A study recently write in the journalNeuroImagesuggests regular marijuana economic consumption can exit you with a " noisy " brain .
A squad of researchers at the University of Texas at Dallas used electroencephalography to monitor the brain activity of 38 volunteers ( 17 even marijuana drug user and 21 non - users ) when they were in a resting Department of State . This is plainly the first experiment to measure brainwave in marijuana user when they are not engaged in a task .
The resultant show that yes , unconstipated marijuana use leaves marks on the brain , even when you ’re sober . Specifically , they found it can increase cortical activity and connectivity , supportingother studiesthat have shown inveterate toilet smoke increase connection between dissimilar brain regions . This sound like a effective affair . ( After all , creativity has beenlinked to stronger connections . ) But the research worker say all this extra activity consequence in a " noisy " learning ability that has lost some of its nervous efficiency . Oh .
While marijuana use was consociate with dandy theta , genus Beta , and gamma moving ridge body process , it was also tie in to diminish delta undulation activeness . Delta wavesare the high - bounty , low - frequency wave associated with deep , dreamless eternal sleep , whereas theta , genus Beta , and gamma waves are all lower in bountifulness and higher in frequency than delta waves , and , therefore , link up with a more rattling mastermind state .
These change in neuronic action may relate to some of thecognitive impairmentsassociated with marijuana use , Shikha Prashad , pass generator and a postdoctoral scholarly person at the University of Texas at Dallas toldPsyPost .
To keep things fair and assure oddment of the drug were n’t tainting the results , the substance abuser were asked to refrain from light up in the 24 time of day prior to the study . Though , intelligibly , not everybody become the memo .
“ We did collect selective information on time since last function , which drift from 12 to 60 hours , and found no associations with neuronal activity , indicating that the burden were likely related to the on-going cannabis enjoyment , but this should be verified , ” Prashad severalize PsyPost .
It does , however , mean that these results show only the very short - term effects of marijuana use , which may not remain ordered over a longer - term follow - up survey .
It is also unreadable at this degree whether the changes in Einstein activeness are a verbatim effect of the drug itself or a consequence of substance use more generally . As with a slew of research that delves into marijuana use , the study is correlational rather than causational .
