Here is what I am reading today:
“In a study of more than 90 men, scientists from the University of Bonn, Germany, found that subjects treated with a dose of testosterone before the study told fewer lies than those who received a placebo. “Testosterone has always been said to promote aggressive and risky behavior and posturing,” says researcher and neuroscientist Bernard Weber. However, more recent studies indicate that it also fosters social behavior.”
“Why does making direct eye contact with someone give you that feeling of a special connection? Perhaps because it excites newly discovered “eye cells” in the amygdala, the part of the brain that processes emotions and social interactions.”
“On average, the residents of Sun City, Arizona, occupy their domiciles for a dozen years. When they depart—almost always by dying—they often leave their brains behind. The stages of physical and mental decline take them from their dream house to a hospital off Del Webb Boulevard, then to a nursing home, and finally back to the medical complex, where researchers harvest their most important organ. “
” Bob Moreno took these images of the possible meteor just outside of Santa Rosa.”
“A potential new treatment for traumatic brain injury (TBI), which affects thousands of soldiers, auto accident victims, athletes and others each year, has shown promise in laboratory research, scientists are reporting. TBI can occur in individuals who experience a violent blow to the head that makes the brain collide with the inside of the skull, a gunshot injury or exposure to a nearby explosion. The report on TBI, which currently cannot be treated and may result in permanent brain damage or death, appears in the journal ACS Nano.”
“The international team of scientists, led by Professor Inder Verma and geneticist Dr Dinorah Friedmann Morvinski, both of the Salk Institute for Biological Studies at La Jolla in California, studied the development of malignant glioblastoma tumors in mice. They had earlier developed a new method of researching cancer by using viruses to introduce cancer-causing genes (oncogenes) into the mice brains, as reported in Phys.Org.”
“The University of Exeter study says such injuries can lead maturing brains to “misfire”, affecting judgement and the ability to control impulses.
It calls for greater monitoring and treatment to prevent later problems.”
“Findings showed that when resting, the right hemisphere of the brain communicates more with itself and the left side of the brain, than when the left hemisphere talks to itself and communicates to the right side of the brain, regardless of participants’ dominant hand. Neuroscientists did note that right-handed people used their left hemisphere at a higher rate, and vice versa.
The authors of this study say that during rest, the right hemisphere is “doing important things, we don’t yet understand.” The activities that are being processed by the right hemisphere could be storing and processing acquired information, daydreaming, or similar creative tasks. Andrei Medvedev, Ph.D., an assistant professor in the Center for Functional and Molecular Imaging at Georgetown explains….”
“Scientists have learned how to discover what you are dreaming about while you sleep.
A team of researchers led by Yukiyasu Kamitani of the ATR Computational Neuroscience Laboratories in Kyoto, Japan, used functional neuroimaging to scan the brains of three people as they slept, simultaneously recording their brain waves using electroencephalography (EEG).”
“Oliver Sacks, HBO and others have chronicled the life of autistic savant Temple Grandin. The unique patterns of thought produced by Grandin’s brain enabled her to design now-ubiquitous methods to treat cattle more humanely, and she has served as inspiration to others diagnosed with the condition. Until now, no one has tried to assess the actual brain physiology of the professor of animal sciences at Colorado State University.”
“Brain scans of 638 people past the age of retirement showed those who were most physically active had less brain shrinkage over a three-year period. Exercise did not have to be strenuous – going for a walk several times a week sufficed, the journal Neurology says.
But giving the mind a workout by doing a tricky crossword had little impact.”
“Eating a raw food diet is a recipe for disaster if you’re trying to boost your species’ brainpower. That’s because humans would have to spend more than 9 hours a day eating to get enough energy from unprocessed raw food alone to support our large brains, according to a new study that calculates the energetic costs of growing a bigger brain or body in primates. But our ancestors managed to get enough energy to grow brains that have three times as many neurons as those in apes such as gorillas, chimpanzees, and orangutans. How did they do it? They got cooking, according to a study published online today in the Proceedings of the National Academy of Sciences. “
