WebCholinergic neuron –specific Dyt1 conditional KO (ChKO) mice were produced by crossing ChAT-cre mice with Dyt1 loxP mice (Sciamanna et al., 2012a). These mice had an abnormal striatal cholinergic D2R response with paradoxical excitation to activation and loss of muscarinic M2/M4 receptor inhibitory function.
WebIn a basic summary, cholinergic neurons are always active during wake or rapid eye movement sleep cycles, and are more likely to activate the cerebral cortex to induce the gamma wave and Theta rhythm activities while behaviorally promoting the states of wakefulness and rapid eye movement sleep.
