A new anatomical landmark for reliable identification of human area V5/MT: a quantitative analysis of sulcal patterning.

Serge O. Dumoulin, Richard Garth Bittar, +4 authors Alan C. Evans
Cerebral cortex
2000

The location of human area V5 (or MT) has been correlated with the intersection of the ascending limb of the inferior temporal sulcus (ALITS) and the lateral occipital sulcus (LO). This study was… (More)

The "motion-blind" patient: low-level spatial and temporal filters.

Rüdiger Hess, Curtis L Baker, Josef Zihl
The Journal of neuroscience : the official…
1989

The "motion-blind" patient previously described by Zihl et al. (1983) was investigated using standard psychophysical procedures with stimuli whose spatial and temporal properties could be separately… (More)

Central neural mechanisms for detecting second-order motion

Curtis L Baker
Current Opinion in Neurobiology
1999

Single-unit neurophysiology and human psychophysics have begun to reveal distinct neural mechanisms for processing visual stimuli defined by differences in contrast or texture (second-order motion)… (More)

Residual motion perception in a "motion-blind" patient, assessed with limited-lifetime random dot stimuli.

Curtis L Baker, Robert F. Hess, Josef Zihl
The Journal of neuroscience : the official…
1991

A neurological patient (L.M.) suffering a specific loss of visual motion perception (Zihl et al., 1983) due to extrastriate cortical damage was studied using random dot "limited-lifetime" stimuli… (More)

Different parameters control motion perception above and below a critical density

Jane C. Boulton, Curtis L Baker
Vision Research
1993

The maximum displacement for the detection of apparent motion (Dmax) is measured using stimuli made up of Gabor function micro-patterns randomly distributed across the stimulus field. Previous… (More)

Absence of a chromatic linear motion mechanism in human vision

Tatsuya Yoshizawa, Kathy T. Mullen, Curtis L Baker
Vision Research
2000

We have investigated motion mechanisms in central and perifoveal vision using two-frame random Gabor kinematograms with isoluminant red-green or luminance stimuli. In keeping with previous results,… (More)

A cortical locus for the processing of contrast-defined contours

Isabelle Mareschal, Curtis L Baker
Nature Neuroscience
1998

Object boundaries in the natural environment are often defined by changes in luminance; in other cases, however, there may be no difference in average luminance across the boundary, which is instead… (More)

Direction identification thresholds for second-order motion in central and peripheral vision.

Andrew T. Smith, Robert F. Hess, Curtis L Baker
Journal of the Optical Society of America. A…
1994

Evidence bearing on the question of whether first-order and second-order motion are detected by use of the same or different principles has been sought. This question was approached by measuring… (More)

Linear and nonlinear components of human electroretinogram.

Curtis L Baker, Robert F. Hess
Journal of neurophysiology
1984

We compared electroretinographic (ERG) responses to uniform-field and a variety of pattern stimuli using both transient and steady-state analyses. Evidence is provided that for all of these stimuli,… (More)

A nonlinear chromatic motion mechanism

Curtis L Baker, Jane C. Boulton, Kathy T. Mullen
Vision Research
1998

Previous research has demonstrated two categorically distinct mechanisms mediating apparent motion of kinematograms composed of eccentricity-confined, randomly placed Gabor micropatterns: a… (More)
