Title:  “How degenerative dementias affect the cortex in humans” 

Abstract:

A number of different histopathologies underpin the degenerative dementias. The relationship is complex: sometimes the same pathology can affect the brain in different topographical distributions although the pattern is never completely random. Other times, completely different pathologies can cause precisely the same pattern of degeneration—and therefore the same clinical phenotype. No-one knows why this is the case, but I will argue that these similarities and differences are likely indicating something fundamental about why these diseases occur. I shall also show that there are significant risks of drawing spurious conclusions by: failing to appreciate the limitations of the imaging techniques we use to study the brain; of starting from overly simplistic assumptions about pathological states; and of being overly wedded to pet hypotheses.

 

 

About Neuroscience Seminars

Neuroscience seminars at the QBI play a major role in the advancement of neuroscience in the Asia-Pacific region. The primary goal of these seminars is to promote excellence in neuroscience through the exchange of ideas, establishing new collaborations and augmenting partnerships already in place.

While seminars in the QBI Auditorium have been suspended due to COVID-19, we will still be holding seminars via Zoom. The days and times of these seminars will vary depending on the time zone of the speaker. Please see each seminar listed below for details.
