Cholinergic modulation targeting medial prefrontal cortex leads to behavior deficit in interval timing task

Zhang Q, De Corte B, Jung D, Kim Y, Geerling J, Narayanan N (2018) Cholinergic modulation targeting medial prefrontal cortex leads to behavior deficit in interval timing task. Neurology 90 (15 Supplement):P5.195.

Objective: To determine the effect of cholinergic lesion targeting medial prefrontal cortex on interval timing behavior.

Summary: Mice receiving medial prefrontal mu-p75-saporin injection performed poorly compared to control mice in interval timing task. Cholinergic lesion targeting medial prefrontal cortex caused interval timing behavior deficit in wild type mice.

Usage: mu-p75-SAP, a toxin targeting cholinergic neurons, into the bilateral medial prefrontal cortical regions of wild type mice pre-trained in interval timing task. Control mice (also pre-trained in interval timing task, n=8) received stereotactic injection of Rabbit IgG-SAP.
