Marijuana ’s mainpsychoactive compound , THC , may improve memory , according to a unexampled subject in shiner .
However , more enquiry is call for to see whether these findings would apply to people , the researcher said .
The researchers find that sometime mice in the bailiwick experienced " a dramatic improvement in cognitive social occasion " after the fauna were hand small dailydoses of THCfor about a month , said study co - author Andreas Zimmer , a prof of molecular psychological medicine at the University of Bonn in Germany .

former research in people — in stripling and immature grownup — as well as in young fauna has suggested thatTHC may in reality impair knowledge , but it was not clear how the chemical compound might affect the age brain in one-time individuals .
In the fresh study , the researchers look at 17 young black eye , which were 2 months old ; 24 mature mice , which were 1 class erstwhile ; and 29 mice that were 18 months one-time , take old for mice . The researchers implanted small pump into the bodies of all mice in the study . In about one-half of the mice in each age radical , the pump contained a smallamount of THCthat was unloose into the mouse ’s torso daily for about a calendar month . In the other half of the mice , the pumps hold a control substance , without THC .
The researcher then conducted a few behavioural experiment to quiz the mice ’s cognitive skills , include theirmemoryand ability to learn new information . For example , in one of the job , the scientists place the mouse in a pool of H2O with a hidden political program that allowed the rodents to escape the water once they could find it . In the control group , the mature mice and the old mouse took longer to memorise to climb out than the young mice .
However , both fledged mice and old mice that had been handle with THC learned the task quicker than the control mice in corresponding old age groups .
In some of the experiments , THC seemed to improve the memory in the Old mice to such an extent that some aspects of their memory were as unspoilt as those of unseasoned mice . [ 7 Ways Marijuana May Affect the Brain ]
However , in the younger mice devote THC , the chemical compound seemed to worsen their performance atcognitive task . This determination is in line with previous research that has show the detrimental core that THC may have on knowledge in young hoi polloi and animals , harmonise to the study , published today ( May 8) in the journal Nature Medicine .
To seek to see out the possible mechanisms behind the finding , the research worker also analyze how the THC interacted with gene expression in a brainpower area calledthe hippocampusin the mice . It turned out that administering the compound to the older mouse led to a change in those pattern , bring them back to a state standardised to the patterns seen in the young control mice . In contrast , administer THC to the unseasoned mice led to a factor face form that resembled that of the older control mice .
The researchers do n’t yet recognise if THC could help toimprove computer memory in aging human race , but they are planning tests , Zimmer said .
