  1. hmmm, good question. Your first example, e.g. conditioning a rat to press a lever only after a specified time I can tell you it is done often. Our laboratory does these experiments and I'm a contributing author on the paper. We trained a group of rats so that they press a lever every 16 seconds for a food reward. If they press too soon, the time resets. Thus, after some time, we are able to say that the rat can reliably judge the passage of 17 seconds. Then we gave the rat LSD and watched the shift. LSD is known to alter human perception of time, and it did the same for the rat. Your second example is more complex. COuld we train the rat to press sooner and sooner each time? hmmm, I'm not sure. If we kept the intervals exactly the same each time, I think it's possible. To my knowledge however, it hasn't been done before.
  2. Sounds dumbn, but here at my University they have plastic bins for radioactive waste. Those might be nice since you coiuld see through the case and store radiation in it. It's interesting to me because the radioactive materials the university receives are tightly regulated. In this day and age I'm a tad surprised you can get these materials.
  3. I'm no mathematician, but in addition to models, I'm sure city planners, etc. sample traffic patterns. Obviously there will be a much heavier flow of traffic during rush hour VS. the middle of the day. All they have to do is count the number of cars passing a particular spot. Then they time or adjust the traffic lights accordingly. I see this on my way to work. The "timing" of the lights changes depending on the time of day.
  4. Seems that if it works and is relatively free of side effects then it's fine and progress marches on. Our laboratory did some studies on ginkgo biloba a few years back. What we found was that rats given ginkgo biloba were able to leanr how to complete a maze in less sessions than those given placebo. Seems to work, unless it has horrendous side effects, I'm all for it.
  5. Anyone else ever notice that at certain times of the year you'll find tons of dead ladybugs indoors, or in window panes?
  6. It's a personal preference (and I get it free from my school), but I use Norton Antivirus Corporate edition. Works wonderfully in my opinion.
  7. It also has to do with the individual and his/her personality. Most "bass heads" are kids under the age of 25, who drive around in cars saying: "Hey look at me, I have the world's most obnoxious stereo". I did it too, but I lost my need for attention right around age 20. And also, as many have stated, it probably more the type of music rather than the bass its self.
  8. I have a question thats a bit off-topic. I have an older coffee table with a glass top. Since it's somewhat older, the glass top has some scratching on it. How does this happen if a diamond is one of the only things that can cut glass?
  9. Well, what blike said in post #2 is still you're largest problem. How will you identify neurons involved in "positive" versus "negative" feelings? Also umm, are you writing this paper just for practice and your own interest? (whats the purpose).
  10. I'm running an Intel 2.6 Ghz on my Dell. There is a boot screen where I can simply turn hyperthreading on and off. I don't remember the exact command, but it's hitting something like F1 during startup. I'm fairly certain mine was enabled when I bought the comp. as well.
  11. Seems like the link is broken. I thought I saw "post-doc" on there the first time. I'm glad I'm breakin my balls through graduate school just so I can have a shot at one of the worst jobs in science. LOL
  12. Yeah, I agree. However why does a comp. seem to slow down after long term use? For instance, I bought my computer 6 months ago. I formatted as soon as I got it. Now, 6 months later it doesn't quite operate as fast. No MAJOR slowdowns, but small things. For instance, if I transform 20 mp3's into .wav files for burning. I can see it has slowed down somewhat. A slightly more extreme case, I had used my last PII 400 mhz. directly out of the box. Used it for about 4 years straight. It started to get old and quirky, and someone recommended I re-format. I took the advice and noticed a large improvement of performance, still running the same programs and same hardware. Just curious. Anyone else have similar stories?
  13. I have a question for the computer experts: "whats one of the first things you do when you buy/receive a new computer?" For me personally, I format the HD. I do this because I usually buy brand-name computers with bundled hardware/software (gateways, dell etc.). My reasoning is that these "bundled" computers come with a million "Extra" features installed which slow down the computer. I feel that a clean install does wonders for a new comp. My gf just bought a brand new laptop (gateway). I've implored her to format the HD right out of the box. I claim it'll increase the performance of the computer, and make it operate more smoothly and efficiently. She refuses to believe me. Am I correct in my assumption? Does anyone have any references to back up my cause? Comments/thoughts?
  14. You'd be surprised at how much you can learn. My professor always claims that in reality he's a disgruntled english teacher. I figured out exactly what he meant when I was writing my first manuscript for publication. Writing is something that takes a lot of time, effort and patience to do correctly.
  15. There was a thread on fevers a while back. Glider, I thought the info on white cell production was interesting. Anywho, doesn't fever also impede the growth of bacteria?
  16. I would think you need more of a chemistry degree to synthesize drugs. I'm getting my degree in pharmacology and I'm hoping to land a job with a big firm testing and characterizing the drugs the chemists produce. I'm not sure about the market being saturated, it'll depend on what you want to do. The guy I work with that recently graduated from my lab had plenty of options. You mentioned psychiatry and being a general practitioner, but keep in mind you'll have to go through medical school for those.
  17. Seems decent. I didn't think it was superior to medline however (at least for the subjects I usually search for). Still needs a way to search by author and/or year of publication etc. I wonder how this particular search engine works. Usually for online journals the author selects a few keywords which will result in a "hit". I wonder if it searches by number of links or whatever the same way normal google does.
  18. In addition to the most obvious problem which Blike stated above. Look into the "blood brain barrier", and decide how it will get into the brain.
  19. Just adding a tad to jdurg's bit on narcotics. Some drugs have already been classified illegal and they haven't even been made yet!. Like jdurgs example of MDMA, there are all sorts of derivatives of MDMA as well. Many of these are illegal, even the ones that haven't been synthesized yet!.

  21. Why are you taking klonopin for anxiety? It is usually prescribed for seizures. If you have problems with anxiety an anti-anxiolytic makes more sense. Klonopin is a benzodiazepene and a general CNS depressant. While I have only briefly looked at some side effects and such, I haven't seen anything directly related to analgesics. This drug is habit forming and I would assume tolerance would develop. This is a wild guess, but for setting a shoulder the Dr. may have given you another type of CNS depressant to calm you down while you had your shoulder "set". Thus, if you've been on klonopin that long you probably developed some cross-tolerance to whatever drug the Dr. used.
  22. Can a correlation be made? Discuss.....
  23. Nothing major on my part. I've injected a few rats with the wrong drug before. I've also blown/puntured the aorta out of rats during perfusions. Basic mistakes, nothing too serious though.
