Hypothesis: An increase in the number of D2 receptors in the brains
of rats trained to prefer alcohol will make alcohol less appealing and cause them to drink less of it.
Figure 1A shows the effects of exposure to [E.sub.2] (5 nM), E[E.sub.2] (0.5 nM), and BPA (50 nM) on luciferase expression in the brains
of ERE-TK-LUC-injected tadpoles.
STEVEN PINKER HAS BEEN called "science's agent provocateur" by the Guardian, named an "evolutionary pop star" by The Washington Post, as a "wunderkind" by The Washington Post, and acclaimed by the London Times as both a "world-class cognitive psychologist" and a stud-muffin of science." Yet Pinker, a professor of psychology in the Department of Brain
and Cognitive Sciences at the Massachusetts Institute of Technology, is more than a scientific superstar.
Rather than coding for a protein, as about half of known genes do, the newly discovered gene regulates the assembly of an RNA molecule that ultimately affects cell migration to critical brain
areas before birth, reports a team led by molecular biologist David Haussler of the University of California, Santa Cruz.
In fact, there is a saying that is as follows: As the bottom gets number, the brain
Using a brain-scanning machine called an fMRI scanner, the scientists were able to see that this level of pain sparked a lot of activity in a part of the brain
called the rostral anterior cingulate cortex.
Researchers Art Riegel and Edward French knew that when toluene was given to rats, it caused increased motor activity, known as "roaming." The researchers wanted to see whether this behavioral change in the rats' motor activity resulted from heightened dopamine activity in their brains
' pleasure center.
* Explain to students that they are going to read about an experiment in which researchers used positron emission tomography (PET), a noninvasive imaging technique, to compare dopamine transporter (DAT) levels in the brains
of methamphetamine abusers with those in non-drug users.
Criminal violence, for example, might be excused as a consequence of low levels of serotonin or monoamine oxidase in the brain
. Many philosophers, including Dennett, argue that humans should be regarded as responsible agents even if human behavior is fully determined.
shrink and our neurons short-circuit as we get older.
research is starting to confirm what many educators have known intuitively for years: Children learn better and remember more when their studies are mixed with music and drama, experience, emotion and real-world context.
SPECT also scanned a group of Franciscan sisters at prayer and found they, too, experienced a calming of this "orientation area" of the brain
, which gave them a "tangible sense of proximity to and merging with God."
bank currently has about 130 MS brains
in storage at the VA Wadsworth Hospital where it is based.
Schumann and Amaral used a computer-aided microscopic device to count neurons from representative sections of the amygdala in the preserved brains
of 9 males who had been diagnosed with autism and of 10 males who had no psychiatric or developmental disorders.
