It is going to be a part of the city in the so-called sensory-motor cortex, a brain that in humans and animals in action as we touched.
As in rats, the cells in the ‘kietelgebied’ are stimulated with electrodes, the animals loud giggle, and on the ground. That report German researchers in the scientific journal Science.
The scientists kietelden rats first in several ways: under their feet, on their backs and on their stomachs. The animals appeared from all of these touches to enjoy. As the tickling stopped, ran the rats behind the hand of the researcher, as if they asked for more.
Eventually, the scientists also electrodes on the sensorimotor cortex of the animals to the brain cells, to map who responded to gekietel.
“Our data suggest that we kietelgebied in the rattenbrein have been identified”, explains principal investigator Michael Brecht on news site Phys.org.
Utility
The fact that the rats are so delighted to respond to gekietel, points according to Brecht that tickle a particular purpose. “Perhaps it is sensitivity to tickling some sort of a trick of the mind that interaction and game rewards”, says the researcher.
