If the neurotoxin reaches the lateral hypothalamus, the rat may stop eating, and if the neurotoxin reaches the third ventricle, the rat usually dies during surgery. Although the precise cause has not been investigated rigorously, death may be owing to destruction of the vegetative centers in the floor of the fourth ventricle. The survival rate for this surgery can be greatly enhanced if the lesions are produced in two stages. In the first stage, the excitotoxin is injected into the basal forebrain in one or two places unilaterally.

Neurofibrillary tangles usually develop in frontal and occipital cortex; the concentration of aluminum directly correlates with the number of neurofibrillary tangles in each affected region. Rabbits are administered aluminum salts by subcutaneous injections (usually into a shaved area of the back) 5 times weekly Wenk for 4 wk (25-400 urnoles/kg injection). , 1982). 22 urn filters) under sterile conditions. The LD 50 for aluminum using this exposure route is about 1600 urnoles/kg/injection. ICV injections of aluminum produce neurofibrillary tangles in the brainstem, spinal cord, hippocampus, and cortex, whereas systemic injections produce neurofibrillary tangles in many cortical regions, but not in the hippocampus.
