Scientists may have just found out why marijuana impairs remembering and why the brain ’s rude interpretation of the drug might help against epilepsy .
The active factor of marijuana , THC , isknown to impair memoryand to bind to areas of the brain linked to memory , such as the hippocampus . Still , the exact mechanisms by which marijuana impairs memory remain indecipherable .
Up in Smoke: Marijuana Toasts Memory
Neuroscientists David Robbe and Gyorgy Buzsaki at Rutgers University and their colleagues recorded hippocampus activity in informer . Normally encephalon cells in this region often synchronize their electrical activeness .
When the investigator injected rats with THC or a related to synthetic drug , they found the normally synchronized working of the hippocampus became disrupt . While the cubicle did not change how often they raise cheek impulses , their timing became temperamental .
Imagine an orchestra where the instrumentalist are deaf and perhaps blindfolded , Buzsaki said .
" They could still represent their own pieces , but without any feedback from the other legal document act by other musicians or the director , depending on the nature and the length of the music played , it could be just a moment worse or instantly disastrous , even though every bill has been played . What is lose is the temporal coordination , " Buzsaki explained . This is similar to what the investigator intend goes on " in the hippocampal circuit under the influence of marijuana . "
The neuroscientists put rats through a standard trial run of store , where the fauna had to determine to alternate which centering they went in a tangle for get water . As rat hippocampal mind cell action arise less synchronise under the influence of drug , the gnawer made more mistakes . This suggest synchronized mind mobile phone action is all-important formemoryformation and hints that THC impairs computer memory by disrupting this synchronize activity .
The scientists suggest the mode THC disrupts synchronize brain cell activity might avail fight capture . During seizures , brain natural action becomes abnormally synchronized . Prior inquiry suggested the brain ’s natural versions of THC , known as endocannabinoids , helped preclude seizure .
Whether or not marijuana is good against epilepsy rest indecipherable . anecdotical reports going back century say it can facilitate control gaining control , but animal studies bring out it could also provoke convulsion .
The neuroscientists report their findings in the December issue of the journalNature Neuroscience .
