Myths and ptifails about ” attention deficit “

28 Nov

It is common to associate the deficit of attention to the use of many devices , common nowCerebro because of digital technology , most researchers have stated that it is a myth , but let the cognitive point of view what happens .

Physiologically, the brain receives new information by the thalamus , it is a filter of attention, if you are talking to someone in a noisy environment, it blocks coming from outside to keep the information coming from the conversation.

If we train it is possible to change the ” task” , for example , leave the TV and read a text, but very things that draw the attention of the thalamus and the filter does not work , can cause a “dispersion” or so-called attention deficit , and these cases are many in the modern world .

Nerve impulses transmitted to the processing center , which is the cortex, a kind of shell the kernels of the brain , is capable of identifying different stimuli by the senses , for example, you eat the palate is active and is also talking , both information will pass through the thalamus and cortex to different region , which corresponds to the hearing ( conversation) and taste ( taste).

After recognizing the stimulus , the cortex sends information to the hippocampus , is that he is the commander of memory, ie , select what is stored and discards what he thinks essential, but this depends on the encouragement you give, eg , my father’s speech is not important, then discard , just want to enjoy and then forget , then discard .

Ended up seeing a basketball game with some friends , the game goes to a place to save because you felt happy and had an incentive to save , but saw the people that are in the game , and did not pay attention (not reinforced stimulus) , then it goes to the place where you can forget, or ever forget the next moment .

While the hippocampus works , you will giving a “featured” emotional all the information it deems important , helping to highlight what should be labeled, so it gives more value to certain information that you tell the brain that is important.

So forgetfulness is bound to like , to be desired and also to train the brain to what is important , most of the information we make ” an obligation ” is discarded .

This information is sent to the region called the amygdala (not to be confused with the throat), which gives an “emotional warmth ” to information , highlighting what is most striking to us .

So what ” we want to keep it” can not be a moment of “attention deficit”, for example : environmental discomfort , tiredness or something nasty side
