    Why Marijuana Impairs Memory

    Scientists may have just found out why marijuana impairs memory and why the brain's natural versions of the drug might help against epilepsy.

    The active ingredient of marijuana, THC, is known to impair memory and to bind to areas of the brain linked to memory, such as the hippocampus. Still, the exact mechanisms by which marijuana impairs memory remain unclear.

    Neuroscientists David Robbe and Gyorgy Buzsaki at Rutgers University and their colleagues recorded hippocampus activity in rats. Normally brain cells in this region often synchronize their electrical activity.

    When the researchers injected rats with THC or a related synthetic drug, they found the normally synchronized workings of the hippocampus became disrupted. While the cells did not change how often they fired nerve impulses, their timing became erratic.

    Imagine an orchestra where the musicians are deafened and perhaps blindfolded, Buzsaki said.

    "They could still play their own pieces, but without any feedback from the other instruments played by other musicians or the conductor, depending on the nature and the length of the music played, it could be just a bit worse or outright disastrous, even though every note has been played. What is missing is the temporal coordination," Buzsaki explained. This is similar to what the researchers think goes on "in the hippocampal circuits under the influence of marijuana."

      I'd like a form of marijuana developed that would allow for selective amnesia

          Senior moments happen to me and I'm only 26
          Mostly when trying to remember dance moves!

                Take majiuana and there may not be much cheese in your fridge.

                  Hell, there may not be much of ANYTHING in your fridge... that includes those pickled onions that have been sitting at the back for years, and that Costco sized jug of mustard.
