During early stages of Alzheimer’s disease (AD) gradual accumulation and aggregation of Aβ oligomers (AβO) occurs prior to cognitive decline. This preclinical stage of AD is further characterized by synaptic dysfunction and network hyperexcitability. We recently discovered that 24-hour treatment of AβO to hippocampal slices impairs release at GABAergic synapses, most prominently at dendritic inhibitory synapses. This suggests that inhibitory synapses are particularly vulnerable to AβO toxicity.We currently use advanced imaging approaches in vitro to further investigate the mechanisms that
