POPSHearing Voices – Underpinnings of Auditory Hallucinations
What exactly is going on in the brain during auditory hallucinations? And is the act of hearing voices inside one’s head always incontrovertible evidence of psychosis? In recent years, the use of MRIs, PET scans and other imaging technologies has given researchers some specific clues about these and other questions. This is very interesting, so far there was nothing that confirmed that there are any kinds of brain tissue abnomalities in schizophrenic people, this research, done by a group of researchers at the University of Bergen, Norway can help in the development of new therapy techniques on people with auditory hallucinations. They spotted an abnormal activity on a brain's area which is related to external speech (the right middle temporal gyrus), which can be the cause of language processing dysfunctions. Most notably, the group of British researchers hypothesized that if such language dysfunction “has its origins in early brain development, it might be possible to dete

POPSBrain Cells That Are A Key To Learning Discovered n experiments the researchers directly observed the convergent neurons where learning is suspected of taking place. These neurons responded to both a conditioned stimulus, in this case a novel saccharine solution, and an unconditioned stimulus, in the form of lithium chloride that made rats sick. Convergent activation is considered a key event for subsequent plasticity, according to Bernstein. Until now, however, there has been scant direct evidence of this activation during learning in the mammalian brain.

POPSPerception is contextual "The findings extend previous research into social emotion processing by showing that specific expressions in faces are processed differently in the human brain depending on the personality of the individual and the social context where the faces are perceived." i think these findings are "enlightening" :) a given human perception, interprets the signals according to the biases this perception is built from.

POPSBoredom a sickness or a creative tool? "In experiments in the 1970s, psychiatrists showed that participants completing word-association tasks quickly tired of the job once obvious answers were given; granted more time, they began trying much more creative solutions" "In a recent paper in The Cambridge Journal of Education, Teresa Belton and Esther Priyadharshini of East Anglia University in England reviewed decades of research and theory on boredom, and concluded that it’s time that boredom “be recognized as a legitimate human emotion that can be central to learning and creativity.”

POPSReason to Panic? The supply of oil is also related to the amount it sells for. It's not getting easier to find new reserves, but at $130 a barrel, a lot of companies are going to be looking really, really hard. They will also be reevaluating fields that couldn't be profitably tapped at $60 a barrel. The federal Energy Information Administration projects that U.S. production will rise 24 percent in the next decade. I actually have to somewhat disagree with that second statement that it's not getting easier to find new reserves. I'd offer that it actually is getting easier...satellite imaging, resonance mapping, new theories for oil location, and a whole host of technologies being applied, not to mention the cumulative experience of generations of drillers, all increase the likelihood of finding new reserves. Of course getting through bureaucracies isn't getting easier. So essentially it's a valid statement anyways

POPSCulture Influences Brain Function, Study Shows To read the full interesting article: http://www.sciencedaily.com/releases/2008/01/080111102934.htm There is so much to learn. What is interesting is how this affects testing as in schools or IQ. I think it may start to show what many of us already know. People think and perceive differently and need to be tested that way or tests not given the same importance. People/children learn differently. I have a strong opinion that things won't change very fast in the classroom though. But maybe parents can learn and appreciate what they have. Maybe people can start to appreciate differences and what we all bring to the table.

POPSPinpointing Genetic Changes The researchers isolated messenger RNAs from each sample and converted each messenger RNA into complementary DNA sequences. They then split each double-stranded DNA molecule into a smaller fragment and attached molecular primers to either end of the fragment, creating a tag. Seidman mixed the genetic tags with magnetic nano beads. Through a polymerase chain reaction, the team cloned millions of the same DNA sequence tags on each bead. The result was an amplification of an otherwise weak genetic signal.

POPSDetecting Photo Fakery Given that we are in the age of the Internet and along with it abject gullibility, here is an interesting page on how to detect photo fakery. Watch out for the REAL propagandists.
