Detecting dementia’s damaging effects before it’s too late

Using MEG neuroimaging, researchers identify abnormalities in functional activity in brain regions which look structurally normal on conventional MRI scans. The findings could help with early detection of primary progressive aphasia.

Navigating ‘Neuralville’: Virtual town helps map brain functions

Combining neuroimaging and a constructed virtual reality town, researchers found the brain uses three different systems to perceive environment. One system allows us to recognize a place, another helps navigate through that location, and the third helps navigate from one place to another. The parahippocampal place area (PPA) helps encode location recognition, while the retrosplenial complex allows for mentally mapping the locations of specific places.

Study Reveals Trade-off Between Complex Words and Complex Grammar in Sentences

People with primary progressive aphasia who have difficulty producing complex words as a result of their condition, compensate by stringing together a sequence of simpler words to convey the idea they wish to express.

Speech-disrupting brain disease reflects patients’ native tongue

Language difficulties associated with primary progressive aphasia differ depending on a person's native language, a new study reports. Native English speakers with PPA have more trouble pronouncing words, while those who speak Italian had fewer pronunciation problems but tend to produce shorter and grammatically simpler sentences.
