Abstract

The third ventricle region houses several neuroanatomical structures that are primary components of the human memory system, and provides pathways through which these brain regions communicate with critical regions of the frontal and medial temporal lobes. Archival data was obtained for 42 children with cerebellar or third ventricle tumors, and was examined for tumor and treatment related confounds. Children with third ventricle tumors were hypothesized to exhibit; 1) better performance on a measure of auditory attention, 2) greater impairment in learning across trials, 3) greater memory loss over a 20-minute delay, and 4) greater impairment across delayed memory tests than the cerebellar group. Children with third ventricle tumors demonstrated significantly better auditory attention, but greater impairments in verbal learning, and greater verbal memory loss following a 20-minute delay. In contrast, children with third ventricle tumors did not demonstrate significantly greater memory impairments across long delay memory tests.
