Gerig, Guido | Regional gray matter growth, sexual dimorphism, and cerebral asymmetry in the Neonatal Brain | Although there has been recent interest in the study of childhood and adolescent brain development, very little is known about normal brain development in the first few months of life. In older children, there are regional differences in cortical gray matter development, whereas cortical gray and wh... | 2007-01-01 | |

Olson, Randall J.; Coldwell, Karin D.; Compton, Bruce J.; Giddings, John C. | Sedimentation field-flow fractionation: a method for studying particulates in cataractous lens | It is shown that the technique of sedimentation field-flow fractionation (sedimentation [sed] FFF) can be used to determine the particle content and particle size distribution of normal and cataractous lenses. A 31-year-old normal human lens, for example, showed a particle content of 1.5% by weight ... | Fractionation; Cataractous Lens; Particulates | 1984 |

Normann, Richard A.; Shah, Maulik R. | Study of printed spiral coils for neuroprosthetic transcranial telemetry applications | We have explored the use of printed spiral coils (PSC's) for neuroprosthetic transcranial telemetry applications. We fabricated two-dimensional PSC's on a thin (25 microns) polyimide substrate using copper (35 microns) as a conducting material. All the coils had a fixed inner diameter of 1.0 cm.

Mathews, V. John | Neural decoding using a nonlinear generative model for brain-computer interface | Kalman filters have been used to decode neural signals and estimate hand kinematics in many studies. However, most prior work assumes a linear system model, an assumption that is almost certainly violated by neural systems. In this paper, we show that adding nonlinearities to the decoding algorithm ... | 2014-01-01 | |

Mathews, V. John | Subband vector quantization of images using hexagonal filter banks | Abstract Results of psychophysical experiments on human vision conducted in the last three decades indicate that the eye performs a multichannel decomposition of the incident images. This paper presents a subband vector quantization algorithm that employs hexagonal filter banks. The hexagonal filte... | 1992 | |

Angelucci, Alessandra | Experimentally induced retinal projections to the ferret auditory thalamus: development of clustered eye-specific patterns in a novel target | We have examined the relative role of afferents and targets in pattern formation using a novel preparation, in which retinal projections in ferrets are induced to innervate the medial geniculate nucleus (MGN). We find that retinal projections to the MGN are arranged in scattered clusters. Clusters a... | Retina; Ferrets | 1997 |

Gerig, Guido | Semi-automated application for kidney motion correction and filtration analysis in MR renography | Altered renal function commonly affects patients with cirrhosis, a consequence of chronic liver disease. From lowdose contrast material-enhanced magnetic resonance (MR) renography, we can estimate the Glomerular Filtration Rate (GFR), an important parameter to assess renal function. Two-dimensional ... | 2014-01-01 | |

Suchy, Yana | Aberrant functional connectivity of cortico-basal ganglia circuits in major depression | There is considerable evidence of functional abnormalities of the cortico-basal ganglia circuitry in affective disorders. However, it has been unknown whether this represented primary pathology within these circuits or altered activation as a result of aberrant input from other brain regions. The ai... | 2012-01-01 | |

Normann, Richard A.; Jones, Kelly E. | Advanced demultiplexing system for physiological stimulation | A CMOS very large scale integration (VLSI) chip has been designed and built to implement a scheme developed for multiplexing/demultiplexing the signals required to operate an intracortical stimulating electrode array. Because the use of radio telemetry in a proposed system utilizing this chip may im... | Electrode Array; Stimulation; Telemetry; Microelectrodes; Transistors | 1997 |

Angelucci, Alessandra | Role for nitric oxide in the development of the ferret retinogeniculate projection | The ferret retinogeniculate projection segregates into eye-specific layers during the first postnatal week and into ON/OFF sublaminae, which receive inputs from either on-center or off-center retinal ganglion cells, during the third and fourth postnatal weeks. The restriction of retinogeniculate axo... | Enzyme Inhibitors; Visual Pathways; Wheat Germ Agglutinin-Horseradish Peroxidase Conjugate | 1996 |

Friedrich, Frances; Walker, James A. | Effects of parietal injury on covert orienting of visual attention | The cognitive act of shifting attention from one place in the visual field to another can be accomplished covertly without muscular changes. The act can be viewed in terms of three internal mental operations: disengagement of attention from its current focus, moving attention to the target, and enga... | Dominance, Cerebral; Attention; Extinction, Psychological | 1984-07 |

Crandall, Alan S. | Torn posterior capsule: prevention, recognition and management | Modern cataract surgery performed with phacoemulsification allows meticulous intraocular control and minimal incision size, but has the inherent risk of capsular rupture. Therefore, surgeons performing cataract surgery will inevitably face the complication of a torn posterior capsule.

Gerig, Guido | A structural MRI study of human brain development from birth to two years | Brain development in the first 2 years after birth is extremely dynamic and likely plays an important role in neurodevelopmental disorders, including autism and schizophrenia. Knowledge regarding this period is currently quite limited. We studied structural brain development in healthy subjects from... | 2008-01-01 | |

Gerig, Guido | White matter microstructure and atypical visual orienting in 7 month-olds at risk for autism | Objective: The authors sought to determine whether specific patterns of oculo-motor functioning and visual orientingcharacterize 7-month-old infants who later meet criteria for an autism spectrum disorder (ASD) and to identify the neural correlates of these behaviors. Method:Data were collected from... | 2013-01-01 | |
