Researchers at Northeastern University in Boston have developed a gene therapy approach that may one day stop Parkinson's disease (PD) in it tracks, preventing disease progression and reversing its symptoms. The novelty of the approach lies in the nasal route of administration and nanoparticles containing a gene capable of rescuing dying neurons in the brain. Parkinson's is a devastating neurodegenerative disorder caused by the death of dopamine neurons in a key motor area of the brain, the...

redOrbit Staff & Wire Reports - Your Universe Online The taste of beer can trigger dopamine release in a person´s brain, even without any effect from the alcohol it contains, researchers from the Indiana University School of Medicine have discovered. The IU researchers recruited 49 men and used a pair of positron emission tomography (PET) scans to test for increased activity of the brain neurotransmitter which has been linked to drinking and other drugs of abuse. The first...

redOrbit Staff & Wire Reports — Your Universe Online Listening to good music can trigger the same reaction in our brains as eating a good meal, taking a psychoactive drug or enjoying an evening of passion, researchers from McGill University in Montreal claim in a new study. The research, which was published in the journal Science, reported the nucleus accumbens is the part of the brain that is most closely associated with the enjoyment a person experiences when listening to a...

Using a miniature electronic device implanted in the brain, scientists have tapped into the internal reward system of mice, prodding neurons to release dopamine, a chemical associated with pleasure. The researchers, at Washington University School of Medicine in St. Louis and the University of Illinois at Urbana-Champaign, developed tiny devices, containing light emitting diodes (LEDs) the size of individual neurons. The devices activate brain cells with light. The scientists report their...

The gene variants weaken the same receptors that some hallucinogenic drugs block New genetic factors predisposing to schizophrenia have been uncovered in five families with several affected relatives. The psychiatric disorder can disrupt thinking, feeling, and acting, and blur the border between reality and imagination. Dr. Debby W. Tsuang, professor of psychiatry and behavioral sciences, and Dr. Marshall S. Horwitz, professor of pathology, both at the University of Washington in...

Brain's Visual Cortex Activates For Reward Even When Stimulus Is Removed
2013-03-22 12:15:13

Alan McStravick for redOrbit.com - Your Universe Online An international collaborative study, conducted by researchers at both KU Leuven and the Harvard Medical School, has attempted to recreate Ivan Pavlov´s famous experiment, but with a twist. Pavlov, you may know, was famous for conducting a study where a stimulus was introduced and the reward for that stimulus was slowly removed, with the aim of observing whether or not a physiological response would continue to be registered...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
