Lesions of the basal forebrain cholinergic system in mice disrupt idiothetic navigation.

Hamlin AS, Windels F, Boskovic Z, Sah P, Coulson EJ (2013) Lesions of the basal forebrain cholinergic system in mice disrupt idiothetic navigation. PLoS One 8(1):e53472. doi: 10.1371/journal.pone.0053472

Summary: Alzheimer’s disease patients perform poorly on spatial navigation tests requiring either distal cues (allothetic) or body-centered cues (idiothetic). The authors used 0.2 μg bilateral infusions of mu p75-SAP (Cat. #IT-16) into the lateral ventricles of mice to examine the hypothesis that the cholinergic medial septo-hippocampal circuit is important for idiothetic navigation. Rabbit IgG-SAP (Cat. #IT-35) was used as a control. Lesioned animals were similar to controls in contextual fear conditioning, spatial working memory, as well as several other parameters. But exploratory behavior requiring idiothetic signals was very disorganized, indicating that cholinergic cells are vital to idiothetic navigation.
