A study of brain imaging reveals how neural responses to different types of music really affect the emotion regulation of persons - especially in men, who process negative feelings with music and react negatively to aggressive and sad music, according to the findings.

The JAMA Neurology feature "Images in Neurology" features the case of a 25-year-old right-handed physical education student who was buried by an avalanche during a ski tour and endured 15 minutes of hypoxia (oxygen deficiency). He developed involuntary myoclonic jerking (brief, involuntary twitching of muscles) of the mouth induced by talking and of the legs by walking. Weeks later when he was trying to solve Sudoku puzzles he developed clonic seizures (rapid contractions of muscles) of the left arm. The seizures stopped when the Sudoku puzzle was discontinued. Berend Feddersen, M.D., Ph.D., of the University of Munich, Germany, and coauthors suggest oxygen deficiency most likely caused some damage to the brain.

Our ability to learn, move, and sense our world comes from the neurons in our brain. The information moves through our brain between neurons that are linked together by tens of trillions of tiny structures called synapses.

Although tiny, synapses are not simple and must be precisely organized to function properly. Indeed, diseases like autism and Alzheimer's are increasingly linked to defects in the organization and number of these tiny structures. Now researchers at Thomas Jefferson University have found a new way in which synapses organization is controlled, which could eventually lead to better treatments for neurological diseases.

In nutrition, the saying goes, 'in the old days you had to be rich to be fat, now you have to be rich to be thin.' 

We have a biological mandate to try and ride out food booms and busts by consuming as many calories as we can, when we can. Rich people can take that out of their hands by paying for people to tell them to exercise and what not to eat and so they won't get gout like they once did. Poor people, with less disposable income, will shop for calorically-dense foods. 

Try to remember a phone number, and you're using what's called your sequential memory. This kind of memory, in which your mind processes a sequence of numbers, events, or ideas, underlies how people think, perceive, and interact as social beings. 

"In our life, all of our behaviors and our process of thinking is sequential in time," said Mikhail Rabinovich, a physicist and neurocognitive scientist at the University of California, San Diego.

Researchers have made a breakthrough in explaining how an incurable type of blood cancer develops from an often symptom-less prior blood disorder. All patients diagnosed with myeloma, a cancer of the blood-producing bone marrow, first develop a relatively benign condition called 'monoclonal gammopathy of undetermined significance' or 'MGUS'. 

MGUS is fairly common in the older population and only progresses to cancer in approximately one in 100 cases. However, currently there is no way of accurately predicting which patients with MGUS are likely to go on to get myeloma.
