Altered auditory-evoked potentials in mice carrying mutated human amyloid precursor protein and presenilin-1 transgenes.

Abstract excerpt

Transgenic mice carrying human APPswe and PS1-A264E transgenes (A/P mice) have elevated levels of the highly fibrillogenic amyloid Abeta(1-42) (Abeta) and develop amyloid plaques around the age of 9 months. Our aim was to find whether the gradual accumulation of Abeta in these mice can be detected with long-term recording of auditory-evoked potentials. The A/P double-mutant mice had impaired auditory gating and a...
