Hippocampal theta, gamma, and theta-gamma coupling: effects of aging, environmental change, and cholinergic activation.

Abstract

Hippocampal theta and gamma oscillations coordinate the timing of multiple inputs to hippocampal neurons and have been linked to information processing and the dynamics of encoding and retrieval. One major influence on hippocampal rhythmicity is from cholinergic afferents. In both humans and rodents, aging is linked to impairments in hippocampus-dependent… (More)
