Objective: To examine whether neurochemical acetylcholine (ACh) contributes to a state of readiness for target detection, by engaging frontoparietal cortical attentional networks independent of modality.
Summary: ACh supported alerting attention to an impending presentation of either visual or olfactory targets. Enhanced stimulus detection was associated with an anticipatory increase in power in the beta oscillation range prior to the target’s appearance within the posterior parietal cortex (PPC) as well as increased synchrony. In beta, this was also detected between the prefrontal cortex and PPC. ACh may act, in a supramodal manner, to prepare frontoparietal cortical attentional networks for target detection.
Usage: The ACh-NBM-lesioned rats received an injection of 0.2 μl of 0.3 μg/μl 192 IgG-SAP
