Adult brains grow new neurons, and scientists have finally pinpointed where they come from

    For at least six decades, neuroscientists have been arguing over a big, foundational question: Do adult brains make new neurons? This process of “neurogenesis” had been shown in other adult animals, but its evidence in humans was circumstantial—until now.

    Bullshit…

    We’ve known since the 90s because of cancer drugs.

    Autopsies of people who received certain kinds of treatment showed neurogenesis because some braincells included certain isotopes that couldn’t have been present in the body before treatment.

    This is the first I’ve ever heard there was a “controversy” about it.

    Fo fucks sake, we’ve known multiple ways to make it happen for years.

      I remember in DARE (drug abuse resistance education) in middle school cops would preach on the (false) point that “you only have so many brain cells,” and that any and all drug use caused “permanent, irreversible,” brain damage.

      God I hate cops.
