A group of scientists say they have discovered a new region of the brain associated with minute body movements. It turns out that we humans can have some extra thought that is not found in other primates.
Neurologist George Paxinos and his team at Neuroscience Research Australia (Neura), who named their discovery as an end-end nucleus, is inside the endo of the smaller cerebral stem (also called the "restiform body"). It is located at the base of the brain, near where it is connected to the spinal cord.
This area is involved in obtaining sensor and motor information from our bodies to improve posture, balance and movement.
"The weaker brain is like a river that carries information from the spinal cord and the brainstem of the cerebellum," says Paxinos in ScienceAlert. "The endothermic nucleus is a group of neurons and is like an island in that river," he added.
Paxinos confirms the existence of this brain structure by using a relatively new brain staining technique that it develops to make the brain tissue images clearer for the last atony of the neuronatomy on which it worked.
The researcher received clues that the endothelized nucleus existed for decades. In a procedure called anterolateral therapeutic cardomatomy, surgery to relieve extreme and incurable pain by cutting the spinal cord, he and his colleagues noticed that the long fibers of the spine seem to end around the endogenous nucleus.
The location of this elusive part of the brain makes Paxinos suspected of being involved in fine motor management, something that is also supported by the fact that this structure has not yet been identified in other animals, including marmosets or rhesus monkeys.
"I can not imagine how chimpanzees play on the guitar as smart as we do, even if they like to make music," Paxinos said.
People have brains at least twice as large as chimpanzees (1300 grams vs. 600 grams), and a higher percentage of brain neuronal pathways that show motion make a direct contact with motor neurons: 20 percent compared to 5 percent in others primates.
Therefore, the endothelial nucleus may be another unique feature in our nervous system, although it is too early to say yet. That's why Paxinos is ready to work with chimpanzees soon.
To understand what function the endo-terminal nucleus can serve, we may have to wait for higher resonance magnetic resonance capable of studying it in a living person.
There is a very popular myth that has been growing in society years that say we use only 10 percent of our brain, the disappointment of many, it is totally false. There are even some who attribute to Albert Einstein as the founder of this myth.
There are two phenomena that can explain misunderstanding. Nine of the ten cells in the brain are called glial cells that support cells and provide physical and nutritional support to the remaining 10% of cells, the neurons responsible for "thinking." But that does not mean that 90% does nothing, there are only other features.
Nevertheless, even scientists can not fully explain some of the powers the brain possesses, such as dreaming, where memories are stored and how to reach them, consciousness or personality.
