Researchers from the California Institute of Technology (Caltech) found in a new study that an area of your brain is hard-wired to respond to animals, whether they are cute and fluffy or ugly and threatening. No matter what your response is to animals, it could be thanks to that specific area of the brain that is hard-wired to rapidly detect other creatures. Working with researchers from UCLA, Caltech researchers report that neurons throughout the amygdala -- a center in the brain known...

Some people feel compelled to pet every furry animal they see on the street, while others jump at the mere sight of a shark or snake on the television screen. No matter what your response is to animals, it may be thanks to a specific part of your brain that is hardwired to rapidly detect creatures of the nonhuman kind. In fact, researchers from the California Institute of Technology (Caltech) and UCLA report that neurons throughout the amygdala–a center in the brain known for processing...

When a male rat senses the presence of a fetching female rat, a certain region of his brain lights up with neural activity, in anticipation of romance. Now Stanford University researchers have discovered that in male rats infected with the parasite Toxoplasma, the same region responds just as strongly to the odor of cat urine. Is it time to dim the lights and cue the Rachmaninoff for some cross-species canoodling? "Well, we see activity in the pathway that normally controls how male...

A press release from PLoS ONE New research shows how a brain parasite can manipulate rodent fear responses for the parasite's own benefit. The study, authored by Patrick House and Dr. Robert Sapolsky of Stanford University and released this week in PloS One, addressed how the single-celled parasite Toxoplasma gondii makes infected rodents more likely to spend time near cat odors. The study finds Toxoplasma-infected male rats have altered activation in brain regions involved in fear and...

MRI scans show their children have an enlarged amygdala Researchers think that brains are sensitive to the quality of child care, according to a study that was directed by Dr. Sonia Lupien and her colleagues from the University of Montreal published today in the Proceedings of the National Academy of Sciences. The scientists worked with ten year old children whose mothers exhibited symptoms of depression throughout their lives, and discovered that the children's amygdala, a part of the brain...

Researchers from the University of Bonn find decrease in activity of the brain's 'fear center' The study, which was supported by the German Research Foundation, brought together scientists from the Universities of Bonn and Köln, as well as from the Charit© in Berlin. 28 younger persons who had been smoking for quite a number of years and an equal number of non-smokers participated in this study. Each of the subjects was shown photos of happy, fearful and neutral faces while their...

How easy is it to falsify memory? New research at the Weizmann Institute shows that a bit of social pressure may be all that is needed. The study reveals a unique pattern of brain activity when false memories are formed "“ one that hints at a surprising connection between our social selves and memory. The experiment, conducted by Prof. Yadin Dudai and research student Micah Edelson of the Institute's Neurobiology Department with Prof. Raymond Dolan and Dr. Tali Sharot of University...

Picture a menacing drill sergeant, a gory slaughterhouse, a devastating scene of a natural disaster. Researchers at Washington University in St. Louis have found that viewing such emotion-laden images immediately after taking a test actually enhances people's retention of the tested material. The data the researchers gathered in recent studies are the first to show that negative arousal following successful retrieval of information enhances later recall of that information. The finding is...

Research shows morally laden scenarios get different responses from people of different ages.Moral responses change as people age says a new study from the University of Chicago.Both preschool children and adults distinguish between damage done either intentionally or accidently when assessing whether a perpetrator has done something wrong, said study author Jean Decety. But, adults are much less likely than children to think someone should be punished for damaging an object, for example,...

    * Individuals with fetal alcohol spectrum disorders (FASD) have numerous motor, behavioral, and cognitive difficulties.    * Deep gray matter, the brain's "relay" stations, may be key to understanding alcohol-related brain injuries.    * Recent findings show significant volume reductions in deep gray matter structures of those with FASD. Individuals with fetal alcohol spectrum disorders (FASD) have numerous motor, behavioral, and cognitive...
