Couldwell, William T. | Irving S. Cooper (1922-1985): a pioneer in functional neurosurgery | Irving S. Cooper (1922-1985), the son of a salesman, worked his way through high school, college, and medical school to become one of the pioneers in functional neurosurgery. He developed several novel techniques for the surgical management of Parkinson's disease and other crippling movement disord... | Functional neurosurgery; Cryosurgery; Dystonia; Movement disorder; Parkinson's disease; Thalamotomy; Tremor; Neurosurgical history | 1998 |

Lefohn, Aaron; Kniss, Joe; Hansen, Charles D.; Whitaker, Ross T. | Interactive deformation and visualization of level set surfaces using graphics hardware | Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization for applications such as segmentation, surface process- ing, and surface reconstruction. Their usefulness has been limited, however, by two problems. First, 3D level sets are relativel... | Interactive deformation; Deformable isosurfaces; Level-set methods | 2003-04-16 |

Lefohn, Aaron; Cates, Joshua E.; Whitaker, Ross T. | Interactive, GPU-based level sets for 3D brain tumor segmentation | While level sets have demonstrated a great potential for 3D medical image seg- mentation, their usefulness has been limited by two problems. First, 3D level sets are relatively slow to compute. Second, their formulation usually entails several free parameters which can be very difficult to correc... | Level sets; Medical imaging; 3D brain tumor segmentation | 2003-04-16 |

Jorgensen, Erik | Neural plasticity | Neural plasticity refers to functional changes in the nervous system and therefore encompasses a range of phenomena from changes at synapses observed on a microscopic scale to changes in behavior observed in the whole animal. These diverse phenomena are related since changes in synapses are believ... | Synapses; Nervous System; Development | 1997 |

Gouw, Launce G.; McKenna, Catherine K.; Digre, Kathleen B.; Placek, Louis J. | Analysis of the dynamic mutation in the SCA7 gene shows marked parental effects on CAG repeat transmission. | The gene for spinocerebellar ataxia 7 (SCA7) includes a transcribed, translated CAG tract that is expanded in SCA7 patients. We have determined expansions in 73 individuals from 17 SCA7 kindreds and compared them with repeat lengths of 180 unaffected individuals. Subjects with abnormal expansions co... | Genetics; Biosynthesis; SCA7 Gene | 1998-03-07 |

Zhang, Kang; Yang, Zhenglin; Jiang, Li | Mutations in LRP5 or FZD4 underlie the common familial exudative vitreoretinopathy locus on chromosome 11q | Familial exudative vitreoretinopathy (FEVR) is an inherited blinding disorder of the retinal vascular system. Autosomal dominant FEVR is genetically heterogeneous, but its principal locus, EVR1, is on chromosome 11q13-q23. The gene encoding the Wnt receptor frizzled-4 (FZD4) was recently reported ... | Familial exudative vitreoretinopathy; FEVR; Inherited blinding disorders | 2004 |

Frederick, Jeanne M. | The prenyl-binding protein PrBP/δ: A chaperone participating in intracellular trafficking | Expressed ubiquitously, PrBP/d functions as chaperone/co-factor in the transport of a subset of prenylated proteins. PrBP/d features an immunoglobulin-like b-sandwich fold for lipid binding, and interacts with diverse partners. PrBP/d binds both C-terminal C15 and C20 prenyl side chains of phototran... | 2012-01-01 | |

Jorgensen, Erik | Caenorhabditis elegans gene unc-25 encodes glutamic acid decarboxylase and is required for synaptic transmission but not synaptic development | The neurotransmitter GABA has been proposed to play a role during nervous system development. We show that the Caenorhabditis elegans gene unc-25 encodes glutamic acid decarboxylase (GAD), the GABA biosynthetic enzyme. unc-25 is expressed specifically in GABAergic neurons. Null mutations in unc-25... | 1999 | |
