Nerve Cells Help Our Brain Make Sense Of Our Senses
2011-11-21 10:56:22

[ Watch the Video ] The human brain is bombarded with a cacophony of information from the eyes, ears, nose, mouth and skin. Now a team of scientists at the University of Rochester, Washington University in St. Louis, and Baylor College of Medicine has unraveled how the brain manages to process those complex, rapidly changing, and often conflicting sensory signals to make sense of our world. The answer lies in a relatively simple computation performed by single nerve cells, an operation...

Researchers at the University of Tampere and the Aalto University, Finland, have shown that the perception of nude bodies is boosted at an early stage of visual processing. The research was funded by the Academy of Finland. Most people like to look at pictures of nude or scantily clad human bodies. Looking at nude bodies is sexually arousing, and a nude human body is a classic subject in art. Advertising, too, has harnessed half-clothed models to evoke positive images about the products...

Brain imaging experiments uncouple two apparently intimately connected mental processes In everyday life, attention and awareness appear tightly interwoven. Attending to the scissors on the right side of your desk, you become aware of their attributes, for example the red handles. Vice versa, the red handles could attract your attention to the scissors. However, a number of behavioural observations have recently led scientists to postulate that attention and awareness are fundamentally...

When we gaze at a shape and then the shape disappears, a strange thing happens: We see an afterimage in the complementary color. Now a Japanese study has observed for the first time an equally strange illusion: The afterimage appears in a “complementary” shape–circles as hexagons, and vice-versa. “The finding suggests that the afterimage is formed in the brain, not in the eye,” the author, Hiroyuki Ito of Kyushu University, wrote in an email. More...

Caroline DeLong, an assistant professor of psychology at Rochester Institute of Technology, is researching object discrimination in goldfish and echolocation in dolphins to bring scientists closer to unlocking the mysteries of animal perception and cognition. (PRWEB) October 25, 2011 The fictitious storybook character Dr. Doolittle was known for talking with animals. Caroline DeLong, an assistant professor of psychology at Rochester Institute of Technology, is a real-life Doolittle whose...

Groundbreaking Brain Scanner Reconstructs Visual Experiences
2011-09-23 05:13:47

   Scientists at the University of California, Berkeley, have created a groundbreaking brain-imaging process that allows them to 'see' moving images inside people's minds.  The researchers had volunteers watch movie clips as a scanner watched their brains. Then, using this brain activity, a computer made a rough reconstruction of what the study participants viewed. As the test subjects thought of a video, the scientists were able to 'see' it on screen, the researchers...

After more than three decades of research, University of Pennsylvania veterinarians and vision-research scientists, with associates at Cornell University, have identified a gene responsible for a blindness-inducing disease that afflicts dogs. In the process, the Penn scientists may have discovered clues about how retinal cells, and perhaps even neurons, can be regenerated. The research was conducted by Gustavo D. Aguirre, William A. Beltran, Agnes I. Berta and Sem Genini of Penn's School...

New research in the FASEB Journal provides insight into the molecular basis of one form of retinal degeneration, Enhanced S-Cone Syndrome also known as Goldman-Favre Syndrome A new research report published in The FASEB Journal (https://www.fasebj.org) will help ophthalmologists and scientists better understand a rare genetic disease that causes increased susceptibility to blue light, night blindness, and decreased vision called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome. In the...

How the brain controls impulsive behavior may be significantly different than psychologists have thought for the last 40 years. That is the unexpected conclusion of a study by an international team of neuroscientists published in the Aug. 31 issue of the Journal of Neuroscience. Impulse control is an important aspect of the brain's executive functions — the procedures that it uses to control its own activity. Problems with impulse control are involved in ADHD and a number of other...
