Do You Know? Things You Learn Depends Upon How Brain Works
Editorials News | Jan-11-2019
Neuroscientists know a lot about the brain learn new things, but how they choose to focus while leaning new thing. Now, the researcher has come up with the ability to an unexpected place.
According to the Stanford Biologists report OCT 26 in Science, they think they’ve figured out how animal sort through the details. A part of the brain called Para ventricular thalamus acts as the gatekeeper, making at that the brain activity and tracks the most silent details of the situation. Researchers funded in part of Wu Tsai Neuroscience Institution’s.
What you learn:
In its most basic form learning comes down to feedback. For Example, if you having a head ace and decided to take a drug, you expect that drug will make your Head ace go away. If it effect, you will take that drug again you have Head ace. If it’s useless from the next time you take something else. Psychologists and neuroscientists have studied the aspect of learning extensively and even traced to the specific part of the brain that process feedback and drive leaning.
The picture of learning is still incomplete. Chen said “Even in the relatively uncomplicated laboratory experiments, let alone life in the real world - human beings , animals need to figure out what to learn essentially, what’s feedback and what noise, despite that need, it’s an issue Psychologists and neuroscientists have not paid much attention to.
Researcher replaced the air puff with mild electric shock. The team found that neurons in the Para ventricular thalamus tracked that change. During the air puff phase, two third of PVT neurons responded while an additional 30 % activated only by the odor signal water. In other words, during this process the PVT responded both good and bad outcomes, but there is greater response to good outcomes.
A new place to look and to tweak:
Neuroscientists also have a new way to control learning, Chen and other researchers said that in additional experiments with mice modified so the team could control PVT activity with light for example they could more quickly teach mice than no odor, no longer reliably signaled water was coming, and another odor had switched from signal water to signaling a shock.
