A new study He examined the effects of the use of marijuana of 1,003 adults from 22 to 36 years of the human Connectome project compiled between August 2012 and 2015 and discovered that 63% of cannabis users for heavy -life exhibited a reduced brain activity during a task of a task of Working memory, while 68% of recent users also demonstrated a similar impact.
This decrease in brain activity was associated with a worse performance in working memory such as mathematical problems, where we retain and use information to perform tasks visualizing and manipulating the information mentally. Heavy users were considered young adults who had used marijuana more than 1000 times during their lives, while 10 to 999 times was labeled as a moderate user and less than 10 times a non -user was considered.
The tasks tested working memory, reward, emotion, language, motor skills, such as touching a finger to map control of the brain, relational evaluation and the theory of the mind and authors suggest a statistically significant effect on The function of the brain during the tasks of the working memory, it is unlikely that it is due to the random opportunity.
Because this is a transverse study that uses a functional magnetic resonance, this document is EXPLORATORY and should not be used for causal claims.
Since the effect was observed both in recent cannabis users and for life, but less significant for the other tasks, this shows the inconvenience of the use of the statistical importance of something significant as the colors of brain scanning to create conclusions, and why magazine editors should be critically seen in exploratory documents that invoke statistical significance.
During working memory tasks, researchers discovered that the use of heavy cannabis seemed to reduce brain activity in brain areas, such as dorsolateral prefrontal cortex, dorsomedial prefrontal cortex and the previous insula. These regions of the brain are linked to decision making, memory, attention and emotional processing.
As governments continue to allow the recreational use of marijuana, the effects of health will continue to be studied.
