Let's stop thinking that we only use 10% of our brain

hellojoy12

In the collective imagination there is a belief that humans only use 10% of the brain. When that barrier is overcome, surprising abilities appear and life improves. The statement is usually taken up by films like Lucy (2014) and Limitless (2011). Neurologists and psychologists are tired of repeating that this is false. The human uses all of his brain all the time, although not with the same intensity.

The myth of little use of the brain is extremely inaccurate, experts say. The statement does not specify what this supposed 10% use corresponds to. It is also not clear whether the limitation is in the volume, energy meta Phone Number List bolism or electrical activity of the organ. Using a tenth of any of the options means forgetting about bodily functions that operate automatically. Staying alive involves the use of all your areas.

Visual processing is carried out in the occipital lobe, the coordination of voluntary movement lies in the frontal lobe, and the recording of sounds is in the temporal lobe . The cerebellar region is activated when we perform complex tasks without paying attention to them. Day-to-day tasks are distributed in the kilo and a half of neuronal tissue.

The brain of lonely people is different
Brain activity is different between people who feel lonely and those who don't. But it is also different among the loners themselves.
Neurologists know which regions are activated in the organ thanks to functional magnetic resonance imaging. The technique measures changes in brain blood flow. As a general rule, the more a brain region is occupied, the more energy it requires and the greater amount of blood it receives. Harvard University evolutionary neuroscience professor Erin Hecht, in an interview for Lives Science, compares the mechanism to the heart. There is no such thing as using only 30% of the heart. The organ has periods of low activity, such as when we sleep, periods of high physical demand, and is prone to failure if we do not take care of it.



Brain regions do not function in isolation and it cannot be assumed that the body's functions inhabit an exclusive area, scientists warn. Neurons, minimal units of the organ, communicate with each other forming electrical networks throughout the tissue and adapt according to the needs of the individual.

We occupy the entire brain, but its efficiency can be improved
Following the metaphor of the heart, the brain can be trained so that certain actions are executed better with less investment of energy. The organ can also grow. When we practice a skill until we master it, the regions associated with it expand without researchers being clear about the explanation. The best hypothesis so far is that the branching of neurons with neighboring cells and the increased blood supply expand the mass of the organ.
