In Membrane potential dynamics of GABAergic neurons in barrel cortex of behaving mice, Gentet et al use two-photon imaging to guide dual, whole-cell patch clamp of inhibitory and excitatory neurons in the mouse barrel cortex.  These mice are head fixed, but awake and naturally whisking.  The authors can then see how the membrane dynamics of both subthreshold and suprathreshold voltages are correlated across pairs of cells.  Differences between the correlations for excitatory and inhibitory neurons shed light on how cortical circuitry processes sensory information in natural brain states.

Were the oldsters previously infected with a related influenza virus, or is there another explanation? The sera of individuals born in the early part of the 20th century have antibodies that block infection with the 2009 H1N1 virus.  We also know that antibodies that prevent infection with recently circulating seasonal H1N1 viruses do not react with pandemic H1N1 strains. These findings may partly explain the lower incidence of influenza this year in individuals greater than 65 years of age (illustrated). But other factors might also be responsible for safeguarding the older population. Infection of guinea pigs with a 2007 seasonal H1N1 virus confers some prot... virology blog blogs http://www.medworm.com/rss/comments.php?id=3016928 Mon, 02 Nov 2009 22:30:57 +0100 3016928 http://www.medworm.com/index.php?rid=3016929&cid=t_240498_139_f&fid=38879&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2FVirologyBlog%2F%7E3%2FAxucwQXP7OQ%2F “Do Women Need Such Big Flu Shots?” suggests that we would have more doses of influenza 2009 H1N1 vaccine if we accounted for the biological differences between men and women. The idea is that women generate a stronger antibody response than men, and therefore require less vaccine. Does this idea have scientific support? The opinion is based in part on a study carried out in 2004-05, in which adults were immunized with full (15 micrograms) or half-doses of trivalent inactivated influenza vaccine. This vaccine, made by Aventis Pasteur, contains influenza H3N2, H1N1, and B strains. Serum samples obtained before immunization and 21 days later were assayed for antibody response to each strain of influenza by hemagglutination-inhibtion.

Brain Teaser 1. In which direction is the bus pictured below traveling? Do you know the answer? The only possible answers are "left" or "right." Still don't know? When pre-school children were shown this picture and question, they all answered "left." When asked why, they answered "Because you can't see the door." Believe it or not, this simple teaser generated a very lively controversy with over  50 comments...some of my favorites "I've been looking at the bus for a long time now and it is not moving at all" (Peter), "Fools! It is falling, because there is no ground under it! How's that for logic? (Richard), and "I would like to r...

Much of it shows that doctors do not understand the way that this new incretin drug works to lower blood sugar and are therefore prescribing it inappropriately. As a result, a lot of people who are taking Januvia report seeing very high blood sugars. Let's look at why this might be and what it tells them about their true medication needs. The main way that Januvia lowers blood sugar is by raising the level of a substance, GLP-1, which is produced in the gut and has the ability to do several things. 1. GLP-1 stimulates the beta cell to secrete insulin in a manner very similar to that of the sulfonylurea drugs like Amaryl and Glipizide (sulfs). What i...
