Popis: Synaptic loss may disturb the excitatory to inhibitory balance (E/I ratio) in circuits vulnerable in Alzheimer’s disease (AD). The authors find reduced synaptic levels of PSD-95 and gephyrin and show that individuals with AD exhibit a pro-excitatory shift of postsynaptic densities and the electrophysiological synaptic E/I ratio in the parietal cortex.
