The Journal of general physiology 58 6, I was looking for the effects of 1 channel, 2 channel, 3 channel, 4 channels kind of thing. I won my age group once upon a time in the Philadelphia marathon, so that was nice.

Bertil Hille – Wikipedia

I managed to measure that on an axon down in Chile and had an abstract in the Biophysical Society in that, in fact, got the story more or less right chuckles. Shopbop Designer Fashion Hlile. Do you have another?

And they actually in the end put in sinusoidally modulated light into the Limulus eye and measured the voltage in the Limulus photoreceptor, which became sinusoidal. As the field evolves, some of the basic assumptions are hiloe to have to be re-examined.

If I remember the Dodge and Frankenhaeuser paper, they essentially confirmed for the node the Hodgkin and Huxley analysis of the squid axon, with the exception, I forget, there was no inactivation or there was less inactivation.

And so Tim this was his first year at Yale too didn’t talk to me much, but every once in a while would slip me a note and say, try reading this interesting paper. Low to High Price: They don’t say potassium channel, I don’t think. But that must have been just a wonderful result. And then when you got to the discussion, I would say, therefore, now we have separate places and we are going to call these sodium channels and potassium channels.


And that I did just by going to the library and reading. So it looked as though quite clearly there were two separate TEA sites, one at the inner end and one at the outer end, and they had different properties. Clay certainly used potassium channel right away, without question. There were people like Lars Onsager, who invented irreversible thermodynamics. Now this was the beginning of the graduate program at Rockefeller, if I remember correctly? Learn more at Author Central.

It was not clear how ions pass through channels, how channels achieve their remarkable selectivity for ions, nor how the voltage across the membrane instructs the channel to allow ion flow or to block it. An alternative would be that the pore fluctuates through frequent rearrangements of many constituent parts.

I liked biochemistry, even anatomy I hilld a lot. In a beautiful sequel to the bertio work, Rod showed that the bacterial channel can be blocked by a scorpion toxin that blocks potassium channels in higher organisms. At the same time, I found that a certain ion would go twice as well, or half as well or whatever, as sodium ions by the criterion of measuring the reversal potential, which is the voltage at which the current goes to zero.

So I was maybe the sixth class. You can’t go higher than picosemens, I said, and that’s about the highest channel that we know of even today. They just used those five. Joseph Erlanger Washington University. His work provided the first bdrtil description of an ion selective channel. So I absolutely love the place. Or I would just thumb through the pages and look for pictures and say, “Oh, that’s an interesting compound. Bertiil papers would always start out by saying—my papers—that we could block the sodium current with this and then the potassium current with that.

Dan Tosteson was the chairman and Paul Horowitz was a huge attraction for me.

It’s a fascinating insight into your career, and into the channels, and what a pleasure. What is the physical nature of an ion channel? Vaishali Merchant University of Calgary. And that was a very European style of upbringing in a way. D, Hille did postdoc research with Sir Alan L.


So I regard it as extremely important and also medically important. I love the Sierras, where we’ve also walked with great fondness, but the angle of vision involved in taking in these mountains in Nepal and particularly in the Everest region is, well, one certainly has to crane one’s neck to see the tops of things. That was the standard structure that I had.

Bertil Hille, who shared Clay Armstrong’s belief in ion channels long before the proof was in, says they envisioned “holes in membranes” in the early s and were convinced that the “holes have gates that open and close. In fact, I was in the screened room right next bsrtil his office and using equipment that he had designed for measuring hikle waves.

Zipper Idea Armstrong comments on the origin and confirmation of this idea and bergil with encouragement for young scientists hillle enter the channel field.

And slowly, you know, increasing our general knowledge of the universe. And actually I have a letter right here in front of me. The pore loop amino acids form the selectivity filter in the teepee’s wide end, where potassium ions on their journey across the membrane interact with backbone atoms from the signature sequence amino bretil.

And I personally thought that the currents carried by sodium ebrtil and those carried by potassium ions must be going through different places. So I actually took rather nice courses in all of those subjects, which most zoologists wouldn’t do. And do you two talk science? We started on the gating current experiments, I think along in the early ’70s. Shopbop Designer Fashion Brands.
