Electronic Thesis and Dissertation Repository
Acetylcholine (Ach) has a fundamental role in cortical activation. The activation of the hippocampus, a cortex implicated in cognitive and sensorimotor functions, is characterized by an increase in power and frequency of oscillations in the theta (4-10 Hz) and gamma (30-100 Hz) frequency range. We studied hippocampal activation in two mutant mouse lines with deficiency in cholinergic functionality: VAChT KDHET (HET), and VAChTNkx2.1-Cre-flox/flox (KO). We hypothesized that the mutant mice, relative to wild-type (WT) mice, will manifest abnormal theta and gamma oscillations during different behaviors, and in response to muscarinic cholinergic antagonist scopolamine hydrochloride and to the NMDA …
