Abstract: The science to explain the mode of operation of the brain, such as a series of perception, habits, hypnosis, language, learning and other topics are given insights, especially the brain's unconscious logic of this issue.
Unconscious system
Unconscious identification system is responsible for forecasting, perception of stitching together the pieces. Consciously accept the result of the operation system unconscious, to review when necessary, and to develop strategies according to background information. (Thoughts: a priori unconscious conscious:? Posteriori)
1. Why do strange dream?
While awake, eyes, thalamus, visual pathways formed visual cortex. In sleep, the brain stem, thalamus, and visual cortex form a new visual pathway. During sleep the brain stem to replace the eye, become a source of material. If the visual cortex receives mixed signals, it tries to figure things out, using the knowledge and memory reserves, scattered signals will be linked together to form a complete story. That's the dream. Because during sleep, perform advanced decision-making functions of the prefrontal cortex will be completely silent, no reflection prefrontal thinking. So very strange dream.
Blind people, the visual pathway receives a signal to other sensory organs, as if you can see, this is why blind people can see what a dream.
2. Why are people driving on the road for something to turn a blind eye when the call?
This is because a conscious visual part ceased its activities in the time to concentrate on the call. Brain activity in a control involuntary eye unconscious process of taking over the visual system to guide us towards the destination, this example illustrates the awareness and vision can be separated .
The system used to speed faster than non-habit system. Rather than the customary system, you can think about the new environment, and thus regulate behavior.
Procedural memory from the outside of the striatum, is the region produced habits . Episodic memory is stored in the hippocampus, activating non-habit behavior. Not only can not be used to record information and convert it into episodic memory, the plot can not extract information from memory, so in the habit of driving home to take over time, will forget temporary task. (So the doctor advised us not to eat in front of the TV, as this can cause overeating)
3. unconscious conscious explanation vs
As long as there is a healthy brain, we will be able to expand the use of education to correct the stock of knowledge to adjust their beliefs to provide reliable information system for the unconscious to guide rational explanation made it real.
Mirror neurons
1. Why watch the action skilled athletes can increase your activity level?
Mental training, not only can improve athletic level, but also enhance the use of those muscles in the imagination.
This may be mirror neurons play a role, watching skilled athletes action can improve your activity level, watching the video, to see the complexity of the operation has been corresponding with the neural basis and start accurate simulations.
Why can yawn contagious? It is a similar reason.
Alzheimer's syndrome can not generate empathy.
Observe others, practical training and mental exercises, these methods can make the brain back to our unconscious system: 1 in motion, it can make us do not have to think about whom you can improve performance. 2. mirror neurons, which simulates we have witnessed the scene, so that we can learn from each other, express empathy. 3 mark by the body, which in turn draw on past experience to guide future decisions.
Learning and memory
The same impulse is sent to the same neuron twice, this will enhance the response of neurons, like neurons remember had received information like this.
Two or more simultaneous activation of neurons, will create a link between these neurons. They will stimulate an additional receptor, a stronger synapses. This strengthening of synaptic connections called long-term potentiation memory, which is the basis of memory formation.
Our memories define us, for any moment, they are recorded, meaning we had feelings, emotions, and that moment for us outside of the event. Many of our experience, will be included with the feelings of the body, which is the body tag, such as related to food, places, taste the emotional response will then meet again triggered a similar environment.
The human brain will be a self-protective way to organize our history snapshots. We will quickly forget the negative emotions associated with those memories. The system will create between unconscious in our lives in a snapshot contact, monitor our emotions all the time, decide what needs to be emphasized, which need to be removed, will these snapshots' are combined into a story.
Illusion and the ultra-religious experience
1. Brain Science illusion explained
Precise stimulation of the temporal lobe can create the perception of a foreign body in the surrounding. Brain need an explanation for this strange feeling, there have been many supernatural phenomena, as well as ultra-religious behavior.
在生死关头战斗机驾驶员身上会出现一些濒死体验。
2. 人是怎么区别自己即将发出的信号？自己挠痒和被别人挠痒的区别
象鼻鱼的脑部发出一个指挥信号命令身体发电，他也同时会将这个信号的拷贝，但是上下颠倒的信号，发送到探测电场的感觉系统，这个拷贝通知感觉系统脑部刚刚发出一个指挥信号，所以指挥信号接受到一模一样的命令，但是方向相反，所以就忽略了这个型号。
