As there are phobias Bashny.Net

Phobia is a inadequate experience fear, covering a person in certain circumstances. Phobias are very many and they all occur with different frequency.

It is believed (and it seems that even this is checked in some manner in monkeys) that some phobias are primates and people are already predisposed from birth. There are studies where it was determined that children 6 months to react on the lookout for the silhouette of the snake.

And this innate predisposition explain that people often get scared of heights, spiders, snakes, enclosed spaces, dogs.

 



Other phobias are less common, despite the fact that in the modern world of the middle band spider, for example, often represents only a threat to flies and cleanliness in the house.

But still, what's with the brain?

And the brain happening here are.

All information that comes to us from the senses, it is not directly in the bark, and passes several large clusters of nerve cells. In particular the thalamus.The thalamus is the main relay station, and he distributes it where to move.

The information is stored in different places. The first and most reliable bark. There information is stored long-term. Short-term memory we have in gippokampe.

Just imagine that you see a spider. From the eyes of the impulse goes to the thalamus. From the thalamus to the visual cortex, where it is processed. Cora recognizes the spider and compares it with samples from long-term memory. And decides: "yeah, it's dangerous."

And the impulse is sent to the amygdala – the fear center,which mobilizes the body to respond to the threat.

But it's actually a very long time to save the life if the spider was really dangerous. Meditation is how seconds, for which in case of danger it will be too late to escape.

A little shorter run impulses to gippokampa. There is stored short-term information that the brain was regarded as a "seemingly significant", but the brain is still not sure, send it in long term memory or not.

How it works can understand how people after just suffering psychological trauma startled by sharp sounds, taking them for a repetition of the recent horror.

Hypocamp not very picky, and if there are matches (which may take quite a large scatter and to be a "coincidence" with a very big stretch),he immediately gives a signal to the amygdala to raise the alarm.

Then a large part of the stimuli will be transferred to the cortex for evaluation and rethinking, ocanada as non-hazardous and the person calms down.

However, this is still too long. Recently it became clear that the amygdala can store information, too. But she's even less subtle than hippocamp, and even in comparison with bark and especially. There is information about the physiological components of fear. Heart rate, blood pressure, muscle tone, releases stress hormones. So, the experiments showed that information from the thalamus in the case of a phobia is the right place.

I.e. this is the "brainstorming method" "to take a shortcut through the gardens".

On the way pulse is not found in any single entity, which realized what was happening. Moreover, the amygdala mobilizes the brain is completely scored and all channels of information to the cortex signal "every man for himself".





And that's after the man scared and ran away from the spider for a couple of quarters, the amygdala calmed down and finally impulse reaching the cortex. Citizen stops, takes the spirit and asks himself a rhetorical question: "What am I afraid of something?" Ie is again anticipating questions about why you can't beat a phobia with your mind or spirit.

And children with a phobia makes no sense to force to "be a man".

Sometimes phobias are irrational. Well, do not even think of such things you can be afraid. One lady was afraid of chicken feet, someone is afraid of butterflies, and all sorts of strange things occur. Often, these phobias are tied to early childhood. The mechanism is supposed scientists like this.

When a person is frightened, his attention focused narrowly on the possibility of the threatened object. It is also clear, need for a person to be closely watched risk and could quickly react. However, the child often can not accurately determine what is a threat, although the atmosphere can explicitly look threatening. For example, the parents quarrel or fight. He hears fierce voices, but not see them, but he sees a Teddy bear in the corner of his crib or yellow plastic duck. So she can commit to his memory.

That is the meaning of desensitizing therapies, when a person "accustom ourselves to fear."





These classes provide an opportunity for the bark to explore the object of fear, and to convince the amygdala that nothing dangerous there, or is there precautions that will help make the object of the fear is not terrible.

Medicines help approximately on the same principle. They inhibit the reaction of the amygdala and allow the crust to make assessment of what is happening. published
