TODAY'S TREATMENTS Most antidepressants work by tweaking levels of various neurotransmitters, the chemicals that carry signals from one neuron to another. Prozac, Paxil, Zoloft and the other SSRIs slow the absorption of serotonin. Effective antidepressants that act on both serotonin and norepinephrine include Effexor and Remeron. Drugs like Wellbutrin work in a similar way but probably on the neurotransmitters norepinephrine and dopamine. The tricyclic antidepressants (such as Elavil and Tofranil) also blocked the absorption of neurotransmitters, especially norepinephrine, but the drugs had significant side effects. Another class of first-generation drugs, the monoamine oxidase inhibitors (MAOIs) such as Nardil...
...Poem? Is it the fierce deliberation of one man’s mind that gives it its peculiar flavor, its unmatched intensity, and its startling command of the intellect of the great intellects who devour it? Or is it the beauty of its poetry that seems to penetrate each neuron of the brain...
...professor. She writes popular-science books, presents TV series like last year's Brain Story on the BBC and delivers public lectures. Last week she chaired a conference on music and the mind, which yielded intriguing insights into the way melodic patterns may be linked to the configuration of neuron networks in the brain. Her telegenic looks, designer clothes, accessibility and enthusiasm for her subject - the mind and how it works - have led the media to dub her Britain's only celebrity scientist. She doesn't mind the tag: it gives her a platform to speak out on issues about...
...evolutionary biology--think of it as Earth's R. and D. department--is influencing the way we build computers, write software and organize companies. One member of our panel, Ray Kurzweil, an inventor, technology futurist and entrepreneur, observes that the human brain has no single "chief executive officer neuron." What gives the brain its power is not one boss but the ability of billions of neurons to conduct trillions of operations instantaneously. In computer lingo, that's called parallel processing, and it is something that today's man-made computers can accomplish only crudely. In everything from biology to business...
These are the neuron-packed gray matter of the cerebral cortex and white matter, which contains the fibrous connections projecting to and from the cerebral cortex and other areas of the brain, including the cerebellum. Perhaps, Courchesne speculates, it is the signal overload caused by this proliferation of connections that injures the Purkinje cells and ultimately kills them. "So now," says Courchesne, "a very interesting question is, What's driving this abnormal brain growth? If we could understand that, then we might be able to slow or stop...
