Angelucci, Alessandra | Multiple components of surround modulation in primary visual cortex: Multiple neural circuits with multiple functions? | The responses of neurons in primary visual cortex (V1) to stimulation of their receptive field (RF) are modulated by stimuli in the RF surround. This modulation is suppressive when the stimuli in the RF and surround are of similar orientation, but less suppressive or facilitatory when they are cross... | | 2014-01-01 |

Normann, Richard A. | Acute human brain responses to intracortical microelectrode arrays: challenges and future prospects | The emerging field of neuroprosthetics is focused on the development of new therapeutic interventions that will be able to restore some lost neural function by selective electrical stimulation or by harnessing activity recorded from populations of neurons.

Frederick, Jeanne M. | Inactivity of human β,β-carotene-9′, 10-′dioxygenase (BCO2) underlies retinal accumulation of the human macular carotenoid pigment | The macula of the primate retina uniquely concentrates high amounts of the xanthophyll carotenoids lutein, zeaxanthin, and meso-zeaxanthin, but the underlying biochemical mechanisms for this spatial- and species-specific localization have not been fully elucidated. For example, despite abundant reti... | | 2014-01-01 |

Frederick, Jeanne M. | Centrin 2 is required for mouse olfactory ciliary trafficking and development of ependymal cilia planar polarity | Centrins are ancient calmodulin-related Ca2-binding proteins associated with basal bodies. In lower eukaryotes, Centrin2 (CETN2) is required for basal body replication and positioning, although its function in mammals is undefined. We generated a germline CETN2 knock-out (KO) mouse presenting with s... | | 2014-01-01 |

Frederick, Jeanne M. | RNA interference gene therapy in dominant retinitis pigmentosa and cone-rod dystrophy mouse models caused by GCAP1 mutations | RNA interference (RNAi) knockdown is an efficacious therapeutic strategy for silencing genes causative for dominant retinal dystrophies. To test this, we used self-complementry (sc) AAV2/8 vector to develop an RNAi-based therapy in two dominant retinal degeneration mouse models. The allele-specific ... | | 2014-01-01 |

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 |

Frederick, Jeanne M. | Uncoordinated (UNC)119: Coordinating the trafficking of myristoylated proteins | The mechanism by which myristoylated proteins are targeted to specific subcellular membrane compartments is poorly understood. Two novel acyl-binding proteins, UNC119A and UNC119B, have been shown recently to function as chaperones/co-factors in the transport of myristoylated G protein a-subunits an... | | 2012-01-01 |

Fuhrmann, Sabine | Extraocular ectoderm triggers dorsal retinal fate during optic vesicle evagination in zebrafish | Dorsal retinal fate is established early in eye development, via expression of spatially restricted dorsal‐specific transcription factors in the optic vesicle; yet the events leading to initiation of dorsal fate are not clear. We hypothesized that induction of dorsal fate would require an extraocu... | | 2012-01-01 |
