“sparse” temporal sampling in auditory fMRI
The use of functional magnetic resonance imaging (fMRI) to explore central auditory function may be compromised by the intense bursts of stray acoustic noise produced by the scanner whenever theExpand

Spectral and temporal processing in human auditory cortex.
Hierarchical processing suggests that spectrally and temporally complex stimuli will evoke more activation than do simple stimuli, particularly in non-primary auditory fields. This hypothesis wasExpand

Detection in noise by spectro-temporal pattern analysis.
Detectability of a 400-ms, 1000-Hz pure-tone signal was examined in bandlimited noise where different spectral regions were given similar waveform envelope characteristics. As expected, in randomExpand

Functional magnetic resonance imaging measurements of sound-level encoding in the absence of background scanner noise.
Effects of sound level on auditory cortical activation are seen in neuroimaging data. However, factors such as the cortical response to the intense ambient scanner noise and to the bandwidth of theExpand

The clinical assessment of obscure auditory dysfunction--1. Auditory and psychological factors.
We define obscure auditory dysfunction (OAD) as the clinical presentation of reported difficulty understanding speech in the presence of noise accompanied by clinically "normal" hearing thresholds,Expand

Ploidy of lymphoblasts is the strongest predictor of treatment outcome in B-progenitor cell acute lymphoblastic leukemia of childhood: a Pediatric Oncology Group study.
PURPOSE Using the technique of recursive partitioning and amalgamation analysis with verification, the Pediatric Oncology Group (POG) investigated the independent prognostic significance ofExpand

Perceiving vowels from uniform spectra: Phonetic exploration of an auditory aftereffect
A carefully spoken vowel can generally be identified from the pattern of peaks and valleys in the envelope of its short-term power spectrum, and such patterning is usually necessary for theExpand

Can Meaningful Effective Connectivities Be Obtained between Auditory Cortical Regions?
SEM of auditory fMRI data is made difficult by the necessary sparse temporal sampling of the time series (to avoid contamination of auditory activation by the response to scanner noise) and by the paucity of well-defined anatomical information to constrain the functional model. Expand

Pitch as a voicing cue.
The pitch change at the onset of voicing after a period of articulatory closure for a consonant reflects the state of the glottis during that closure. In initial position, a low rising pitchExpand
