The neuroplasticity bait-and-switch

As long as we’re talking about brains this morning, here’s another topic that irritates me: the abuse of the term neuroplasticity.

devneuro

Way, way back in the late 1970s, my first textbook in neuroscience was this one: Marcus Jacobson’s Developmental Neurobiology. (That link is to a more recent edition; the picture is of the blue-and-black cover I remember very well, having read the whole thing). I came into the field by way of developmental biology, and that means we focused on all the changes that go on in the brain: everything from early tissue formation to senescence, with discussions of synaptogenesis, remodeling, metabolism, transport, and functional responses to activity or inactivity. This is all under the broad umbrella of neuroplasticity, a term that’s at least a century old, and that is well-established as both a phenomenon and a science. That the brain modifies itself in response to experience is so thoroughly taken for granted that you can basically define neuroscience as the study of the responsiveness of neural tissue.

Memories: trust provisionally, but verify always

Steven Novella makes an important point: memories are fluid. There’s no VCR in your head, and no tape recorder either, and memories are constructs. You remember the framework (sometimes very poorly) of a past event, and your brain builds a plausible set of details around it. When you picture Christmas at your grandmother’s house when you were 12, you don’t have a record in your head of how many logs were in the fireplace or a second by second recording of the flickering of the fire. You remember that Grandma had a fireplace, and sometimes she had logs burning in it, and maybe there was a fire that year, and your brain obligingly assembles an image for you.

Bill Maher, nevermore

I never watched Oprah, because she was a gullible woo-artist; I don’t watch Dr Oz, because he’s quack; and now all I can say is fuck Bill Maher, because he’s a crank on so many things. On his latest show, he surrounded himself with Marianne Williamson, a “spiritual teacher” and proponent of prayer, Amy Holmes, a news announcer for The Blaze (Glenn Beck’s spinoff), and some guy who didn’t say much, and he went off on a grand tour of kook talk, confident that his panelists wouldn’t disagree with him. Watch. Be embarrased for him.

But I can understand them all!

This woman does 17 British accents (well, she cheats a bit and jumps over the Irish Sea a couple times). I’m an American, and a Yankee at that, so I’m a poor judge, but a few of them sounded a bit off. Also, I know she isn’t hitting all the variations: there were people all over the UK who’d say something to me in a particularly thick local speech variant, and it just sounded like Dutch being gargled through a misfiring diesel engine, to me, and that was just Alan Moore.

I hear the Danes don’t much like Lomborg, either

Once again, I am reminded that I’m in the wrong business to make money. Bjorn Lomborg is in the news again, and I learn that the man makes $775,000/year for running the Copenhagen Consensus Center…which is a drop box in Lowell, Massachusetts. I don’t think buying a mailbox is the secret, though — I think you also have to convince the Koch Brothers to deposit checks in it. Apparently the trick behind that is to lie persuasively about science in a way that allows very rich people to become more rich.

Those wacky Italians

Pope “Not in the face! Not in the face!” Francis has been offering advice on child-rearing, based on his deep experience with the process, I’m sure.

One time, I heard a father in a meeting with married couples say ‘I sometimes have to smack my children a bit, but never in the face so as to not humiliate them’, Francis said.

How beautiful. he added. He knows the sense of dignity! He has to punish them but does it justly and moves on.
