Scientists were able to understand all the mechanisms of human memory.
Scientists at Massachusetts General hospital, under the leadership of Joshua Roffman, set it as the dopamine receptors ensure the functioning of working memory (the ability to keep in mind pieces of information to solve the current task). It turned out that dopamine receptors redirect cognitive resources to support the work of the brain.
The publication notes that dopamine is a neurotransmitter that communicates between neurons and is also responsible for feelings of pleasure and reward, and plays a role in the switching process from one cognitive activity to another.
The lack of dopamine leads to inertia and lethargy of human behavior, as it forms the signaling pathways that are necessary for the functioning of working memory.
However, in the prefrontal cortex there is also a default network that is not associated with the decision task. She needs to be silent to activated other neural circuitry.
Until recently, these switching mechanisms have remained unknown. However, a recent study in which experiments were conducted with 100 people helped to make that clear.
It is reported that the subjects had to solve simple mental tasks, and meanwhile, their brains were scanned using positron emission tomography.
In the end, it turned out that the density of dopamine receptors depends on how fragmented the default and frontoparietal network (involved in the functioning of working memory).
The result of this study will help scientists better understand the nature of schizophrenia and other neuropsychiatric ailments.
