Here we describe an Aβ‐mediated deleterious synaptic mechanism that modifies the threshold for the induction of hippocampal LTP and/or LTD and underlies memory alterations in amyloidosis models. We also propose a potential intervention to prevent such synaptic impairment through G‐protein‐gated inwardly rectifying potassium (GirK) channels activation.
