Rodent olfaction and the chemistry of instinct The mechanics of instinctive behavior are mysterious. Even something as simple as the question of how a mouse can use its powerful sense of smell to detect and evade predators, including species it has never met before, has been almost totally unknown at the molecular level until now. David Ferrero and Stephen Liberles, neuroscientists at Harvard Medical School, have discovered a single compound found in high concentrations in the urine of...

Research published this week in the journal Nature Communications shows that a light-sensitive protein found in the human eye can act as a "compass" in the magnetic field when implanted into the eyes of Drosophila (flies). The study showed that without their natural "magneto reception" protein, flies do not respond to a magnetic field. But after replacing the protein with a human version of the protein, their ability was restored. For migratory birds and some other animals, the ability to...

A team of scientists, led by researchers at the University of California, San Diego School of Medicine, have uncovered a novel mechanism regulating gene expression and transcription linked to Spinocerebellar ataxia 7, an inherited neurological disorder. The discovery promises to have broad ramifications, suggesting that abundant non-coding transcripts of ribonucleic acid (RNA) may be key players in neurological development and function, and could be powerful targets for future clinical...

By taking advantage of a "body swap" illusion, researchers have captured the brain regions involved in one of the most fundamental aspects of self-awareness: how we recognize our bodies as our own, distinct from others and from the outside world. That self-perception is traced to specialized multisensory neurons in various parts of the brain that integrate different sensory inputs across all body parts into a unified view of the body. The findings, reported online on June 16 in Current...

(Ivanhoe Newswire) -- Everybody has heard about echolocation in bats and dolphins. These creatures emit bursts of sounds and listen to the echoes that bounce back to detect objects in their environment. What is less well known is that people can echolocate, too. In fact, there are blind people who have learned to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these people are so adept at echolocation that they can use this...

Our brain's understanding of spatial awareness is not triggered by sight alone, scientists have found, in a development that could help design technology for the visually impaired Our brain's understanding of spatial awareness is not triggered by sight alone, scientists have found, in a development that could help design technology for the visually impaired. Researchers at the University of Edinburgh have found that our brain can use other senses "“ such as touch "“ to help us...

Echolocation in bats and dolphins is well known. Bursts of sounds are created and the echoes that bounce back are used to locate and detect objects in the environment. What is less well known is that people can echolocate, too. Blind people have been known to learn to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these people are so adept at echolocation that they can use this skill to go mountain biking, play basketball,...

New research shows that itch receptors work through pain receptors on sensory neurons A new study of itch adds to growing evidence that the chemical signals that make us want to scratch are the same signals that make us wince in pain. The interactions between itch and pain are only partly understood, said itch and pain researcher Diana Bautista, an assistant professor of molecular and cell biology at the University of California, Berkeley. The skin contains some nerve cells that respond only...
