Alcune people are more 'susceptible to stress because of other' produce more 'neurons after a negative event .
I found a study of ' University' of Texas published in the journal PNAS .
Through a series of experiments on mice, researchers have found that having had a stressful week after the animals had shown that most 'likely exhibited increased neurogenesis, that' the birth of new cells in the brain.
Or rather, the surviving cells produced more 'produced by the new ones less susceptible mice.
Furthermore, blocking neurogenesis even more rats' stress react better to the difficult situations.
"This work shows that there is 'a period of time during which you may be able to alter the memory about a particular situation by manipulating the cells generated in the brain - said Amelia EISC, one of the authors - that we can' help in the meantime to understand why 'people react so' different stress each other. "
The researchers exposed mice to negative emotions by putting them in a cage with mice more 'aggressive for 5 minutes a day, after testing their susceptibility' to stress. Both types of guinea pig showed the same production of new cells at once after the negative event, but within a few weeks those who had shown more 'stressed they had many more'
