Saccadic adaptation in Chiari type II malformation.
BACKGROUND Saccadic adaptation corrects errors in saccadic amplitude. Experimentally-induced saccadic adaptation provides a method for studying motor learning. The cerebellum is a major participant in saccadic adaptation. Chiari type II malformation (CII) is a developmental deformity of the cerebellum and brainstem that is associated with spina bifida. We investigated the effects of CII on sacc...

متن کاملPartial rhombencephalosynapsis and Chiari II malformation.
We report a rare case of partial rhombencephalosynapsis coexistent with Chiari II malformation in a 6-year-old girl and discuss the features of these entities on magnetic resonance imaging.
متن کاملMR imaging of Chiari II malformation.
High-field-strength MR imaging was performed in one patient with Chiari III and 19 patients with Chiari II malformations. The MR features were compared with descriptions in the literature and correlated with previously described surgical and postmortem findings and with the results of previous radiologic investigations in this group of patients. Several new observations were apparent from the M...
متن کاملCoexistent holoprosencephaly and Chiari II malformation.
Chiari II malformations and holoprosencephaly have been considered to be brain malformations that differ with respect to teratogenic insult, embryologic mechanism, and morphology. We herein describe coexistent Chiari II malformation and holoprosencephaly that occurred in a viable infant. A review of the literature regarding Chiari II malformations and holoprosencephaly suggests that a disturban...
