Objective: To assess the effects of varying stimulation patterns and duration on learning in a dementia rat model.
Summary: Deep brain stimulation (DBS) of nucleus basalis of Meynert (NBM) has been considered a potential treatment for dementia, but more study is needed to determine the ideal parameters for NBM stimulation. 192-IgG-SAP (Cat. IT-01) was used to lesion cholinergic neurons of rats creating a rat model of dementia upon which NBM deep brain stimulation could be tested. The desired destruction of neurons was 70-80% cholinergic population lesioned, which through a panel of concentrations was determined to be a 0.50 μg dose. The rat models of dementia were then tested for ideal type and duration of deep brain stimulation to improve operant learning test performance.
Usage: 192-IgG-SAP was bilaterally injected in the NBM in the following amounts: 0.00 (control), 0.15, 0.30, 0.50, and 0.75 μg in 0.5 μl PBS.
