Romantic Rejection Stimulates Key Brain Areas
Released July 6, 2010 -- The pain and anguish of rejection by a romantic partner may be the result of activity in parts of the brain associated with motivation, reward and addiction craving. A new research effort could explain why feelings related to romantic rejection can be hard to control and provide insight into extreme behaviors associated with rejection. Those who are coping with a romantic rejection may be fighting against a strong survival system that appears to be the basis of many addictions. The data help to explain why the beloved is so difficult to give up.
Have Brain Fatigue? A Bout of Exercise May be the Cure
Released September 16, 2011 - Researchers have discovered that regular exercise increases mitochondria in brain cells, a potential cause for exercise’s beneficial mental effects.
Is There a Central Brain Area for Hearing Melodies and Speech Cues?
Released November 28, 2011 - The perceptual feature of sound known as pitch is fundamental to human hearing, allowing us to enjoy the melodies and harmonies of music and recognize the inflection of speech. Previous studies have suggested that a particular hotspot in the brain might be responsible for perceiving pitch. However, auditory neuroscientists are still hotly debating whether this “pitch center” actually exists. A new review article discusses a recent study claiming that this pitch center may not exist after all, or alternatively, may not be located where previous research has suggested.
Working Memory and the Brain
Released February 6, 2012 - Work published in the Journal of Neurophysiology may explain why people can hold visual information in high detail in their working memory. Using functional neuroimaging, investigators found that visual working memory follows a more general pattern of brain activity than visual perception and relies on concerted action of specialized areas in the rear of the brain and control areas in the front of the brain, which were activated regardless of what the participants viewed.
Researchers Block Damage to Fetal Brain Following Maternal Alcohol Consumption
Released August 11, 2008 - In a study on fetal alcohol syndrome, researchers were able to prevent the damage that alcohol causes to cells in a key area of the fetal brain by blocking acid sensitive potassium channels and preventing the acidic environment that alcohol produces. The cerebellum, the portion of the brain that is responsible for balance and muscle coordination, is particularly vulnerable to injury from alcohol during development.
