The research team claims to have found a new brain area associated with small body movements. It has come to light that we people may have some sort of extra thinking that can not be found in other primates.
The responsible person is neuroscientist George Paxinos and his team Neuroscience Research Australia (Neura), who designate their findings as endo-terminal core because it is located within the lower fetal foothold (endo). It is located on the bottom of the brain, close to where it connects the spinal cord.
This area is involved in receiving organoleptic and motor information from our bodies to refine our position, balance and movements.
"The lower cerebellar peduncle is like a river that carries information about the spine and brain stem cell," Paxinos said in ScienceAlert. "The endo-terminal nucleus is a neuronal group, and it's like an island in the river," he added.
Paxinos confirmed the existence of this brain structure by using the relatively new brain coloring technique he developed to make the images of brain tissue more clearer than the last neuroanatomical Atlas he has been working on.
The researcher had found out that the endorestform nucleus existed for decades. In a method called therapeutic therapeutic cordotomy, surgery to alleviate extreme and incurable pain by cutting the spinal cord, he and his colleagues found that the long fibers of the spine seemed to end up around the core of the endo-endiform.
In the location of this vague part of this hint, Paxinos suspects that it may be accompanied by a fine engine control, which also supports the fact that this structure has not yet been identified in other animals such as marmoset or rhesus monkeys.
"I can not imagine the chimpanzee playing guitar as cleverly as we did, even though they wanted to make music," Paxinos said.
Human beings are at least twice as big as chimpanzees (1300 grams versus 600 grams), and a greater proportion of brain neuronal pathways that show mobility are directly related to motor neurons: 20 percent compared to 5 percent cents for other primates.
Therefore, the endorestform nucleus can be another unique feature of our nervous system, although it is too early to say yet. That is why Paxinos is ready to do some work with chimpanzees soon.
In order to find out which function the endo-terminal core could serve, we may have to wait for a higher resolution magnetic resonance capable of examining it in a living human being.
It is a very popular myth that has expanded for years in society, which says that we use only 10 percent of our brains, many disappointment, it is completely wrong. There are even some who hold Albert Einstein as the founder of this myth.
There are two phenomena that can explain misunderstandings. Nine of the ten cells in the brain are so called. Glial cells that support cells and provide physical and nutritional help to other 10% of "thinking" about the cells responsible for neurons. But that does not mean that 90 percent do nothing, but only has other tasks.
Even so, even researchers can not fully explain certain abilities in the brain, such as dreaming, where memories are stored and how to access them, awareness or personality.
