SfN 2026: Neural Circuit Research in Neurodegeneration
Overview
Neural circuit dysfunction is increasingly recognized as a central mechanism in neurodegenerative diseases, bridging molecular pathology with clinical symptoms. At SfN Neuroscience 2026, the neurodegeneration sessions will feature extensive coverage of circuit-level alterations in Alzheimer's disease (AD), Parkinson's disease (PD), and related disorders. This page catalogs presentations on synaptic dysfunction, circuit remodeling, and network-level changes across the neurodegenerative disease spectrum[@society2026].
This research domain represents a critical translational bridge—understanding how protein aggregates disrupt neural networks provides insight into early cognitive and motor symptoms, while identifying novel therapeutic targets for circuit restoration.
Alzheimer's Disease: Circuit Dysfunction and Network Decline
Synaptic Pathology in AD
The synaptic compartment is a primary target in Alzheimer's disease, with synaptic loss correlating strongest with cognitive decline. SfN 2026 will feature extensive coverage of:
Amyloid-Beta Synaptic Toxicity
Oligomeric species as the most synaptotoxic forms
NMDA receptor dysfunction and excitotoxicity
AMPA receptor trafficking abnormalities
Synaptic scaffolding protein disruption (PSD95, Homer)
Presynaptic vesicle cycle impairment
Tau-Mediated Synaptic Dysfunction
...
