Scientists aim to learn how serotonin modulates behavior

In popular experience the story of how serotonin modulates the brain might seem simple: pop an antidepressant, serotonin levels go up, mood improves. But neuroscientists acknowledge how little they know about how the neurotransmitter affects circuits and behavior in the incredibly complex human brain. To reveal the basics of how serotonin really works, scientists at MIT’s Picower Institute for Learning and Memory, funded by a new $1.16 million, four-year grant from the National Institutes of Health, will employ a far simpler model: the nematode worm C. elegans..

Language disorders as indicators of the diagnosis and progression of Huntington’s disease

Huntington’s disease is a hereditary neurodegenerative disorder caused by a gene on chromosome 4 that affects a very important area of the brain, the striatum. People are born with the defective gene but symptoms do not appear until the age of 30 or 40. This disease, in addition to motor impairments, cognitive and affective problems, also involves changes in language. A study shows that the first symptoms of the disease are revealed through linguistic changes in spontaneous speech.
