Size and position invariance of neuronal responses in monkey inferotemporal cortex.
1. Object vision is largely invariant to changes of retinal images of objects in size and position. To reveal neuronal mechanisms of this invariance, we recorded activities from single cells in theExpand
Columns for visual features of objects in monkey inferotemporal cortex
AT early stages of the mammalian visual cortex, neurons with similar stimulus selectivities are vertically arrayed through the thickness of the cortical sheet and clustered in patches or bands acrossExpand
Relating Neuronal Firing Patterns to Functional Differentiation of Cerebral Cortex
We detected intrinsic features of cortical firing by devising a metric that efficiently isolates non-Poisson irregular characteristics, independent of spike rate fluctuations that are caused extrinsically by ever-changing behavioral conditions. Expand

The barn owl uses interaural time differences (ITDs) to localize the azimuthal position of sound. ITDs are processed by an anatomically distinct pathway in the brainstem. Neuronal selectivity for ITDExpand
Distribution of GABAergic neurons and terminals in the auditory system of the barn owl
Antisera to GAD (glutamic acid decarboxylase) and GABA were used to determine the distribution of GABAergic cells and terminals in the brainstem and midbrain auditory nuclei of the barn owl. The owlExpand
Toward a Unified Theory of Visual Area V4
Visual area V4 is a midtier cortical area in the ventral visual pathway. It is crucial for visual object recognition and has been a focus of many studies on visual attention. However, there is noExpand
Spinogenesis and Pruning Scales across Functional Hierarchies
Spinogenesis and synaptic pruning during development are widely believed to subserve connectional specificity in the mature CNS via Hebbian-type reinforcement. Refinement of neuronal circuit throughExpand
Disparity-tuning characteristics of neuronal responses to dynamic random-dot stereograms in macaque visual area V4.
Stereo processing begins in the striate cortex and involves several extrastriate visual areas. We quantitatively analyzed the disparity-tuning characteristics of neurons in area V4 of awake, fixatingExpand
Neuronal mechanisms of selectivity for object features revealed by blocking inhibition in inferotemporal cortex
The inferotemporal cortex (area TE) of monkeys, a higher station of the visual information stream for object recognition, contains neurons selective for particular object features. Little is knownExpand
Neural Correlates of Fine Depth Discrimination in Monkey Inferior Temporal Cortex
Binocular disparity is an important visual cue that gives rise to the perception of depth. Disparity signals are widely spread across the visual cortex, but their relative role is poorly understood.Expand
