Alzheimer's disease pathology degrades an NMDA receptor-dependent spontaneous activity pattern in cortico-hippocampal circuits

2 months 2 weeks ago
Memory-based cognition relies on the integrity of cortico-hippocampal circuits, which are compromised in Alzheimer's disease (AD) as β-amyloid (Aβ) and tau accumulate. However, the mechanisms linking this pathology to circuit dysfunction remain unclear. In mouse models, using in vivo two-photon and Neuropixels recordings, we show that Aβ-tau pathology promotes both region- and layer-specific impairments, involving reduced burst firing in superficial cortical layers and CA1 and reduced mean...
