Studies on a possible functional coupling between presynaptic acetylcholinesterase and high-affinity choline uptake in the rat brain.

abstract：:Hyperexcitability of the hippocampus is a commonly observed phenomenon in the years preceding a diagnosis of Alzheimer's disease (AD). Our previous work suggests a dysregulation in glutamate neurotransmission may mediate this hyperexcitability, and glutamate dysregulation correlates with cognitive deficits in the rTg(...
