Summary: Nicotinic acetylcholine receptors (nAChR) are involved in a wide range of processes in the central nervous system, many having to do with higher cognitive functions. In order to better understand how these receptors mediate attentional performance, the authors investigated glutamate release under varying conditions. In one series of experiments rats received a 160-ng injection of 192-IgG-SAP (Cat. #IT-01) into the right medial prefrontal cortex. The resulting decrease in glutamate release after the cholinergic lesion adds to the data indicating that positive modulation of nAChR may help alleviate attentional impairments caused by some brain disorders.
