abstract = {Alzheimer's disease (AD), a progressive neurodegenerative
disorder, is projected to affect over 130 million people
globally by 2050. While extensive efforts have focused on
targeting molecular hallmarks such as amyloid-beta (Aβ)
plaques and tau pathology, network-level dysfunction remains
a critical but underexplored component of AD progression.
Disruptions in hippocampal-cortical (HC) circuit activity
emerge early in AD, compromising memory processing and
cognitive functions. Characterizing these disruptions
requires high-resolution platforms capable of capturing
network-wide spatiotemporal dynamics. To address this, we
implemented a high-density microelectrode array (HD-MEA)
biosensor to assess large-scale electrophysiological
activity in ex vivo hippocampal slices from well-established
APPNL and APPNL-G-F mouse models. Our approach quantifies
hippocampal oscillatory disturbances and examines their
modulation by saffron, a natural compound with reported
neuroprotective properties. Results indicate that
hippocampal network activity is progressively impaired in
APPNL-G-F mice, particularly in sharp-wave ripple (SWR) and
multi-unit activity (MUA) patterns. The HD-MEA platform
provides a scalable tool for investigating AD-associated
network dysfunctions and exploring potential modulatory
interventions.},
