As a result, older animals that have had an increased level of cortisol, the right turned in 58% of cases. At the same time 80% of the rodents with low cortisol easy to get to the tidbits.
Analysis of the scholars underwent tissue prefrontal cortex of animals Which determines short-term memory. It was found that in rats with elevated levels of this hormone was noted at 20% less synapses than animals that belonged to the second group and almost equal to young rats, the results of tests on the level of memory.
Thus, the researchers were able to conclude that the long lasting effect on the body of the stress hormone blows to substantial reduction in the number of nerve cells on the prefrontal area of the brain.
