Two Brain Networks are Activated while Reading, study finds

The neural activity of these patients was measured while reading three forms of sentences: regular sentences; “Jabberwocky” sentences (based on Lewis Carroll’s “Jabberwocky” poem), which use correct grammar and syntax but contain nonsense words, making them meaningless; and lists of words or nonsense words.

When a person reads a sentence, two distinct networks in the brain are activated, working together to integrate the meanings of the individual words to obtain more complex, higher-order meaning, according to a study at UTHealth Houston.

The study, led by Oscar Woolnough, Ph.D., postdoctoral research fellow in the Vivian L...

Addiction Cravings may get their Start Deep in the Right side of the Brain

The source of alcohol craving may be a pea-sized structure deep inside the right side of the brain, according to scientists at the Indiana University School of Medicine. Using two different kinds of advanced brain imaging techniques (PET and fMRI), the researchers compared the results of giving beer drinkers a taste of their favorite beer versus a sports drink. After tasting the beer the participants reported increased desire to drink beer, whereas the sports drink did not provoke as much desire for beer. The brain scans showed that the beer flavor induced more activity in both frontal lobes and in the right ventral striatum of the subjects' brains than did the sports drink. Credit: B. Oberlin and D.

If you really want a drink right now, the source of your craving may be a pea-sized structure deep inside the right side of your brain, according to scientists at the Indiana University School of Medicine. Using PET and fMRI, the researchers compared the results of giving beer drinkers a taste of their favorite beer versus a sports drink...
