Long-range synchronization of gamma and beta oscillations and the plasticity of excitatory and inhibitory synapses: a network model.

The ability of oscillating networks to synchronize despite significant separation in space, and thus time, is of biological significance, given that human gamma activity can synchronize over distances of several millimeters to centimeters during ...

Reconstruction of speech from whispers.

This paper investigates a method for the real-time reconstruction of normal speech from whispers. This system could be used by aphonic individuals as a voice prosthesis. It could also provide improved verbal communication when normal speech is not ...

Simulated medical learning environments on the Internet.

Learning anatomy and surgical procedures requires both a conceptual understanding of three-dimensional anatomy and a hands-on manipulation of tools and tissue. Such virtual resources are not available widely, are expensive, and may be culturally ...

Identifying a differential equation for lip motion.

A second order homogeneous differential equation is fitted to lip trajectories during speech at fast, normal, and slow speaking rates. The objective is to characterize lip motion in terms of biomechanical parameters such as stiffness, damping, and ...

A unified mechanism for spontaneous-rate and first-spike timing in the auditory nerve.

Recent physiological experiments have provided detailed descriptions of the properties of first-spike latency and variability in auditory cortex and nerve in response to pure tones with different envelopes. The envelope-dependence of first-spike timing ...

An integrative review of computer-based simulation in the education process.

The purpose of this study was to review quantitative studies related to computer-based simulation and healthcare education and determine the effect of simulation on education and learning. A total of 513 references were retrieved, but only 9 quantitative ...

How to avoid spurious cluster validation? A methodological investigation on simulated and fMRI data.

This paper presents an evaluation of a common approach that has been considered as a promising option for exploratory fMRI data analyses. The approach includes two stages: creating from the data a sequence of partitions with increasing number of subsets ...

An fMRI-constrained MEG source analysis with procedures for dividing and grouping activation.

To analyze neural activity using magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI), we developed a method for fixing equivalent current dipoles of MEG in activation areas of fMRI. It includes a procedure for dividing large ...

How virtual reality may enhance training in obstetrics and gynecology.

OBJECTIVE: Contemporary training in obstetrics and gynecology is aimed at the acquisition of a complex set of skills oriented to both the technical and personal aspects of patient care. The ability to create clinical simulations through virtual reality ...
