Bartal expects to see this in rescue rats, because Empathy is manifested in these areas. But he was surprised that even the same he did not rescuing their comrades in a cage showed neural forms. He said: “The rats actually have a rat in trouble – that he has been trapped, and he is not happy. “And it makes people feel sorry for others, whether they help or not.”
If the same machine is burned all the time, but behavior between the group — and the two groups differ, what does it provide? The difference appears to be other sleep patterns, including nucleus accumbens, which activate carotransmitters of carrots and sticks such as dopamine, serotonin, and GABA. “It works when you eat something, or you win money, or you have sex,” said Bartal.
It is often referred to as a brainstorming facility, adding, “but nowadays, understanding that it’s not just a picture.” This new form of nucleus accumbens’ dopamine binds them together in anticipation of rewards and encourages adherence. “The main function of the brain is to get you close to things that will help you survive, as well as avoid things that are not good for you to survive,” Bartal says.
He repeated his experiments on the area using a technique called fiber photometry, which allows his team to monitor the movement of live rat nerves. He injected the animal’s injections with a gene that triggers neurons fluoresce each time the synapse breaks out. He then stretched out the power cords to watch the explosion, watching the rats roam around. And in fact, rats that release their mates showed the most dramatic events in the nucleus accumbens. Signs of the work went up as soon as they approached to open their door. This told Bartal that, because of rats roaming freely, the most important moment was to issue a ban, rather than just play with a friend.
Finally, Bartal connected rats with colored dice that originated in electrical outlets. He wanted to find out where the impact of the support began. (If hungry rats look for pizza By operating a subway system in New York, their sweetness is able to retain their findings.) By extracting brain fragments from animals as soon as they have completed the rescue and seeing areas where the dye has filled the pockets of c-Fos, they are able to identify other parts of the brain that communicate.
Bartal followed the call at a social center during the mouse rescue and found someone to identify him: the anterior cingate cortex. He doubts that this shows the connection between empathy and the rewards that can be important in understanding compassion. But it is still too early to “fully explain all the microcircuitry involved,” he says. “That’s what we’re working on now.”
“This is a very good lesson,” writes Robert Sapolsky of neuroscience in an email at WIRED. Sapolsky, who did not participate in the study, authored the book Be: Human Biology at Our Best, which describes the motivations for human actions – the ubiquitous “we” groups as opposed to “them.”
The team’s results tell us tons of information about ourselves, according to Sapolsky, because experts predict the same effects on the human brain: the difference between us / them, the initial lead in making demands, and what arouses interest. Testing for such a detailed brain test may not be impossible in humans, and it shows that this play with rats conveys a frustrating, audible message. The good news, Sapolsky writes, is that “the roots of our ability to help, to grieve, are not the result of Sunday morning sermons. He is older than we are, older than we are; his legacy has never been like that of animals.” our habit to them — if those around us are also old-fashioned.
