Newman LA, McGaughy J (2008) Cholinergic deafferentation of prefrontal cortex increases sensitivity to cross-modal distractors during a sustained attention task. J Neurosci 28:2642-2650. doi: 10.1523/JNEUROSCI.5112-07.2008
Summary: The authors injected 5 ng of 192-IgG-SAP (Cat. #IT-01) into the prefrontal cortex of rats to investigate the effect of cholinergic loss on distractors to attentional demand. Where all animals experienced impaired performance in the presence of visual distractions, lesioned animals were more sensitive to auditory distractions. While these results indicate compromised top-down processing, lesioned animals showed improved performance in bottom-up processing, possibly caused by a shift in circuit dynamics after the lesion.
