么变得和平时不一样。
03:思想之窗
1、通过透视引起的错觉,两根长度一样的小铁棍,看起来却不一样长。这种奇怪的现象现在我们已经很熟悉了。神奇的是,虽然看起来不一样长,但是当我们打算拿起它们时,食指和拇指张开的距离竟然是一样的。换句话说,我们指挥手部运动的大脑区域和处理视觉信息的区域并不完全一致,互相之间并不影响。
2、我们知道有的人脸盲,也就是无法辨认别人的面孔。有趣的是,还有一个人虽然能够辨认面孔,却无法识别物体。他经历车祸后,就认不来东西了,例如一把刷子。他头脑中知道刷子,但就是认不出来。有趣的是,他能画出刷子,但是过一会重新把他的画给他,他竟然不认识自己画的刷子了。另外,还有的中风患者不能够看到物体的运动。
3、有位中风患者只能注意右手边的物体。让她临摹一只猫,结果她只画出了右手边的半只猫。在科学家的提醒下,她才发现自己没有画左边的部分。但是如果你直接给她半只猫的画面,她能发现是半只猫,只是她在画东西时,注意力只能集中在右半边。
04:万物之首
1、黑猩猩也会玩迷宫游戏,而且能够比人更快走出迷宫,说明它们有计划能力。它们能够做几天的计划,甚至更长的计划。然而,人却可以做几年甚至几个世纪的计划。
2、切断胼胝体,也就是左脑和右脑之间的连接,就形成了裂脑。这样一来,左脑和右脑就失去了联系。有趣的是,裂脑症患者擅长左右手独立执行工作,例如一只手画方形,另一只手同时画圆形。而我们知道,正常人很难完成这样的工作。
3、古猿人在长达10万年里一直制造和使用手斧,也就是一种可以用来切削肉的石片。令人惊讶的是,它们在如此长的时间里竟然没有改进工具。科学家猜测,也许在这段时期内,他们的语言也同样停滞不前。
05:思想培训
1、一位得了老年痴呆的老人,丧失了很多记忆。他看展示动物的卡片时,无论看到的是猎豹还是老鼠,都将它们说成是猫或是狗。对于动物,他只记得猫和狗。
2、老年人能够同时处理的信息比较少。在走复杂的路面,例如有很多障碍物时,他们就需要专心走路,而不能边走边说。边走边记忆听到到的单词,这对老年人也很困难,但是年轻人却更容易做到。

  《人脑漫游》影评(六):只能是在漫游

     他们相信一切思想个性行为意识都是实体。如果小学时就看了这部,会对之后的我产生怎样的影响?不知道在这过去的16年间又有了怎样的新研究进展。
     “我们对大脑的理解程度,就好像从腾云驾雾的飞机上俯瞰城市,我们看得见哪里是工业区、住宅区,哪里是机场或当地的主要交通干道、郊区从何延申,我们也知道城市的个别单位(即市民,在此比喻神经元)长什么模样,可是大致来说我们无法知道这些人饿了会去哪里,怎样维持生计,或某个人日常的通勤路线,大脑产生意义的方式忽近忽远、难以捉摸,这中间的内容——思考和记忆、大脑的语言,至今仍是深不可测的谜。”
