Functional connectivity between the entorhinal and posterior cingulate cortices underpins navigation discrepancies in at-risk Alzheimer's disease
G Coughlan, P Zhukovsky, V Puthusseryppady… - Neurobiology of …, 2020 - Elsevier
Navigation processes that are selectively mediated by functional activity in the entorhinal
cortex may be a marker of preclinical Alzheimer's disease (AD). Here, we tested if a short path …

[HTML][HTML] Machine learning detects altered spatial navigation features in outdoor behaviour of Alzheimer's disease patients
Impairment of navigation is one of the earliest symptoms of Alzheimer’s disease (AD), but to
date studies have involved proxy tests of navigation rather than studies of real life behaviour. …
