Dysfunctional Brain Networks Behind Speech-stealing Dementia Revealed

Illustration of the three brain regions associated with speech production and the networks between them that, when broken, lead to speech impairments. Solid orange lines depict significantly lower connectivity between brain regions (in red) in PPA. IFG = Inferior Frontal Gyrus; MTG = Middle Temporal Gyrus; ATL = Anterior Temporal Lobe. PPA = Primary Progressive Aphasia; PPA-G = Nonfluent/agrammatic variant of PPA; PPA-L = Logopenic variant of PPA; PPA-S = Semantic variant of PPA. Credit: Northwestern University

The Next Generation of Hearing Implants Could Be Soft

News

Close to half a million people around the world suffer from a serious hearing impairment. Cochlear implants, whilst useful for some patients, do not help people whose inner ear is damaged or whose auditory nerve does not function properly. Now, researchers have developed a soft variant of an implant that communicates directly with the brainstem.

Microbleeds May Be Sign of Trauma After Minor Brain Injury

News

Using advanced imaging, researchers have uncovered new information regarding traumatic microbleeds, which appear as small, dark lesions on MRI scans after head injury but are typically too small to be detected on CT scans. The findings published in Brain suggest that traumatic microbleeds are a form of injury to brain blood vessels and may predict worse outcomes.
