"Born blind people, the dream will have color?" February 5, Yan Gongzi on the microblogging case asked.
This is both scientific and emotional questions. The simple answer is, no. The brain can only use the material known to weave a dream. And when we "watch", with more than just the eyes, but also the brain. All we can "see", in fact, is based on previous experience and looking forward to seeing things. Whether awake or dreaming, this will not change.
The researchers had surveyed 15 372 blind people dream, concluded that the age of five blind dream no color, basically there is no visual image. After only seven blind people dream made little difference with the ordinary people, but as time goes by, the dream "see" things may be less and less, more and more blurred. Five to seven blind between the two possibilities in there.
Born eyeless radio host Tommy Edison (Tommy Edison) has answered on youtube, listening to his dreams only taste four olfactory sense of touch, but he will also experience a dream to various illogical plot unfolding of God , Jumper situation instantaneous transformation. ? Long illness aged blind and deaf Helen Keller (Keller Helen) has written such a dream: She hid many people anxiously looking for her, came up with a lot of movement - know this because she feet felt the shock came - and then she suddenly felt cold and frightened, the wind floated the smell of ice and salt, she tried to escape, but was tripped long grass, and then she lay there, motionless, and as grass blade, cut her finger ...... she has a recurring nightmare, a Ghost whistling through her face, in her feeling inside, it was like the engine while blowing hot air, she I guess this nightmare from childhood risk being burned experience.
Carefully read will find Helen in reality do not have the vision and hearing, in fact, did not appear in a dream, her brain early loss of both senses, that never lost understanding "audiovisual" capability. In addition, those who are born color-blind, I can not dream of color own reality not visible. In comparison, a 52-year-old was due to blind people with diabetes in the United States Foundation for the Blind website commented that he was still doing the colorful dream, in a dream, he could see, as in the past. And although later color television promotion, a substantial increase in the proportion of the color of dreams, but there are still about 17 percent of normal vision only dream in black and white, for reasons that remain unknown.
Unless a stroke or traumatic brain injury caused by a particular remaining everyone dreaming. It was a dream reluctantly, it was thrilling dream, it was a dream limit unfathomable dream ...... although both may occur in each sleep period, but mainly focused on the "rapid eye movement (REM)" stage, this stage people wake-up, in all likelihood be able to remember some of the dream fragments. Many warm-blooded animals have this paradoxical sleep, such as birds and terrestrial mammals fluffy. However, the pursuit of dreams of animals, so far only Homo sapiens.
Like a dream come to life in a parallel world, he watched the scenes unfold situation. Then we wake up in reality, I think hard to remember some of the twists and turns of the magnificent fragment. Dreams are often difficult to understand, so people after their brains appeared to various interpretations. The ancients often the dream as a divine revelation or prophecy, then the dream Freud regarded subconscious desire to meet the wishes, of course, he also found it difficult to justify some of the nightmare, the dream began to root out all kinds of "sex" related symbol.
Today, scholars believe that in the "dream is to meet the psychological needs," Pink Floyd is running. Dream is considered dominant when internal information, the result will cerebral cortex is difficult to control and rationalize the various fragmented information input. AIM theory Harvard Hobson (J.Allen Hobson) submitted deeply affected "dream community." A represents activation (activation), representative of the flow of information from inside and outside (information flow), M represents an information processing mode (mode of information processing). The so-called sober, that is, three AIM taste, highly activated brain, smooth inflow of external information, information processing speed operation. Dreamless deep sleep, is AIM three are quite low. The dream, then there is A there is no M I, in many regions of the brain remains highly active, but the external flow of information at a much stagnant, so active brain had started on the edge of a material made out a coherent story.
In the dream, the retina and primary visual cortex are suppressed, and higher order storage analysis as the parahippocampal cortex cortex is actively self-sufficiency, to extract information from past experience, creating a variety of visual images. The same active brain area also includes the emotional charge of the limbic system (such as the amygdala), so many dreams with strong negative emotions, especially anxiety and fear.
Unless it is lucid dreaming, dream or particular stimulus, or else in charge of logical reasoning and working memory in the prefrontal cortex in the dream often suppressed. This is why no matter how extravagant dream, we are difficult to see the flaws in a dream, wake up often forget just dream of doing. Only in extremely rare "lucid dreaming (lucid dream)", the dreamer responsible for reasoning dorsal anterolateral prefrontal very active, which can perceive dreams in place of the illogical, even as "Inception" general control Dreams Trend.
In the dream, the motor cortex can produce electrical pulse command, but because of the cholinergic signal to trigger the inhibitory loop, causing these instructions can only reach the upper end of the spinal cord, muscle contraction can not reach the control effectors, in a sense, a dream who is in a paraplegic state, which is the "ghost press" principle - if you perceive to be awakened, but the motor cortex cortical instruction is not smooth, you'll find yourself unable to move.
Inhibition of brain damage in case of loops, the dreamer may make all kinds of action. Fifty years ago, the French researcher Michel? Jewitt (Michel Jouvet) to take the cat done experiments and found that after the pons in the locus coeruleus (Locus Coeruleus) damage, cat in a dream will make hunting avoid such action.
Similarly, changing a person's brain can affect his dream. Antidepressants alter the neurotransmitters in the brain, taking sometimes do more dreams. Some researchers dream of being the person administering transcranial magnetic stimulation, successfully weakened his experience in a dream sense SOUL ...... one day, "Inception" and even "implanted in a dream idea" is not necessarily can not be achieved. By manipulating dreams, we might be able to spend more enjoyable every night for two hours.
