Scientists identify the brain structure that filters awareness
Our conscious conscious consciousness can govern a deep structure in the brain

Neuroscientists have first seen how deep brains are activated when the brain knows its thoughts, known as conscious perception.
Is the brain Constantly bomb With views, sounds and other stimuli, but people never know the world’s sliver, such as the taste of a chocolate or someone’s voice sound. Researchers have long known that the outer layer of the brain called Cerebral Cortex, involved in this experience to know specific thoughts.
The involvement of deep brain structures has been much more difficult to clarify because they can only access invasive surgery. Designing experiments to test the concept of animals is also tricky. But the study of these regions would allow researchers to expand the theory of consciousness beyond the brain wrapper, the researchers said.

“The field Examinations of consciousness It brings a lot of criticism and skepticism, because it is a phenomenon that is so difficult to learn, “says neuroscientialist at the University of Israel’s University. But scientists have systematic and strict methods have had systematic and strict methods Research awarenessHe says.
Knowingly or not
In a published study Science Today, Mingsha Zhang, a neurospiestist, beijing is usually focused on the University of Thalamus. This region in the center of the brain is involved in processing sensible information and work memory and is considered the role of conscious perception.
Participants were already experiencing serious and sustainable therapy headacheTo do this, the thin electrodes injected their brains. This allowed Zhang and his colleagues to study brain signals and measure conscious consciousness.
Participants were asked to move the eyes in a certain way, according to a flash icon noticed in front of you on the screen. The icon was designed so that participants can only know half the time.
During tasks, researchers recorded neural activity in multiple brain regions, including Thalamus and Kortex. It is the first time that the simultaneous recording performed by the tasks important for science consciousness. Christopher Whyte, Sydney University Sydney Systems Australia. The work is “very noticeable,” he stated that the group allowed the time to see the time of neural activities in different regions.

When the participants’ activity were aware of the appearance of the prefrontal thalamus and kortex icon, they were not according to the activity. The activity they were aware of the icon appeared earlier and was stronger in the sections of Thalamus than in the cortex sections, and seemed to be coordinated in both areas. This suggests controls that Thalamus senses and controls thoughts, which, Mac Shine says that it is a neuroscientist of Sydney University.
Previous animal studies support these findings. In a 2020 role, the researchers used to move the individual mouse rumors that the mouse noticed half time. The animals were prepared to take a water drain when they felt the movement. Researchers found that when the cells of the brain cortex were activated, when the mice were directed to the deep regional regions of the brain.
The final examination is one of the most worked and widespread research on the role of Thalamus consciousness, “says MUD. However, tasks wonder whether the neuric activity associated with conscious experience.
Zhang predicts more people experiments and researching brain activity in detail in monkeys.
