There are too many answers to this question, and in a sense, THAT’S what’s wrong. I used this ‘headline’ as a cheap trick to get you to read my little story. I have a specific partial answer to this question in mind, which I would like to present to you by way of a little…
Race car driving was the last thing Marilyn Kays expected to be doing at the age of 63. Her late husband called her ‘grandma’ because of her pokey driving. After completing BrainHQ, where she made great individual progress, Marilyn felt more confident than ever before. She noticed that she remembered things like her bank account…
Dan has been making a lot of comments and asking a lot of questions, and I thought I’d take a crack at one of the latter. He specifically asks how a blind individual creates representations of the things of the world. What kind of internal ‘representation’ can the brain make, when it can never see…
There are several highly-ordered neurological representations of the surfaces of your body within a cortical region called “S1”, which occupies a narrow band that roughly bisects the cerebral cortex mantle from a location just above and in front of your ear, and extends from ear to ear. When you stimulate a specific location on the…
Alcohol is our best-studied neurotoxin. You can pickle a brain in booze. At somewhat lower concentrations that are quite easily achieved in drinking humans, ethanol alters synaptic spines and their plasticity, greatly reduces the complexity of neuronal interconnections, ultimately kills off your neurons, and shrinks your brain. Cognitive and motor losses are the predictable behavioral…
James B. Watson, the genetics pioneer, is the first individual in the history of the universe to have his DNA completely sequenced. In a statement that testifies to his infectious enthusiasm for nerd science (for which, if you’ve had a conversation with him, you know that Watson is obviously genetically endowed), Jim was “thrilled to…
My wife Diane and I visited our friend Mary in the hospital on Friday. Mary had just had her “knee replaced” — which is a rather spectacular modern procedure, unimagined not too many years ago. Another modern, commonplace aspect of this kind of surgery was being “enjoyed” by Mary at her morphine-on-demand dispenser! Her machine…
A couple of weeks ago, Jerry Emmons shared his story with Posit Science. It seems that the 84-year-old was spending much of each day re-living old, painful World War II memories. He had been the only survivor in his crew and the horror was haunting him more and more. “Post-traumatic stress disorder,” said his doctor.…
Neil Pearson wrote an inspirational and informative comment from a soldier on the front lines of pain therapy about my last entry [which described another neurological confirmation of an empathetic response actually engaging the pain centers of the brain, when a subject witnessed realistic (fake) videos of inflicted pain]. If pain is an issue for…
